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.
1982年9月2日，挪威能源与技术研究所（位于克耶勒）的伽马辐照设施的一名员工，在未屏蔽的情况下带着一个65.7千居里的钴-60源进入了辐照室。受害者受到了未知剂量的辐射，并在13天后死亡。随后，利用电子自旋共振光谱法（ESR），根据事故发生时操作员携带的硝酸甘油片中长寿命自由基的产生情况，确定了此次事故中的辐射剂量。他因心脏问题使用硝酸甘油，而自由基很容易在作为药片主要成分的糖分中形成并被困住。进行了校准实验，确定事故期间给予药片的剂量为39戈瑞。基于这一结果的人体模型实验表明，此次事故中的平均全身剂量为22.5戈瑞。
