...But of these sophisms and elenchs of merchandise I skill not...
Milton, Areopagitica

Except he had found the
standing sea-rock that even this last
Temptation breaks on; quieter than death but lovelier; peace
that quiets the desire even of praising it.

Ever since nuclear testing began it has been very difficult to get a useful accounting of human exposures to the fallout from these tests. Partly this was motivated by military secrecy, partly by a desire to allay public fears (i.e public relations reasons), and partly by a fear of possible legal action by actual of potential victims. Some exposure related incidents have been revealed due to the impossibility of hiding them: namely the high radiation exposures of the Marshallese and the Japanese aboard the Fifth Lucky Dragon after the Castle Bravo disaster. But most information on this subject has been withheld, deliberated buried in obscure reports, or never collected (this is the principle of being careful not to learn what you don't want to know). This information has slowly come to light in bits and pieces over the last 20 years.

What is probably the most important study of the health effects of testing were announced by the National Cancer Institute in August of 1997, and released in October. The study report is now available on line: National Cancer Institute Study Estimating Thyroid Doses of I-131 Received by Americans From Nevada Atmospheric Nuclear Bomb Test.{possible redirect/dead link}
The basic finding of the report is that internal exposures to radioiodine (I-131) in fallout from continental nucelar testing was the most serious health consequence. Radioiodine concentrates in milk when consumed by cows when grazing, and then concentrates in human thyroid glands when contaminated milk is ingested. This concentration effect is especially strong in children. The NCI study estimates that the average American alive at the time received a thyroid radiation exposure of 2 rads, with some people receiving up to 300 rads. The effect of these exposures is to boost the chance of contracting thyroid cancer some time during a lifetime. This cancer is normally not very rare, and is highly treatable (as cancers go). It is possible to estimate the overall effect of the total radiation exposure of the American population. From the 380 million person-rads of total exposure roughly 120,000 extra cases of thyroid cancer can be expected to develop, resulting in some 6,000 deaths [See note]. For comparison, the worst industrial disaster in history (Bhopal, India; 3 December 1984) killed about 3000 people and injured 150,000.
