本项目使用固体径迹蚀刻法、BH1936低本底多道γ能谱仪对河北省沧州市南皮县某村庄两个传统的蔬菜温室大棚和南华大学某现代化玻璃大棚内的放射性水平进行测量。结果显示,三个大棚平均氡浓度分别为136、89、8.8 Bq/m^3。前两个大棚土壤中^40K、^232Th、^226Ra三种放射性核素的比活度较为正常,但空气中氡浓度偏高。作业人员年均有效剂量分别为1.27、1.13、0.94 m Sv/a。有效通风可以显著降低大棚中氡浓度,保障作业人员的身体健康。

In this paper, the CR-39 SSNTD solid track detector box dosimeter and BH1936 low background multi-channel γ spectrometer were used to measure radioactivity level in the two traditional vegetable greenhouses in Cangzhou, Hebei Province and a modern glass greenhouse in University of South China. The results show that the average radon concentrations in the three greenhouses are 136 Bq/m 3 , 89 Bq/m 3 , 8.8 Bq/m 3 , respectively. The specific activities of 40 K, 232 Th and 226 Ra in the soil of the first two are high, and the average effective do...
