Nowadays, when accidental exposure to ionising radiation occurs, clinical observations, and biological and physical investigations are usually taken into account to estimate the seriousness of the irradiation and, subsequently, to determine suitable therapy. A supplementary means based on a realistic numerical simulation of the accident situation may also be used, in order to assess the absorbed dose distribution inside the body. This can be particularly useful for localised irradiation, for which biological dosimetry is more often of limited relevance. This paper mainly describes the qualification of the computer code, the geometrical models and the techniques to reduce uncertainties. For specific configurations corresponding to the most frequent radiological accidents, all uncertainties are evaluated.
如今,当发生电离辐射事故时,通常会通过临床观察、生物和物理检查来估计辐照的严重程度,然后确定合适的治疗方法。此外,还可以使用基于事故情况真实数字模拟的辅助手段,以评估体内吸收剂量的分布情况。这对局部辐照尤其有用,因为生物剂量学对局部辐照的作用往往有限。本文主要介绍计算机代码的鉴定、几何模型和减少不确定性的技术。针对与最常见辐射事故相对应的特定配置,对所有不确定性进行了评估。
