Think about this for a minute. If three months of filming actually cause an increase in cancer rates the long-term residents of St. George (the downwinders), would have have devastatingly high cancer rates, right? The nearby residents were exposed to fallout from 100+ above ground nuclear tests and they were exposed for multiple decades, not just three months. This issue has actually has been studied and published in peer reviewed journals. A paper that studied the mortality of residents in that area concluded:

>...There was no excess risk of cancer mortality in southwestern Utah, for single or grouped sites, with the single exception of leukemia which showed statistically significant odds ratios of 1.45 based on 62 deaths at all ages, and 2.84 based on nine deaths at ages 0-14. The finding for childhood leukemia was based on different time periods and geographic comparisons from those of two earlier studies in which no such excess was found. Mortality from all cancer sites combined was significantly lower in southwestern Utah than in the remainder of the state, even after adjustment for the higher proportion of (lower risk) Mormons in southwestern Utah.

Trying to figure out when this strange idea about The Conqueror first appeared, I saw references to a 1980 article in People magazine. People magazine is not actually a peer reviewed journal.
