摘　　要：针对日本福岛事故中放射性铯可能对我国水产品造成的核污染,本文对国内外放射性铯的检测方法进行了整理分析,介绍了目前检测水产品中放射性铯最常见的两种方法:直接γ能谱法和β射线计数法。对比总结了两种测量方法在检测原理、前处理过程、灵敏度、安全性等方面的差异,这对针对不同检测环境及样品中放射性铯检测方法的选择以及未来开发快速、高效的检测方法具有重要的指导意义。Aimed at the possible pollution of radio cesium on aquatic products following Fukushima accident, the methods to detect radio cesium at home and abroad were summarized and analyzed.Of which, the most popular methods including gamma-ray spectroscopy method and beta-ray counting method were introduced. The differences of the two methods in detect mechanism, pretreatment process, sensitivity and security were compared,which will be of great importance not only to choose the proper test method according to different environment and samples,but also establish a rapid and simple method for cesium detection in future.
