摘要

本研究使用基于 LR-115 II 型固态核轨道探测器的双杯剂量计来估算埃及十个城市三十个住宅环境空气中的氡（222Rn）和钍（220Rn）气体浓度水平。在所研究的住宅中，氡浓度水平从 24.80 ± 3.98 到 39.71 ± 8.71 Bq m-3 不等，平均值为 32.64 ± 4.34 Bq m-3，而钍浓度从 10.46 ± 2.87 到 15.41 ± 2.72 Bq m-3 不等，平均值为 12.48 ± 1.58 Bq m-3。这些住宅的居民每年因氡和钍而受到的总有效剂量低于国际机构建议的限值。本研究的结论是，这些住宅是安全的，不会对人类造成重大的辐射威胁。

A study of radon, thoron and annual effective dose in some Egyptian dwellings by twin-cup dosimeter technique with LR-115 detectors

In the present study, Solid State Nuclear Track Detectors (LR-115–type II) based twin-cup dosimeters were used for estimating radon (222Rn) and thoron (220Rn) gas concentration levels in the environmental air of thirty dwellings in ten cities in Egypt. In the studied dwellings radon concentration levels were found to vary from 24.80 ± 3.98 to 39.71 ± 8.71 Bq m−3 with an average of 32.64 ± 4.34 Bq m−3 whereas thoron concentration is found to vary from 10.46 ± 2.87 to 15.41 ± 2.72 Bq m−3 with an average of 12.48 ± 1.58 Bq m−3. The total annual effective dose by the inhabitants of these dwellings due to radon and thoron was found below the recommended limit by the international agencies. The present study concluded that the dwellings are safe without posing significant radiological threats to human beings.

期刊介绍： Radioprotection publishes articles on all aspects of radiological protection, including non-ionising as well as ionising radiations. Fields of interest range from research, development and theory to operational matters, education and training. The very wide spectrum of its topics includes (theoretical and practical aspects): dosimetry, instrument development, specialized measuring techniques, epidemiology, biological effects (in vivo and in vitro) and risk and environmental impact assessments.
