Date: 17 November 1992

Location: Hanoi, Vietnam

Type of event: accident with irradiator


An accident occurred at a research-associated electron accelerator facility in Hanoi. An individual entered the irradiation room to adjust a sample for irradiation. The operators were unaware that the person had entered the room and turned on the beam at that time. The facility lacked safety interlocks or procedures to prevent such an accident. The individual received doses of 1,000 to 2,500 rad to the left hand and 2,000 to 5,000 rad to the right hand. Within one month one hand had to be amputated as well as the fingers on the other hand.

Consequences: 1 injury (localized dose)
