210 Po 、210Bi 和210 Pb 测试技术研究进展与现状

摘要

The detection of uranium series nuclides - 210 Po ,210 Bi and 210 Pb is significant in many fields , such as uranium geology and exploration ,the safe disposal of nuclear waste ,deposition geochronology , isotope geochemistry ,the atmospheric environmental science ,the radiation hygiene .This article sum-marized the research progress and situation of different techniques for measuring 210 Po ,210 Bi ,210 Pb in re-cent years .The major technical problems and the developing future trend was eviewed .%铀系核素210 Po 、210 Bi 和210 Pb 的测试在铀矿地质勘查与核废物安全处置研究、沉积年代学与同位素地球化学研究、大气环境学与辐射卫生学研究等诸多领域具有重要意义。本文重点总结了近些年来210 Pb 、210 Bi 和210 Po 3核素各种测试技术的研究进展与现状，评述了存在的主要问题及未来发展趋势。
