VIENNA (AP) — The U.N. nuclear agency is reporting "very low" — but higher than usual — levels of radiation in the Czech Republic and elsewhere in Europe.
The International Atomic Energy Agency says the "very low levels of iodine-131 have been measured in the atmosphere over the Czech Republic" and elsewhere on the continent.
Iodine-131 ( 131 I), also called radioiodine (though many other radioactive isotopes of this element are known), is an important radioisotope of iodine. It has a radioactive decay half-life of about eight days. Its uses are mostly medical and pharmaceutical. It also plays a major role as a radioactive isotope present in nuclear fission products, and was a significant contributor to the health hazards from open-air atomic bomb testing in the 1950s, and from the Chernobyl disaster, as well as being a large fraction of the contamination hazard in the first weeks in the Japanese nuclear crisis. This is because I-131 is a major uranium, plutonium fission product, comprising nearly 3% of the total products of fission (by weight). See fission product yield for a comparison with other radioactive fission products. I-131 is also a major fission product of uranium-233, produced from thorium.

Thats a bit on the strange side.. I would have to wonder if it something from the cold war** coming back to bite us on the arse or if this is something new.. worrying indeed.
**as in old containers breaking down etc.

This is Iodine 131 it was created from fission with in the last 80 days most likely less this is a leak of a nuclear facility and needs to be found very soon.
The IAEA said it did not know the source of the iodine-131 and would give more details when available. It did not give details of the other locations in Europe where levels had been detected.
Iodine-131 can be "seen" by nuclear medicine imaging techniques (i.e., gamma cameras) whenever it is given for therapeutic use, since about 10% of its energy and radiation dose is via gamma radiation. However, since the other 90% of radiation (beta radiation) causes tissue damage without contributing to any ability to see or "image" the isotope, other less-damaging radioisotopes of iodine are preferred in situations when only nuclear imaging is required. The isotope I-131 is still occasionally used for purely diagnostic (i.e., imaging) work, due to its low expense compared to other iodine radioisotopes.
Text he Czech nuclear security authority said it had been detecting radioactive iodine-131 at a number of monitoring stations since late October and had informed the IAEA to see if it could identify the source, Reuters reports.
Czech nuclear safety chief Dana Drabova said the iodine could have leaked during production of radiopharmaceuticals.
It was certainly not from a nuclear power plant, she said, adding that they were almost certain that the source was abroad.
In the days and weeks after the Japan's accident, minuscule 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 US.
2011: As a result of the war, radioactive showers will destroy almost all life in the Northern Hemisphere. The remaining Europeans will face an even further threat from the Muslims who will use chemical weapons to finish them off.
In the body, iodine has a biological half-life of about 100 days for the body as a whole. It has different biological half-lives for various organs: thyroid - 100 days, bone - 14 days, and kidney, spleen, and reproductive organs - 7 days.
Long-term (chronic) exposure to radioactive iodine can cause nodules, or cancer of the thyroid.
Low doses can reduce activity of the thyroid gland, lowering hormone production in the gland
I love the way they always say it has a half life of 8 days. However, if you actually come into contact with it and it enters your body, e.g. through respiration, then that time increases significantly
