While high-energy photon radiation in radiotherapy of deeper tissues has a skin-sparing effect, contamination with electron and low-energy photon radiation can diminish and even abolish this effect. Experiments with perspex, aluminium and copper filters showed that a copper filter effectively diminished the skin dose owing to contaminated radiation.
虽然深部组织放射治疗中的高能光子辐射具有皮肤保护作用，但电子和低能光子辐射的污染会削弱甚至消除这种作用。使用有机玻璃、铝和铜滤过器进行的实验表明，铜滤过器能有效降低因受污染辐射导致的皮肤剂量。
