Did John Wayne die of cancer caused by a radioactive movie set? | WHAT REALLY HAPPENED

Did John Wayne die of cancer caused by a radioactive movie set?

I'm horrified to have to report this, John, but your girlfriend's claim is only slightly exaggerated. Of the 220 persons who worked on The Conqueror on location in Utah in 1955, 91 had contracted cancer as of the early 1980s and 46 died of it, including stars John Wayne, Susan Hayward, and Agnes Moorehead, and director Dick Powell. Experts say under ordinary circumstances only 30 people out of a group of that size should have gotten cancer. The cause? No one can say for sure, but many attribute the cancers to radioactive fallout from U.S. atom bomb tests in nearby Nevada. The whole ghastly story is told in The Hollywood Hall of Shame by Harry and Michael Medved. But let's start at the beginning.

The movie was shot in the canyonlands around the Utah town of St. George. Filming was chaotic. The actors suffered in 120 degree heat, a black panther attempted to take a bite out of Susan Hayward, and a flash flood at one point just missed wiping out everybody. But the worst didn't become apparent until long afterward. In 1953, the military had tested 11 atomic bombs at Yucca Flats, Nevada, which resulted in immense clouds of fallout floating downwind. Much of the deadly dust funneled into Snow Canyon, Utah, where a lot of The Conqueror was shot. The actors and crew were exposed to the stuff for 13 weeks, no doubt inhaling a fair amount of it in the process, and Hughes later shipped 60 tons of hot dirt back to Hollywood to use on a set for retakes, thus making things even worse.
