I129 - What say you, BRAWM?
It's been brought to my attention that following these nuclear accidents and radiation releases, the focus is rarely (never) on Iodine-129, a low-level beta emitter, half life about 250 thousand years.
I have been told (by an industry scientist) that the (previous) presence of I131 at significant levels assures us that I129 is present. He did not understand why no one tests for I129, since, depending upon its levels, would be a factor to consider in children's exposure levels.
I asked him if we could determine the I129 level based upon a ratio to I131 based upon the Fukushima releases, and he said not anymore since the initial releases of 131 are now gone. He did say that a correlation may be possibly made to the Sr90 levels.
Mark, can you enlighten us as to the risk posed by I129 exposure, and share your educated opinion / knowledge about its levels in our environment, pre- and post-Fukushima?
Thank you, MM
