这项研究在健康物理学和辐射防护方面的作用已被实施，以评估通过肺部吸入沉积在肺部的大气气溶胶粉尘中的放射性铯粒子所发射的伽马射线（光子）和β粒子所产生的内部剂量（相对于承诺当量剂量）和剂量分布成像。使用PHITS代码与人肺的体素模型数据（DICOM格式）相结合。我们已经处理过不溶性含放射性铯的水颗粒（直径约 2.6 m）迁移到呼吸系统中 ET1、ET2、BB、AI-bb、LNET 和 LNTH 六个区域中的任何一个区域，直到落入血管。源参数是成年男性在户外呼吸典型空气量时的参数；在模拟大气中（例如系统地建立一个场），这些粒子将于2011年3月14日21:10至3月15日9:10在日本图库巴释放，
The role of this study in terms of health physics and radiation protection has been implemented to evaluate the internal dose (relative to the committed equivalent dose) and the dose distribution imaging due to gamma rays (photons) and beta particles emitted from the radioactive Cs-bearing particles in atmospheric aerosol dusts deposited in the lungs via pulmonary inhalation. The PHITS code combined with voxel phantom data (DICOM formats) of human lungs was used. We have dealt with the insoluble radioactive Cs-bearing particles of water (about 2.6 m diameter) migrated onto any of six regions, ET1, ET2, BB, AI-bb, LNET, and LNTH, in a respiratory system until dropping into blood vessels. Source parameters were those of an adult male breathing a typical air volume outdoors; in the simulated atmosphere (such as systematically setting up a field) those particles would be released on 21: 10 March 14 to 9: 10 March 15, 2011 in Tukuba, Japan,
