所谓个人剂量限值,是指受控源计划照射使个人所受到的有效剂量或剂量当量不得超过的值。放射防护体系中,正当性和防护最优化两项原则是源相关的,适用于所有照射情景,个人剂量限值是个人相关的,仅适用于实践或者称为计划照射的情形。从1895年伦琴发现X射线不久,就出现了放射损伤
The so-called personal dose limits, refers to the controlled source of exposure so that individuals receive effective dose or dose equivalent value shall not exceed. The two principles of legitimacy and protection optimization in a radiological protection system are source dependent and applicable to all exposure scenarios. Individual dose limits are personal and applicable only to practice or to situations where exposure is planned. Radiation damage occurred shortly after Roentgen discovered X-rays in 1895
