Abstract:
Objective To study gross α and gross β radioactivity in environmental samples in Wuxi, China, and perfect the radioactivity data, and to discover possible radioactive contamination in time. Methods The BH1227 low-background α and β measuring instrument was used to determine gross α and gross β radioactivity in sedimentary dust, aerosol, drinking water, and food samples in Wuxi. Results Among environmental samples collected in Wuxi, 2014—2019, the mean gross α and gross β radioactivity levels were 0.01～5.98 Bq/kg and 9.47～547.86 Bq/kg in food samples, respectively, 1.2～22 mBq/L and 0.1～141 mBq/L in water samples, respectively, 39～44790 mBq/m3 and 743.1～101500 mBq/m3 in sedimentary dust samples, respectively, and 50～1125 μBq/m3 and 38～9510 μBq/m3 in aerosol samples, respectively. Conclusion We should strengthen radioactivity monitoring of environmental samples in Wuxi through increasing the scope and frequency of monitoring, to perfect baseline radioactivity data of Wuxi.
