| 摘 要： | 具有较高能量的射线照射物质时,被物质吸收,使其内部组成、结构和性质发生变化。被照物质的变化可以归结为三种效应:物理效应、化学效应和生物效应。研究三种效应的规律应用于科研和生产中,从而发展起来的一门新兴技术即辐射应用技术。

| Abstract: | When the substance was irradiated with higher energy particles (charged weight particles, energetic electron,electronmagnetism radiation and neutron) , the rays were absorbed by substance.The com position, construction and properties of the substance were changed.The mutual action process between the radiation and substance include photoelectric effect,Compton effect and electron pair produce.The action process between the radiation and substance include inelastic colli-sion, elastic collision and hremsstrahlung The change of irradiated substance sumup the three effects: physics, chemical and bioligy effects. |
