[quote]Iodine-131 is a dangerous radioactive isotope. It can clog up your thyroid gland and contaminate food. It's been a big problem in Japan (for obvious reasons), but now it's been scarily detected throughout Europe. And nobody knows the source.
Germany, Hungary, Slovakia, Austria, Sweden, and the Czech Republic have all detected clouds of iodine-131 within their borders—that's a very large swath of Europe. Nobody is sure of where it's coming from, Reuters reports, though speculation includes pharmaceutical companies, nuclear submarines, and the transportation of radioactive materials—but scientists are sure it's not from Fukushima. So how would that explain contamination that spans hundreds and hundreds of miles?
The International Atomic Energy Agency says "the current trace levels of iodine-131 that have been measured do not pose a public health risk," but we've heard that so many times before. It's not a cause for panic, but an unexplained cloud of dangerous radioactivity is absolutely cause for concern. It certainly deserves more than 129 words on the IAEA's website.[/quote]

[quote](Reuters) - Very low levels of radioactive iodine-131 have been detected in Europe but the particles are not believed to pose a public health risk, the U.N. nuclear agency said Friday, saying it was seeking to find the source.
The International Atomic Energy Agency (IAEA), the Vienna-based U.N. watchdog, said it did not believe the radioactive particles were from Japan's stricken Fukushima nuclear power plant after its emergency in March.
Experts said the origin of the radiation -- which has been spreading for about two weeks -- remained a mystery but could come from many possible sources ranging from medical laboratories or hospitals to nuclear submarines.
The Czech Republic's nuclear security watchdog said it had tipped off the IAEA after detecting the radiation it thought was coming from abroad but not from a nuclear power plant. It suggested it may come from production of radiopharmaceuticals.
Germany's Environment Ministry said slightly higher levels of radioactive iodine had been measured in the north of the country, ruling out that it came from a nuclear power plant.
Hungary, Slovakia, Austria and Sweden also reported traces at very low levels that did not pose a health risk.
Iodine-131, linked to cancer if found in high doses, can contaminate products such as milk and vegetables.
Paddy Regan, a professor of nuclear physics at Britain's University of Surrey, said the suggestion that it may have leaked from a radiopharmaceuticals maker "sounds very sensible and totally reasonable."
He said since iodine was used in the treatment of thyroid conditions it was also likely that hospitals in many European countries would have it in their stores.
"It would be very unlikely for it to have come from Fukushima since the accident was so many months ago and iodine-131 has a brief half-life," he said.
Iodine-131 is a short-lived radioisotope that has a radioactive decay half-life of about eight days, the IAEA said.
Massimo Sepielli, head of the nuclear fission unit of Italy's national alternative energy body ENEA said any number of sources could be to blame for the readings.
"It could be coming from the transporting of (nuclear) material, it could come from a hospital ... it could even come from a nuclear submarine, even if it's a more complicated possibility ... but you can't rule that out."
CAREFULLY CONTROLLED
Professor Malcolm Sperrin, director of medical physics at Britain's Royal Berkshire Hospital, said any link with Fukushima was extremely unlikely.
"It is far more likely that the iodine may be as a result of excretion by patients undergoing medical treatment. Whilst such patients are carefully controlled, some release of iodine into the environment may be inevitable but would certainly be well below any limits where health detriment would even begin to be an issue for concern," he said.
The IAEA said the Czech Republic's nuclear safety body had informed it that "very low levels" of iodine-131 had been measured in the atmosphere over the country in recent days.
"The IAEA has learned about similar measurements in other locations across Europe," the brief statement said.
"The IAEA is working with its counterparts to determine the cause and origin of the iodine-131."
The Czech watchdog said it had detected iodine-131 at a number of monitoring stations since late October. It said there was no health risk from the iodine.
"It was detected by our radiation monitoring network, with probability bordering on certainty the source is abroad. It is iodine-131 and we have asked the IAEA if they know what the source could be," Czech State Office for Nuclear Safety chief Dana Drabova told Reuters.
Officials in Spain, Russia, Ukraine, Finland, France, Britain, Switzerland, Poland and Norway said they had not detected any abnormal radiation levels. Romania's watchdog said there had been no incident at the country's sole nuclear plant.
Austria's Environment Ministry said small levels were measured in the east and north of the Alpine country, saying the estimated dose level for the population was one 40,000th of the dose of radiation received in a transatlantic flight.
In the world's worst nuclear accident since Chernobyl in 1986, an earthquake followed by a massive tsunami overwhelmed the Fukushima plant in Japan, causing a reactor meltdown and leakage of radiation, including of iodine.
In the days and weeks after the accident, tiny amounts of iodine-131 believed to have come from Fukushima were detected as far away as Iceland and other parts of Europe, as well as in the United States.

Can we please stop with the nuclear incidents for at least this year world? I mean come on.
No health risk.
also late
usual nuclear fearmongering
There's no problem here, it's obvious that this is a paid fabrication of someone who's company or government gets more money from other sources of energy and thus is just trying to scare people into not using a safer form of energy. Nuclear scare tactics are fun huh guys?
Isn't pretty much everything slightly radioactive?
[QUOTE=kidwithsword;33299798]everything is slightly radioactive[/QUOTE]Fixed
If it does not pose a health risk, who gives a shit. Still wondering where did it come from.
Well it's better than having another radioactive zone.
What for radioactive Iodine is used to diagnose? And treat too. Some hormone gland I think.
Free diagnosis!
I'm pro-nuclear and all, but it's somewhat troubling when you find out that there's plumes of radioactive particles floating around all over Europe and nobody has a fucking clue why. The source NEEDS to be determined.

It might just be natural. AFAIK radioactivity is natural and so could be random particles like these.

'Radioactivity' is a huge umbrella term. Iodine-131 is NOT an isotope that naturally turns up in huge quantities on Earth. Any radiation from within the Earth's core is usually found in the form of alpha particles (helium nuclei, which is basically where humanity's helium supplies come from - radioactive decay underground that releases ionised helium atoms). Iodine is such a huge atom that you'd need fission of something like uranium atoms to obtain it.
In fact, that's one of the main sources of Iodine-131 - the fission of uranium. Iodine-131 was of huge concern during atmospheric nuclear testing when America was doing that kind of stuff regularly (and also when Chernobyl went kablooey). It's presence now is of some concern to say the least.
Someone fucked up making radiopharmaceuticals and who would want to open themselves up to liability and bad PR by admitting it was therm
it's not concerning at all sltungle, not at present concentrations
The Zone is calling us
