In 1957, a young man named Darrell Robertson enlisted in the US Army and participated in a secret training programme in the middle of the Nevada desert. He and his fellow recruits were sworn to secrecy and, for decades, told no one of their experiences. In 1996, the US government declassified the project and Robertson was finally able to tell his story. In X-Ray Man, Robertson recalls training exercises in which the Department of Defense used him and other soldiers in nuclear tests more than a decade after the horrors of Hiroshima and Nagasaki were already well known.
