CAS号:

性质:放射性原子核发射α、β、γ等射线的过程。广义上,也可以指例如自发的或人工引起的原子核裂变,高粒子或宇宙射线对原子核的轰击等任何原子核过程中,各种粒子和反粒子(如中子、中微子、反中微子等)的发射。放射性元素在体外对机体有外照射作用;通过呼吸和污染食物进入体内则有内照射作用。过量的外照(射)与内照(射)都会引起放射病。防止人员急性辐射损伤非随机性效应的发生,或减轻其效应,并使远期损伤随机性效应的发生率降低至合理的可接受水平。通常使用各类核辐射剂量探测仪器实施监测。一般利用核辐射的气体电离作用、固体电离作用、荧光作用和化学作用等性质。在工业、农业、医学、环境等领域中有重要应用价值。
