估算人体内照射剂量最准确的方法莫过于直接测定人体内各组织和器官中核素的比活度。但是由于人体样品取样困难,分析繁杂,我国人体内放射性核素的数据较少。本文使用~(209)Po示踪α谱法分析了若干中国人骨、人肺和肌肉中~(210)Pb和~(210)Po的浓度并进行了剂量估算。一、取样和分析方法1.取样全部人体组织和器官样品采自
The most accurate way to estimate the amount of radiation in a human body is to directly measure the specific activity of the nuclides in various tissues and organs of the human body. However, due to the difficulty of sampling the human body samples and the complicated analysis, the data of the radionuclides in the human body in our country are few. The concentration of ~ (210) Pb and ~ (210) Po in bones, human lungs and muscles of several Chinese were analyzed by ~ (209) Po tracer a-spectrometry and the dose was estimated. First, the sampling and analysis methods 1. Sampling All human tissue and organ samples were taken from
