硅酸锆对于我国陶瓷砖放射性水平的影响

Effect of zirconium silicate on radioactivity level of ceramic tiles in China

采用低本底多道γ能谱仪分别测量未添加硅酸锆和添加硅酸锆的陶瓷砖,比较其放射性水平数据。结果表明,添加硅酸锆的陶瓷砖的放射性水平高于未添加硅酸锆的陶瓷砖。提出通过陶瓷砖工艺的改进,合理、规范地添加硅酸锆,以降低其放射性水平。

The low-background multichannel γ energy spectrometer is used to measure and compare the radioactivity level of ceramic tiles with and without zirconium silicate. The results show that the radioactivity level of ceramic tiles with zirconium silicate is higher than that of ceramic tiles without zirconium silicate. The suggestion to reduce the radioactivity level of ceramic tiles through process improvement and reasonable addition of zirconium silicate is put forward.
