Abstract

The gamma dose rates in rural and urban areas of Durg were compared. The statistical study was made to compare the outdoor and indoor gamma dose rates for the rural and urban areas. The lifetime effective doses for the rural and urban areas were found to be from 64.4 ± 2.6 to 105.4 ± 4.2 and from 82.2 ± 3.3 to 92.9 ± 3.7 mSv, respectively. The excess lifetime cancer risk ranging from 5.2 × 10^–3 to 5.3 × 10^–3 was found in several rural areas. The maximum values of the indoor gamma dose rate observed in the rural and urban areas are 253 ± 10 and 224 ± 9 nSv/h, respectively, which is higher than the typical range (10–200 nSv/h) reported by UNSCEAR. The measured gamma dose rate for terrestrial is compared to the reported values of radiation near uranium mines in India and in the world. The effective organ dose is higher than the recommended limit of 1.0 mSv/year.

印度恰蒂斯加尔邦Durg区城乡地区伽玛剂量率和相关风险评估的统计比较研究

摘要

比较了杜尔格农村和城市地区的伽马剂量率。进行了统计研究，以比较农村和城市地区的室外和室内伽玛剂量率。发现农村和城市地区的终生有效剂量分别为64.4±2.6至105.4±4.2和82.2±3.3至92.9±3.7 mSv。终生癌症额外风险从5.2×10 ^–3到5.3×10 ^–3被发现在几个农村地区。在农村和城市地区观察到的室内伽马剂量率最大值分别为253±10和224±9 nSv / h，高于UNSCEAR报告的典型范围（10-200 nSv / h）。将测得的地面伽马剂量率与印度和全世界铀矿附近的报道辐射值进行比较。有效器官剂量高于1.0 mSv /年的建议限值。
