热释光(简称TL)剂量测量技术是近二十年迅速发展起来的一种新技术.在辐射防护、放射性医学、放射生物学、宇宙医学、考古学、地质学等方面都受到重视,并得到日益广泛的应用.特别是随着现代物理学及测试技术的发展,热释光剂量技术在国外应用于寻找放射性矿床,并在已知铅锌矿床上进行试验,已取得了显著的效果.目前它已成为研究现代地质学的主要手段之一.热释光的一般概念和测量方法热释光系指荧光体受到辐射激发时释放出光的现象.荧光体并不是特殊物质,除金属因导带与价带重叠在一起不能释放荧光外
Thermoluminescence (TL) dose measurement technology is a new technology developed rapidly in recent twenty years, and has received great attention in radiation protection, radiological medicine, radiobiology, cosmology, archeology and geology, etc. Especially with the development of modern physics and testing technology, thermoluminescence dosimetry has been applied abroad in the search for radioactive deposits and has been tested on the known lead-zinc deposits, and remarkable results have been obtained. At present, it has become one of the main means to study modern geology.General concepts and measurement methods of thermoluminescence Thermoluminescence refers to the phenomenon that the phosphor emits light when excited by radiation.The phosphor is not a special substance, Overlapping band with valence band can not release fluorescence
