Abstract

An attempt was made to estimate organ doses of a victim in a high-dose non-homogeneous exposure accident caused by a sealed 192Ir gamma-ray source. The Gilan accident was selected as a case study. Organ doses including testis, red bone marrow and so on were properly estimated by applying the Monte Carlo calculation with the state-of-the-art adult male Mesh type Reference Computational Phantom. By introducing a complicated exposure scenario, the dose distribution on the right chest of the victim in the Gilan accident could be reproduced to a certain extent.

尝试通过最先进的网格型参考计算模型--IR-192 辐射源事故案例研究，重新估算非均质辐射事故中受害者的器官剂量。

我们试图估算密封的 192Ir 伽马射线源造成的高剂量非均质照射事故中受害者的器官剂量。选择吉兰事故作为案例研究。通过使用最先进的成年男性网格型参考计算模型进行蒙特卡洛计算，对包括睾丸、红骨髓等在内的器官剂量进行了正确估算。通过引入复杂的照射情景，在一定程度上再现了吉兰事故中受害者右胸的剂量分布。

期刊介绍： Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
