辐射致癌危险预测模型的改进
Improvement of the projection models for radiogenic cancer risk
-
摘要: 对辐射致癌危险度的计算,是基于特定肿瘤的危险预测模型。最近,对原有模型中使用的一些参数进行了改进,包括采用两种危险系数即死亡率危险系数和发病率危险系数、提出年龄和性别特异性的致癌危险系数等。应用这些改进的危险系数,计算并给出了不同核素和不同暴露方式下组织和器官的辐射致癌危险度估计值。Abstract: Calculations of radiogenic cancer risk are based on the risk projection models for specific cancer sites. Improvement has been made for the parameters used in the previous models including introduc-tions of mortality and morbidity risk coefficients, and age-/gender-specific risk coefficients. These coeffi-cients have been applied to calculate the radiogenic cancer risks for specific organs and radionuclides under different exposure scenarios.
