Lots of talk about I 131, but none on I 129. The latter isotope has a half life of 15.7 million years.
"129I is primarily formed from the fission of uranium and plutonium in nuclear reactors. Significant amounts were released into the atmosphere as a result of nuclear weapons testing in the 1950s and 1960s."
So it appears this disaster is a gift that will keep on given. Further, "129I is one of the 7 long-lived fission products that are produced in significant amounts. Its yield is 0.6576% per fission (U-235). Larger proportions of other iodine isotopes like 131I are produced, but because these all have short half-lives, iodine in cooled spent nuclear fuel consists of about 5/6 129I and 1/6 the only stable iodine isotope, 127I."
So have you been harmed? Have you volunteered to be irradiated? Is your food damaged. Your environment? How do you pay the medical cost for the harm done to you and your descendants in the future? Do you have standing within a class of folks who have been likewise been harmed? Is there a case for a claim here?
