摘要

报道了对西安建材市场23种饰面瓷砖中天然放射性核素含量的调查与测量结果，并按照国家有关建筑材料放射性核素限量标准进行了分类。分析结果表明，饰面瓷砖中天然放射性核素铀、镭、钍、钾含量处于正常本底水平，其中铀、镭、钍、钾比活度的范围为：,238,U (17.6—82.5)Bq•kg,-1,；,226,Ra (24.1—182)Bq•kg,-1,；,232,Th(13.4—75.7)Bq•kg,-1,；,40,K(112—506)Bq•kg,-1,。根据最新国家标准(GB6566-2001)的分类要求，所测饰面瓷砖均属A类产品，应用范围不受限制。

Abstract

This paper reports investigation results on natural radioactive nuclide contents of facing tile products from Xi’An construction market, and the products has been classified according to the national standard. The results show that natural radioactive nuclide contents in sampled facing tile products are in normal radioactive background level. The radio-activity ranges of U-238, Ra-226, Th-232 and K-40 are 17.6—82.5, 24.1—182, 13.4—75.7, 92.1—506Bq•kg,-1, respectively. According to National Standard JC518-93, these tiles belong to A grade products and applications of the products shall not be limited.
