辐射环境下工作人员的剂量评估是辐射防护研究的重要内容之一。考虑到人员所处辐射场的不均匀性以及不同器官辐射敏感性的不同，需对人体及器官的辐射剂量进行精确评估。基于FDS团队自主构建的高精度中国辐射虚拟人Rad-HUMAN体素模型，本文发展了一种人体外照射剂量精确评估方法，并与传统人体剂量评估方法进行对比。结果表明，基于体素模型的人体器官辐射剂量评估方法能实现器官级的辐射剂量精确评估。目前该方法已集成至 FDS团队自主开发的核与辐射安全仿真系统RVIS中。

Worker’s radiation dose assessment in radiation environment is an important aspect of radiation protection research .Accordting to the inhomogeneity of the radiation field and difference of organs radiation-sensitive ,it is necessary for accurate assessment of the radiation dose of workers . Based on Chinese high-precision radiation virtual human model Rad-HUMAN developed by FDS team , an accurate human dose assessment method was developed .The results show that the voxel-based organs dose assessment method can achieve precise organ-level dose compared with traditional methods .At present ,the method has been integrated into the nuclear and radiation safety simulation system RVIS ,originally developed by FDS team .
