Date: 4 October 1967
Location: Harmarville, Pennsylvania, USA
Type of event: accident at industrial irradiator
A failure of interlocks on an industrial accelerator-type irradiator exposed three people to doses of 125-600 rem. The accident occurred at the Gulf Research Laboratory in Harmarville, near Pittsburgh. One worker received a 600-rem whole body dose, plus localized doses of 6600 rad to the feet and legs and 8800 rad to the hands and forearms. His hands and feet had to be amputated, but he survived largely due to a bone marrow transplant from his identical twin. Doses to the other workers were 300 rad and 125 rad. All three workers were protected from infection during recovery by reverse isolation.
Consequences: 3 injuries.
