I just came across this: http://www.dangerouslaboratories.org/radscout.html
It’s the story of a 15yo Boy Scout who tried to build a nuclear fusion reactor in his mother’s shed. He didn’t succeed in creating sustained cold fusion, but he did create enough fissile and radioactive material that the EPA had to come in and activate the National Radiological Emergency Plan.
He contaminated more than a city block with radiation and radioactive particles.
Favorite line from the story: “David earned a merit badge in Atomic Energy in May 1991, five months shy of his 15th birthday. By now, though, he had grander ambitions.”
