One problem with tuna is they try to catch the largest ones which over years will have the greatest build-up of toxic products. Any word on what has happened to our air as a result of Fukishima?
I’ve seen computer modeling re Fukushima in March. Showed Xenon throughout Northern Hemisphere for several days and modeling showed snake like wisps of radioactive Cesium and Iodine sweeping to AK and down the coast to Northern CA while some came laterally from the West to Central CA then moving inland. This sort of model doesn’t indicate altitude of fumes. I recall hearing that Boise Idaho had highest count of radioactive iodine in rainwater and that a location in VT dumped dairy milk for iodine or cesium (I forget) and some Hawaiian dairies added boron to cattle feed to lower contamination in milk. Those computer modeling programs I mentioned earlier were from Europe. The Ex-SKF blogger had 3 links to foreign agencies projecting airborne fallout but he noted that all 3 halted monitoring.
UC Berkley reported on Feb. 6 that contamination testing revealed radioactive cesium in San Francisco milk sample ‘highest since August’ and at 150% of EPA limit (EPA Maximum Contaminant Level for radioactive cesium in milk is 3 picocuries/L and this test found 4.5). Now I don’t know if it’s ‘highest since August’ because contamination continues to blow in from the west or because the cattle were given fodder that originally had higher amounts of contamination. Here’s the UC Berkely link: http://www.nuc.berkeley.edu/UCBAirSampling/MilkSampling
The leakage from Fukishima was much less than any of those large atmospheric nuke tests in the 1950s and 1960s — and the only precaution we had to take back then was not to eat snow, and some schools and other institutions stocked iodine pills.
