用生物学指标估算辐射剂量,近年来已取得长足进展.虽然淋巴细胞染色体分析仍是主要手段,但它已不再是唯一的定量分析手段.最好的办法似乎是联用多种分析方法,取各自之长:如染色体分析的高灵敏性(低LET,剂量可小至0.05Gy);电子自旋共振技术覆盖的宽剂量区(0.5～100Gy);用毛发直径判定身体局部照射的具体部位等.
The use of biological indicators to estimate radiation dose has made great strides in recent years.Although lymphocyte chromosome analysis is still the main method, it is no longer the only means of quantitative analysis.The best approach seems to be the combination of multiple methods of analysis, Take the respective length: such as the high sensitivity of chromosome analysis (low LET, the dose can be as small as 0.05Gy); electron spin resonance technology covering the wide dose area (0.5 ~ 100Gy); with the hair diameter to determine the specific body parts of the site of irradiation Wait.
