David Charles Hahn

In 1994, a Boy Scout named David Charles Hahn attempted to make a neutron gun and in the process created a massive irradiation incident in his neighborbood and also irradiated himself. He was arrested. Authorities declared the his shed as a hazardous materials site and sealed it. Crews from the U.S. Environmental Protection Agency led a Superfund cleanup in 2005 that included dismantling the shed and shipping its remains to be buried at a low-level radioactive waste site in Utah.
