It is NOT the radiation. My brother in law works at a nuclear power plant up here in Canada. It is IMPOSSIBLE for radiation to travel through air this far from Japan to North America. Radiation breaks up by halves every so often so by the time it would reach the States or Canada..it will be all but dispersed. PLEASE stop whining and crying about some radiation from a country that is across the ocean, it does not affect us in the least. [/quote] I don't think I would stress the word impossible. Yes, some radionuclides have short half lives, others do not. Under normal operations I doubt it would be a problem....BUT, and BIG BUT at that, these reactors were blown to hell. There is NO prior history to base data on so neither you, nor your brother in law, can possibly tell us what the affects are.

Pasteurized, Homogenized Milk from the San Francisco Bay Area with Best By Date of 12/29/2011
Cs-134: 0.068 Becquerels/liter (Bq/l) ±0.011 [MDA=0.044]
Cs-137: 0.075 Bq/l ±0.015 [MDA=0.052]
Total cesium is .143 Bq/l, or 3.87 picocuries/l (pCi/l) (1 Bq = 27.1 pCi).
The EPA Maximum Contaminant Level for radioactive cesium in milk is 3 pCi/l:
“EPA lumps these gamma and beta emitters together under one collective MCL [Maximum Contaminant Level], so if you’re seeing cesium-137 in your milk or water, the MCL is 3.0 picocuries per liter; if you’re seeing iodine-131, the MCL is 3.0; if you’re seeing cesium-137 and iodine-131, the MCL is still 3.0.” -Forbes.com
Current levels are about 40% higher than what was detected 6 months ago:
