致癌效应在放射病理学上占有重要地位,如遗传效应一样,两者都是评价辐射危险度的依据。辐射致肿瘤作用与辐射种类和条件间的依赖关系是从实验研究中认识的。各种类型放射线,包括结合状态的放射性核素,都可诱发肿瘤,事实上所有的组织器官都可发生肿瘤。放射性核素的一个特征是有强烈的致肿瘤作用。肿瘤的诱发率和产生的类型取决于进入机体的放射性物质的量,形式、进入的途径和节律、能量的吸收和 The carcinogenic effect occupies an important position in the pathology of radiation. Like genetic effects, both are the basis for assessing radiation risks. The dependence of radiation on tumors and the type and condition of radiation is known from experimental studies. Various types of radiation, including radionuclides in combination, can induce tumors. In fact, tumors can occur in all tissues and organs. One feature of radionuclides is their strong oncogenic effect. The rate of tumor induction and the type of production depend on the amount of radioactive material that enters the body, the form, the route and rhythm of entry, the energy absorption, and
