In 1957 these guys volunteered to stand under a nuclear bomb test. This video is remarkable. It's not gory at all, which is a little surprising.
This happened at a Nevada test site. Radiation and fallout drifted into St. George, UT.
"The folks in St. George were repeatedly hit by uninvited fallout. . . . In 1953, one test, codenamed "Harry" actually deposited
quite a lot of fallout on St. George, to the point where residents were
forced to stay inside for many hours, and prohibited from washing their
cars until they became less radioactive."
Cars get and subsequently become less radioactive? I did not know that. The 50s seem so quaint. But that atomic bomb stuff is grisly.
