Thanks. But I was thinking, should I make sure my salads and strawberries are grown indoors? Should I try to find milk from indoor, grain fed cows? Avoid the grass fed meat we currently buy? That kind of thing. I am not pverstressing, just want to do the best I can, for my child who is under 50 lbs and the one who is under 4 lbs. (2nd trimester)
You could but I would not bother. My brother grew up at Hanford when radiation releases were common (mostly unfiltered plutonium work) and I was at the tail end of it. Same applies to all our peers. Water from the Columbia River and milk from local dairies had measurable contamination (Iodine-131 in particular). Exhaustive and extensive epidemiological studies have not demonstrated any definite impact on health in the population in the ensuing decades (although we all believe there must be an elevated community risk even if not statistically significant). There are some relevant cancers in the population, of course, but not clearly above the rate that would have occurred anyway.
What North Americans are experiencing now compared to the community exposure around Hanford in the 40s is just plain insignificant. I would not change the way I fed or raised kids in North America based on this event.
