Radiation

There has been a lot of concern over the trace amounts of radiation showing up in rain water, milk and elsewhere in the US. If you are 45 or older you probably grew up with a lot more radiation in the air, you milk, and other food than you are seeing now. All of our nuclear testing in nevada for 20 or more years after WWII is probably many times greater than we, here in the US, are seeing from the situation in Japan.
