Abstract

Natural radioactivity measurement, radiation monitoring of the region, dose assessment and interpretation of radiological-related parameters are crucial aspects from the public awareness and environmental safety point of view. The ionising radiations (gamma-rays) emitted from radionuclides such as 226Ra, 232Th and 40K present in environmental materials contributes significantly to the external radiation dose received by the public. High-efficiency gamma spectrometry based on a 4″ × 4″ NaI (Tl) detector was employed for estimating activity concentrations of the gamma-emitting radioelements. The spectra from the detector were recorded using a PC-based 1k multichannel analyser system (WinTMCA 32). Each sample spectrum was acquired for a counting period of 60 000 s (16.67 hr). Assuming the daughter products of 226Ra and 232Th in equilibrium, the activity concentration of these radionuclides were estimated by using the prominent gamma photo peaks of daughter products. Using the same technique, dose-related radiological parameters were calculated for all the samples. The activity concentrations of the radionuclides and the dose-related parameters for the samples were found to be comparable with the global literature values. The data generated from our study will contribute to the baseline radiological data of the region.

印度卡纳塔克邦 Bidar 地区土壤样本中天然放射性水平的测量。

从公众意识和环境安全的角度来看，天然放射性测量、区域辐射监测、剂量评估和辐射相关参数的解释都是至关重要的方面。环境材料中存在的 226Ra、232Th 和 40K 等放射性核素发出的电离辐射（伽马射线）在很大程度上增加了公众受到的外部辐射剂量。我们采用了基于 4″ × 4″ NaI (Tl) 探测器的高效伽马能谱仪来估算伽马放射性元素的放射性活度浓度。检测器的光谱是用一个基于 PC 的 1k 多通道分析仪系统（WinTMCA 32）记录的。每个样品的光谱都是在 60 000 秒（16.67 小时）的计数时间内获得的。假設 226Ra 和 232Th 的子產物處於平衡狀態，我們便利用子產物的顯著伽馬光峰來推算這些放射性核素的放射性活度濃度。用同样的方法计算了所有样品的剂量相关辐射参数。结果发现，样本的放射性核素活度浓度和剂量相关参数与全球文献值相当。我们研究得出的数据将为该地区的基准辐射数据做出贡献。

期刊介绍： Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
