Clinical history: Acute skin blister and ulceration in a Peruvian patient 3 days after exposure. He inadvertently placed a 26-Ci (0.962-TBq) Iridium-192 source in his back pocket for 6.5 hours. At that time he complained of pain in his posterior right thigh. Eventually he developed massive ulceration and necrosis of the site with infection, and his right leg was eventually amputated.
