The paper presents the distribution of natural radionuclides in soils with various clay minerals of Davanagere district. The activity concentration of natural radionuclides in soil were measured using NaI(TI) gamma spectrometry and the minerals present in the soils were identified using Fourier–transform infrared spectroscopy. The normality of the frequency distribution curve of 226Ra, 232Th and 40K concentration was verified using Kolmogorov–Smirnov test. The major trace minerals observed in the soils were determined based on the intensity of corresponding peaks. The soil with clay minerals Quartz and Hematite showed higher radionuclide content.

印度卡纳塔克邦 Davanagere 地区自然放射性对土壤粘土矿物依赖性的研究

本文介绍了天然放射性核素在 Davanagere 地区具有各种粘土矿物的土壤中的分布情况。使用 NaI(TI) 伽马光谱法测量土壤中天然放射性核素的活性浓度,并使用傅立叶变换红外光谱法鉴定土壤中存在的矿物质。使用 Kolmogorov-Smirnov 检验验证了226 Ra、232 Th 和40 K 浓度的频率分布曲线的正态性。土壤中观察到的主要微量矿物质是根据相应峰的强度确定的。含有粘土矿物石英和赤铁矿的土壤显示出较高的放射性核素含量。
