There are two primary types of smoke detectors: ionization and photoelectric.  Ionization smoke detectors are the most common type and have been around the longest.   Photoelectric detectors have not been commonplace until more recently and are still generally less common than ionization detectors.

Ionization detectors use a tiny amount of radioactive material, usually amercium-241, to ionize air in a small chamber in the detector.  When smoke particles from a fire enter the detector, they interrupt the ion potential of the air in the chamber, thus tripping the detector.

Photoelectric detectors work by using a tiny light emitting diode, usually infrared and a light detector.  A small gap between the light and the detector allows air to pass between the two.  When smoke particles enter the detector, they obscure the light beam and this triggers the detector.

Recent Opposition to Ionization Detectors:

In recent years there have been some groups that have sprung up claiming that ionization detectors are entirely unreliable and that the use of ionization detectors puts lives in danger due to their failure to adequately detect and warn of fire.   This is often accompanied with claims of some kind of conspiracy between authorities and smoke detector manufacturers to keep this information from the public.   The issue of radioactivity and claims of corruption by the nuclear industry as also been a fixture in the argument.

It may not be that surprising, in the end.  Given the rampant radiophobia that has gripped the world, even the humble smoke detector had to eventually become the subject of fear.

These arguments were used as the basis for an Australian documentary and advocacy project with the absurdly dramatic name “Stop the Children Burning.”

Here is a clip from the film:

In reality, there’s no danger posed by the tiny amount of Am-241 in smoke detectors.  Am-241 produces some low energy gamma rays, but is primarily an alpha emitter.  The material is present in microscopic quantities and is in a form that is non-soluble, chemically stable and not easily absorbed.  It can resist all but the most extreme temperatures, and if the temperature was that high, you’d have worse things to worry about than inhaling a tiny amount of Americium liberated from the detector.  In most cases, the Am-241 is in the form of an oxide or ceramic and is embedded in gold foil that is affixed to a steel disk, usually recessed.   It is specifically designed to make release of the material unlikely.

There is no requirement for special disposal of smoke detectors nor do they require a license to own or sell.  The total radiation exposure during normal operations is negligible and even in the most extreme cases of a release of the embedded material would still be too small for much concern. It has not been “declared fifteen times more dangerous than plutonium.” It is technically about fifteen times more radioactive per unit of mass because the half-life is shorter, but that also means a much smaller amount is needed to produce the same ionization effect than would be needed if plutonium were used.

This has got to be one of the most bizarre, crazy and just plain disgusting stories I’ve heard in a long time.

Chickenpox is a pretty nasty disease to have.  Like most adults, I went through it when I was a child because there was no vaccine at the time.  It was pretty misserable, but I was lucky, because despite missing more than a week of school and being covered with an  itchy, painful rash, I didn’t have any lasting effects.   Some are not so lucky.  It’s fairly common to be left with disfiguring scars, especially on the face, from chickenpox (I know a few people with such marks on their cheeks or forehead).   It’s less common, though not unheard of to have more severe and lingering effects and occasionally even death.

The virus tends to be less severe in children than adults, there was once a custom of intentionally infecting children with the disease.   So-called “pox parties” were held where children intentionally came into contact with others with chickenpox to get the disease when young.  Whether exposing children to the disease intentionally was ever a justifiable idea is debatable (most medical experts think it was always a bad idea), but it certainly is not any more.   These days, there is a vaccine for chickenpox that is highly effective and avoids the discomfort, suffering, dangers and possible disfigurement of the disease.   The vaccine is now part of the normal vaccine schedule and most children receive it.  Chickenpox is therefore far less common than it once was.

But what to do if you’re a vaccine fearing idiot?  Since the antivax crowd seems to think that getting infections is a good thing and boosts the immune system, a pox party seems like it would be right up their ally.  The only problem is that the vaccine has reduced the number of cases of chickenpox enough to make it difficult to find a good pathogen host to infect your kid with.   So what to do?   Why not use social networking to find other like-minded morons around the world and swap spit by mail with them.

The most popular and widely reported on Facebook group for doing this appears to have been recently shut down, but that’s unlikely to actually stop anyone in the long run.

I’m not even kidding…

I’m trying a new method of addressing the lunacy of chemtrails by showing that dumping chemicals at altitude wouldn’t generally do very much or be a very effective way of exposing populations to the chemicals that some claim are being sprayed.  It’s worth noting that the chemtrail loonies can’t even seem to agree on what is being sprayed, so here are some of the more common chemicals claimed.

If chemtrail conspiracy theorists are to believed, then large jet aircraft, possibly the same aircraft that carry passengers are being used to spray unknown quantities of chemicals of some type at high altitude.  While it’s rather difficult to judge the altitude of an aircraft by sight alone, based on what has been claimed to be chemtrails it’s fairly clear that the aircraft were flying at normal jet altitudes, well above tropospheric weather.   If they were indeed passenger aircraft then the altitude is generally above thirty thousand feet.

Some commonly claimed materials:

Between 1949 and 1951, the company Ac Gilbert produced and sold the “Atomic Energy Lab,” a kit of nuclear and radiation-related experiments intended for use by children in the same way that chemistry sets are used.   The kit included a sample of uranium-238, a Geiger counter, cloud chamber, spinthariscope and some other items used for educational experiments with radiation.  It also included at least three small radioactive sources.   It was modestly successful, likely due to the rather steep price of the set – $50, which would be equivalent to about $460 today.  (about 325 EUR, 285 GBP, 430 AUD)

The AC Gilbert set was certainly the most elaborate and complete atomic energy set sold, but it was not the only one. The American Basic Science Club produced a similar lab set around 1960, and Chemcraft produced a lab set in the late 1940’s to early 1950’s. In the 1950’s, some Chemcraft chemistry sets also included radioactive materials and experiments that could be done with radiation.

I have always thought that these sets were an incredibly good idea and a really excellent way to acquaint young people with the basics of radioactivity and, importantly, demonstrate that radiation is common and not something to be feared. These lab sets were extremely safe. The amount of radioactive materials present in the experimental sources was microscopic and not at all dangerous. The uranium ore or uranium compounds included are not a radiological hazard and are only a toxicity hazard if they are ground up and snorted or otherwise inhaled, and even then, are less toxic than an equivalent quantity of something like lead.

There’s really no better way to get a kid acquainted with science than to actually do some hands-on activities. They improve understanding and retention and allow them to participate directly in making exciting observations. Anyone lucky enough to have had one of these labs as a child probably grew up with a healthy understanding (and not fear) of radioactivity.

Sadly, the world has changed since the early 1950’s, and today most people seem to run around with rampant radiophobia. If something is “radioactive” (which nearly everything is) then it’s seen as being of the highest danger. Nothing is believed to be more environmentally destructive, more dangerous to health, more disastrous, more hazardous and more terrifying than radiation. The idea that at one time children were allowed to learn with materials that produce radiation significantly above background levels fills some with horror and others laugh at just how stupid everyone must have been fifty years ago.

Here’s some of the things that have been said about the AC Gilbert Atomic Lab:

From the Daily Grind:

World’s Most Dangerous Toys: Gilbert U-238 Atomic Energy Lab
If you thought choking hazards in toys were bad then spare a thought for American kids in the early 50′s.

Introducing the Gilbert U-238 Atomic Energy Laboratory. This toy lab set was produced by Alfred Carlton Gilbert between 1950 and 1951 and sold for $49.50US (which is equivalent to about $380 – $400US dollars today). So if you were lucky enough to have well off parents back in the day you may well have been ‘lucky’ enough to get your hands on this radioactive fun set.

From Liveleak:

Very bad toys: Atomic Energy Lab usa ca. 1960
t’s unclear what effects the Uranium-bearing ores might have had on those few lucky children who received the set, but exposure to the same isotope
U-238 has been linked to Gulf War syndrome, cancer, leukemia, and lymphoma, among other serious ailments. Even more uncertain is the longterm impact of being raised by the kind of nerds who would give their kid an Atomic Energy Lab.

The 8 Most Wildly Irresponsible Vintage Toys
#1. Atomic Energy Lab

As a kid, did you ever swallow or at least put in your mouth a small piece of a toy or play set? Did you grow an extra arm because of it? No? Then you probably didn’t have the Atomic Energy Lab.

You see, there was a different approach to nuclear power in the ’50s and early ’60s — atomic energy was our friend and the way of the future, and it would never do anything to hurt us. However, it’s still hard to believe that anyone would entrust kids with radioactive material (even in small doses).

Yet, the Atomic Energy Lab kit produced by the American Basic Science Club came with real samples of uranium (which is radioactive) and radium (which is a million times more radioactive than uranium). Since the mere presence of radioactive material in a children’s product clearly wasn’t insane enough, some of the experiments detailed in the manual also required kids to handle blocks of dry ice. Dry ice, by the way, has a temperature of minus 109.3 degrees Fahrenheit, and it’s recommended that it only be handled while wearing gloves (none were included).

Okay, they’ve got a point about the dry ice, although it’s reasonably safe to handle with basic precautions. Still, I’m downright offended by the way that people completely ignorant of what radiation is or the dangers can sit there and smugly dismiss the idea of a radiation experiment set as being insane. It’s often ranked the most dangerous toy of all time, but in fact, it’s not dangerous at all for any normal 12 year old to learn from a microscopic amount of a radioisotope or a little bit of uranium ore, which they may well have sitting in their backyard anyway.

I’ll go one further:  Not only do I think this was a great idea and a very positive learning experience, I also think that there has never been a better time for something like a radiation and nuclear energy lab set!  Having a set that had a good variety of experiments would be fairly expensive but not unaffordable.  It would be targeted at ages 12 to adult and could also be something science departments at schools might be interested in.

I’m seriously considering doing it!  I’ll take the flack for selling kids a horrible cancer-causing evil material if I have to, because somebody has got to do it, and if I get enough interest I may very well start putting some kits together.

A cautionary tale of how medicine can become far too accepting of a procedure of limited value and great potential for harm…

First, some background on the lobotomy:

The lobotomy may well be the most notorious and misunderstood medical procedure ever to have been developed.   It’s the butt of many jokes and is portrayed widely in the media as a savage operation preformed on those who were unruly as a means of turning them into dribbling vegetables, incapable of resisting and placid in all respects.  This is partially true, but is an overly simplistic portrayal of what the lobotomy really was and how it was used.

To understand the use of the lobotomy one must first realize the environment it was developed in.  Prior to the mid 20th century, there was very little that could be done for the severely mentally ill. Psychotherapy existed and was useful in helping those with problems like anxiety, phobias and depression better manage their symptoms, but this could do little for the truly insane. For those who suffered from severe delusions, violent episodes, severe depression with suicidal tendencies, extreme bipolarism, there was no effective therapy.

Such individuals were placed in mental institutions, where they were often forced to live the entirety of their lives.   Often miserable places, institutions provided little more than warehousing for many individuals.   Mental institutions were enormous, becoming huge communities onto themselves.  Attempts were made to make life more pleasant by providing  classes and recreation, but the enormous expense of caring for the populations made that difficult to do on a large scale.   The worst cases were often left restrained or locked in padded cells.  With so many completely crippled by mental disease, conditions could easily degrade to the point where wards became filthy and filled with the screams of insane patients.

The origins of psycosurgury can be traced back to the 1880’s, when Gottlieb Burckhardt, a Swiss neurosurgeon began to experiment with operations on the brains of the most severely insane. Small sections of brain were removed in the hope that it might calm the continual mania of the patients operated on. The results were not encouraging, but research continued into the 20th century. It was known that traumatic brain injury, brain tumors or their removal could alter a person’s personality, but only the most basic understanding of the regions of the brain associated with various aspects of thought and emotion existed.

The lobotomy was developed in 1935 by Portuguese doctor António Egas Moniz, who intitially called the procedure the leukotomy. Moniz had become aware of experiments carried out on apes in which portions of the brain were intentionally removed or disconnected. Operations that removed the frontal lobes had a major effect on the learning capacity of the animals, but also made them more placid and less prone to expressions of frustration and emotional outbursts. He believed that doing so on humans might allow those with the most violent psychiatric episodes to lead more normal lives, or at least be more manageable. Early experiments involved injecting alcohol into the nerves that connected the frontal lobes to the rest of the brain. This was later replaced by simply cutting the connections.

The belief at the time was that mental illness was caused by areas of the brain becoming too active or the brain being overstimulated and going haywire with out of control signals. It was thought that there was simply too much emotional activity that that cutting away the overly active portions of the brain would relieve this. While this belief is not always entirely false, it’s overly simplistic and does not apply to most cases of mental illness.  While there are portions of the brain that are associated with certain functions or aspects of personality, it is far too complex for a single region to be defined as the source of something like delusions, violent episodes or depression.

Still, the procedure did appear to have some validity. Many of those who received the operation did indeed become calmer and more easy to manage. Contrary to popular belief, it did not necessarily render the individual incapable of speech or basic function, although this did sometimes happen. It seems that overall, the results were highly variable. This is likely attributable to the simplicity and crudeness of the surgery. It involved drilling holes in the head of patients and cutting the pathways by inserting instruments. Exactly what kind of effects this had on the brain could vary quite a bit, especially since the individuals it was preformed on had all manner of conditions to begin with.

Early observations considered the outcome of the procedure to be result in a 33% to 33% to 33% success rate. In other words, roughly one third of patients could be considered to have improved from the operation. One third could be considered to be worse than before the operation and one third were roughly the same. This is hardly a stellar success rate, but given the lack of options for the worst cases of mental disease, it may have seemed worth the risk. There certainly were a few cases of individuals who seemed to gain extensive relief with few complications, but these were relatively rare.

A few individuals died during the procedure.  Others were left completely incapacitated and severely disabled.  Many, however, did retain their basic abilities to communicate and do simple tasks.   Some lost the ability to walk or talk but subsequently relearned it.   A number of reports indicated that the patients became very child-like and lost the ability to comprehend complex concepts.  Lack of emotional responses or social capacity was also reported.   Another effect was the loss of inhibitions.  Many seemed to have no fear or anxiety, even in circumstances where it would be appropriate.  Apathy and social disconnection were common.  Many patients began to overeat and put on large amounts of weight.  Some developed complications ranging from incontinence to lack of balance to sleep disorders.

The psychiatric community accepted the procedure with varying levels of enthusiasm. It gained rapid acceptance across the world, but many remained uneasy about the implications and ethical considerations. It was used primarily on the worst of the worst cases, at least initially. Directors of mental hospitals welcomed anything that could make it easier to manage their overcrowded wards, resulting in an expansion of use that raised questions about whether it was really being used as a last resort. Overall, the procedure was never without controversy, but given the lack of alternatives, it often was considered about the only thing that could be done to at least try to relieve severe mental illness.

I started thinking about this topic after the discussion on an other post regarding loss of electricity turned to railroad crossings (grade crossings), where railways intersect roadways.   Understandably, loss of power for warning signals can result in some safety problems.

Unfortunately, adding entirely redundant backup power to railroad crossing warning systems wouldn’t actually address the real safety problem with railroad crossings:  idiots.    It’s really not hard to avoid being killed at a railroad crossing.   If there’s a train coming, don’t enter the crossing.   If there isn’t a train coming, it’s safe to cross.    It’s not hard to tell if a train is approaching either.   Most crossings have signals, such as flashing lights and gates to make it obvious, but even if the crossing lacks signals or the signals don’t work, it’s still fairly obvious.   Trains are generally required to blow their horn when approaching a railroad crossing, so if you’re about to go over a railroad crossing and hear a train horn, look both ways, because it’s possible that the signals are not functioning.

Seems simple, right?  After all, stopping at a railroad crossing to let a train pass is only going to cost you, at worst, a few minutes, and cutting in front of a train is not a good way to keep yourself alive.    It’s impossible for the train to stop in time to avoid a collision, and it certainly can’t swerve out of the way.  Estimating the speed and distance of  something like an approaching locomotive can be surprisingly difficult, especially when you’re also moving.   If you’re wrong and that train hits, it’s not going to do just superficial damage.

Despite these seemingly obvious facts, grade crossings claim a surprising number of lives.   In the US alone, hundreds die in grade crossing accidents every year – 247 in the year 2009 and 338 in 2007.  The problem is not confined to the US, of course.   Everywhere that grade crossings exist, there are deaths on a fairly regular basis.

Supporters of Social Darwinism might suggest that this is not such a bad thing, since it’s generally the fault of the idiot driver who gets killed, but the problem is more broad than that.  Despite the fact that locomotives tend to be a lot larger and sturdier than road vehicles, they can and do get badly damaged by striking cars and trucks.   Debris can fly up and injure train crew.  On occasion, trains have even derailed due to grade-crossing accidents.   Even if the accident does not cause any significant damage to the train, it still means that it has to come to a stop, the crossing ends up being blocked for some time and emergency services need to respond to clean up the mess.   And the idiots who try to beat the train are actually more likely to survive with injuries than die outright.   Add to this the fact that there may be other passengers in the vehicle who had no control over the situation and it’s easy to see why this is a major social problem.

It’s an age old question:  What’s better for the environment?  Smaller and less prone to consuming fuel or large and more sophisticated and controlled.  Many seem to think that smaller is inherently better and advocate everything from smaller power plants to smaller farms, and in both cases, more of them.

An obvious area of debate is transportation, especially in terms of cars versus motorcycles.   There’s no doubt that motorcycles are smaller, with smaller engines and less dead weight being hauled around to carry a single passenger.   They use less fuel than cars.

So are they better for the environment?   The Mythbusters take on this question in an episode that will be airing some time in the upcoming season.

Via the LA Times:

‘MythBusters’ asks: Are motorcycles greener than cars?
A trend is afoot, according to “MythBusters” television host Adam Savage: “People are trading in their cars and driving motorcycles instead because they believe that’s the more environmentally friendly choice,” Savage said in Wednesday’s season opener of the popular Discovery Channel show. “The logic is because motorcycles are generally more fuel-efficient than cars, they burn less gas and thus they must be better for the environment.”

The question is: Are they really? As the MythBusters have done with each of the show’s previous seven seasons, Savage and his co-host Jamie Hyneman set out to test the theory.

Selecting three motorcycles and three cars that represented popular models from the ’80s, ’90s and ’00s, they put the six vehicles through a 30-minute, 20-mile course. Seventy-five percent was freeway driving; the other 25 percent was in the city. Savage drove the three cars. Hyneman trailed him at speed on each of the three bikes. None of the vehicles’ makes and models were disclosed.

All of the vehicles were equipped with portable emissions-measuring systems that took exhaust gases from a probe in the tailpipe and engine information from the engine control unit. The devices determined the vehicles’ fuel economy and emissions profiles while the vehicles were running on the real-world course in California’s Alameda County earlier this year.

The upshot? Motorcycles were indeed more fuel-efficient than cars and emitted less of the greenhouse gas carbon dioxide, but they emitted far more smog-forming hydrocarbons and oxides of nitrogen, as well as the toxic air pollutant carbon monoxide. For the most recent model year vehicles tested — from the ’00s — the motorcycle used 28% less fuel than the comparable decade car and emitted 30% fewer carbon dioxide emissions, but it emitted 416% more hydrocarbons, 3,220% more oxides of nitrogen and 8,065% more carbon monoxide.

The MythBusters’ conclusion: “At best, it’s a wash. Motorcycles are just as bad for the environment as cars,” Savage said on the show. “At worst, they’re far worse.”
…
In the 2011 American Lung Assn. State of the Air report, eight of the top 10 cities for ozone pollution were in California. Los Angeles ranked first.

Despite the MythBusters’ findings, emissions are only part of the story of a vehicle’s true greenness. According to the Motorcycle Industry Council, motorcycle manufacturing requires thousands fewer pounds of raw materials than automobiles. They require less fossil fuel, so they require less energy to pull that fossil fuel out of the ground. They use fewer chemicals and oils than cars. And motorcycles produced today are 90% cleaner in California than they were 30 years ago.

Note to MythBusters: How about a cradle-to-grave life cycle assessment for cars and motorcycles for the Season 9 opener?

It’s definitely a complicated issue, especially when one considers the issue of the actual resources that go into one of these vehicles, what impact they may have in terms of displacing other vehicles and how they are driven. Given the differences in driving habits and engine types and efficiency, it’s very difficult to make a one-to-one comparison between motorcycles and automobiles.

Motorcycles are certainly smaller and have a lot less metal in them. However, motorcycles don’t generally age gracefully, especially if they are driven often and therefore may need more frequent replacement. Additionally, many of those who own a motorcycle feel the need to also own a car, since cars have greater utility and can be used when the weather precludes the use of a motorcycle, so owning a motorcycle does not really displace the resources that go into a car.

As most here probably know, Dr. Jack Kevorkian died this year at age 83.   Dr. Kevorkian become famous for his championing of doctor assisted suicide in the United States, where doing so is illegal in most jurisdictions.  Kevorkian is known to have assisted in the suicide of at least 130 persons.   His advocacy for doctor-assisted suicide began in the early 1980’s and the first suicide which he publicly acknowledged participating in was in 1990.

Kevorkian was most prolific in his activities between 1991 and 1998.  During that time he traveled around the United States aiding individuals in taking their own lives.   Kevorkian designed the equipment used, which included an IV drug machine and a carbon monoxide respirator.   He attached patients to the machines but did not take the final step of pushing the plunger or opening the valve.  That was done by the patients, and to some extent, insulated him from being easily prosecuted.   Still, he was in and out of court many times during the 1990’s.   He lost his license to practice medicine and was repeatedly ordered to stop his activities.

Kevorkian loved the attention that the controversy generated.   His court dates became media circuses and he never passed up an interview.  Kevorkian would always say that he was fighting for the right of a person to control their own destiny, die with dignity and relieve their own suffering.   However, many of his antics were not exactly dignified.

In 1998, Kevorkian appeared on the news program 60 Minutes and showed a videotape of the assisted suicide of Thomas Youk, a 52 year old ALS sufferer.   Youk expressed his desire to die and gave his full consent to the procedure to end his life.   In this video Kevorkian did something he had never publicly admitted to before, he pushed the plunger that delivered the lethal drugs himself.   Kevorkian also directly dared authorities to convict him of murder for his actions.   This time he bluffed a bit too hard.  They did and he was sentenced to ten to twenty five years in prison.  Kevorkian was finally paroled in 2007.   Since then he spent a bit less time in the media spotlight.   As a condition of his parole he agreed to no longer preform any kind of suicide service or provide any advice on the matter.

With the recent death of Kevorkian, there has been a lot of talk about his life and accomplishments.   A large number of individuals who identify with atheism, humanism, libertarianism and other related movements have been quick to praise Kevorkian.  Those who believe that a person should have the right to die often cast him as a hero, fighting for a basic human liberty and for the merciful release from pain and suffering.   This is not new.  During his life, Kevorkian was portrayed as a hero by a number of groups and activists.  In 2010, Al Pacino portrayed Kevorkian in the television movie “You Don’t Know Jack,” which showed Kevorkian as a compassionate activist fighting to legalize dying by choice.   Kurt Vonnegut’s collection of short stories published under the title “God Bless You Dr. Kevorkian,” was more of a spoof than a tribute, but Kevorkian seems to have enjoyed the attention anyway.

Sorry, but I can’t agree. I find the man despicable.

You may notice that there’s something a bit off here.   Claims that vaccines are a dangerous conspiracy purported by horrible pharmaceutical companies are usually associated more with the Loony Left of the political spectrum, while Bachman is decidedly on the Loony Right side of the isle.  It’s interesting to note that different ridiculous beliefs tend to come from different sides of the isle.   Vaccine conspiracy theories tend to center on mistrust of corporations and capitalism in general and are often part and parcel of theories of how the military and big corporations are killing us with fluoride, chemtrails and depleted uranium, which means we all need to embrace the “natural way” and move back to mud huts where we can practice free love and drop acid.

You’ll notice, however, that Backmann is not opposed to vaccinations in general, but is singling out one vaccine which apparently has a nearly magical power to steal the innocence of sweet lovely little twelve year old and make them retarded.   The reason that conservatives are so opposed to the HPV vaccine is that it’s seen as somehow encouraging sex or that requiring it is somehow offering a government endorsement of premarital sex.   It’s an extremely warped view when one considers that they’re effectively saying that they are so opposed to what they consider to be offensive forms of sex that it’s worth avoiding a vaccine that could wipe out most cervical cancer.

Her sentiment seems to have been touched off in part by the state of Texas adding the HPV vaccine to the required immunizations for school admission for girls.   This was done by another Republican presidential candidate, Rick Perry.   Some have accused Perry of taking pharmaceutical money for this policy, it really does not change the fact that it’s a good idea to have girls vaccinated.   If he did do so because he was paid off, then all he can be accused of is doing the right thing for the wrong reason.

This is the kind of story that really burns me up.   General fear and ignorance by both authorities and the public is once again making life unnecessarily problematic for someone who didn’t do anything wrong.

Daytona Beach News-Journal:

Stetson student found with uranium on DeLand campus
Stetson University officials confiscated a package containing low-grade uranium from a student Thursday, DeLand police said.

Volusia County’s HAZMAT team, DeLand police and firefighters were called to the scene. Authorities discovered that the amount of uranium was small enough that it could be possessed legally.

Police said there was no immediate threat to the campus, but the Public Safety Office was temporarily sealed off as a precaution.

According to Cindi Brownfield, Stetson spokeswoman, possession of uranium falls under the university’s weapons policy, and the student will go through Stetson’s judicial process.

DeLand Deputy Chief Randel Henderson said in an email that police are “conferring with the FBI as a routine protocol.”
