Abstract
On 2 September, 1982, one of the employees of the gamma-irradiation facility at The Institute for Energy and Technology (Kjeller, Norway) entered the irradiation cell with a 65.7-kCi 60Co source in unshielded position. The victim received an unknown radiation dose and died after 13 days. Using electron-spin resonance spectroscopy (ESR), the radiation dose in this accident was subsequently determined based on the production of long-lived free radicals in nitroglycerol tablets carried by the operator during accident. He used nitroglycerol for heart problems and free radicals are easily formed and trapped in sugar which is the main component of the tablets. Calibration experiments were carried out and the dose given to the tablets during the accident was determined to be 39 Gy. Phantom experiments based on this result indicate an average whole-body dose in the accident of 22.5 Gy.
