"For example, in 1953, the Public Health Service was asked to obtain milk samples in St. George, Utah, near the test site. But the service took a sample from a carton of milk purchased in a store, not from a local farm or dairy -- at a time when the majority of residents of southwest Utah obtained milk from their own cows and many others purchased milk from neighboring farms.(12)
According to Morgan S. Seal, a fallout monitor with the Public Health Service, the testing procedure was not very useful either. "In the case of milk, we even treated it with perchloric acid to get rid of all the organic residue....we knew for a fact then that those oxidating techniques completely eliminated any iodine in the material that you were treating."(13)"
This once again appears to confuse short term acute effects with long term cancer risks.
It should be pretty clear just from looking at the timeline. How are they going to discover a long term cancer risk by studying the population only eight years after exposure began?
There is plenty of evidence suggesting that exposure to low levels of radiation for extended periods increases cancer probabilities.
