…Via radioactive fallout or some other vector in harmful doses?? How small of a radioactive dose is harmful?? it has been ascertained in the studies done by government radiation releases over the town of Hanford that small exposures to radiation are likely to have highly adverse effects on the human thyroid gland… frequently resulting in thyroid cancer. Small doses of radiation also may cause a high rate of birth defects… Please try to support your responses with useful information… this is something we should all discuss before advocating use of nuclear force on the middle east with our loved ones deployed in the region. Plus I just really want to know… because I thinks its important.
