一、辐射致癌危险估计模型辐射致癌危险估计的成果被用于辐射健康有关的社会实践中的两个管理领域:一是为辐射防护制定剂量限值提供生物学证据,二是为职业赔偿计算病因概率(PC)提供模型和参数。辐射致癌危险估计用辐射致癌系数(又称为危险度)来表示:绝对危险(AR)系数是单位剂量照射引起的癌症增加,亦即实际观察数(Obs)与该人群预期发生数(Exp)之差;相对危险(RR)系数是观察数与预期数之比(Obs/Exp),通常使用相
I. RADIOGENOUS CANCER HAZARDS ESTIMATION MODEL The results of the radiation carcinogenicity risk assessment are used in two management areas in radiation health related social practice: one is to provide biological evidence of dose limits for radiation protection and the other is to calculate the cause of compensation for occupational compensation Probability (PC) provides models and parameters. Radiation Oncogenic Risk Estimation Using radiation-induced carcinogenesis (also known as risk), the absolute risk (AR) factor is the increase in cancer caused by unit dose irradiation, ie, the actual observed number (Obs) The relative risk (RR) coefficient is the ratio of the number of observations to the expected number (Obs / Exp), usually using the phase
