摘要

利用固态核径迹探测器技术，在印度哈里亚纳邦西部地区20个村庄的100个住宅中进行了室内氡研究。LR-115型II型胶片在裸照模式下每季度曝光一年，以覆盖所有四个季节，以测量室内氡水平。研究区室内氡年平均浓度为126 ~ 546 Bq∙m−3，平均值为252 Bq∙m−3。室内氡的季节变化表现为冬季较高，夏季较低。终生死亡风险评估和研究地区居民接受的年平均剂量也被计算为在每年3-10毫西弗的建议安全限度之内。因此，由于住宅中存在天然氡，对居民没有重大威胁。

Measurement of indoor radon concentration in the dwellings of Western Haryana, India, for health risk assessment

Indoor radon studies have been carried out in 100 dwellings of 20 villages in western districts of Haryana, India, using the solid-state nuclear track detector technique. LR-115 Type II films in the bare mode were exposed for 1 year on a quarterly basis to cover all the four seasons for the measurement of indoor radon levels. The annual average indoor radon concentration in the study area varies from 126 to 546 Bq∙m −3 , with an average value of 252 Bq∙m −3 . Seasonal variation of indoor radon shows higher values in winter and lower values in summer. Lifetime fatality risk assessment and annual average dose received by the residents of the study area are also calculated to be within the recommended safe limit of 3–10 mSv per year. Hence, there is no significant threat to the residents due to presence of natural radon in the dwellings.
