Abstract

The activity concentrations of naturally occurring (²²⁶Ra, ²³²Th, ⁴⁰K, ²¹⁰Pb, ²¹⁰Po) and anthropogenic (¹³⁷Cs) radioisotopes were analysed in agricultural and non-agricultural soils in the vicinity of the nuclear facilities at Kalpakkam, India. Outdoor gamma absorbed dose rates were measured at 158 locations using a portable gamma dosimeter. Soil samples from 126 locations were analysed for individual radionuclide activities by gamma and alpha spectrometry. Statistical analysis of the data confirmed no significant difference in the concentrations of ⁴⁰K, ²³²Th, ²²⁶Ra, and ²¹⁰Po between the agricultural and non-agricultural soil types, while ²¹⁰Pb levels differed significantly. The ¹³⁷C activity in all the soil samples was < 0.1 Bq kg⁻¹, confirming that this radioisotope is not released to the environment from the operating nuclear facilities.

印度Kalpakkam核设施15公里范围内农业和非农业土壤放射性核素浓度研究

分析了印度Kalpakkam核设施附近农业和非农业土壤中天然（226Ra, 232Th, 40K, 210Pb, 210Po）和人为（137Cs）放射性同位素的活度浓度。在158个地点使用便携式伽马剂量计测量了室外伽马吸收剂量率。对126个地点的土壤样本进行了伽马和α光谱分析，以确定放射性核素的活性。经统计分析，40K、232Th、226Ra和210Po在农业与非农业土壤类型间的浓度差异不显著，而210Pb含量差异显著。所有土壤样品中的137C活度为0.1 Bq kg−1，证实这种放射性同位素不会从运行中的核设施释放到环境中。
