Last week I wrote about how Arizona Radiation Regulatory Agency (ARRA) instruments detected trace levels of Iodine-131 in AZ air from the troubled nuclear power plant in Japan. This week testing by ARRA and the AZ Dept. of Agriculture found trace levels of I-131 in the milk samples that they routinely monitor. The levels are of no public health consequence (they’re thousands of times lower than any level of concern). Still, it’s interesting that troubles with the plant on the other side of the Pacific can be detectable by these sensitive instruments. If you’re interested you can check out the data here.
Trace Levels of Iodine-131 found in AZ Milk

What about Iodine 129, I want to know the levels of that. Iodine 131 is the least of my concerns. With iodine 129 lasting 15.7 millions years and a biological half life of 100 days is insane! I want to know the levels of iodine 129 besides anything else such as the cescium and plutonium etc.
Iodine-129 is a product of nuclear fission but it is produced in very VERY small amounts. None has been reported in Japan, the water, air or in the US as a result of the Japan Incident.
