Regional surveys were conducted to determine exposure to natural sources of radiation for people in the vicinity of old Spanish uranium mines. The surveys evaluated indoor radon concentrations and outdoor and indoor external gamma dose rates. Indoor radon concentrations were measured in 222 dwellings by means of nuclear track-etched detectors. The terrestrial gamma ray dose rate was measured outdoors and indoors at a total of 256 points and 115 points, respectively. Estimates mean annual effective doses for the six areas studied ranged from 3.2 to 5.1 mSv per year, which is between 1.2 and 2 times higher than the average national value.
开展了区域调查，以确定西班牙旧铀矿附近居民受到天然辐射源照射的情况。这些调查评估了室内氡浓度以及室外和室内的外照射伽马剂量率。使用核径迹蚀刻探测器在222处住宅中测量了室内氡浓度。分别在总共256个点和115个点测量了室外和室内的陆地伽马射线剂量率。所研究的六个区域的年平均有效剂量估计值在每年3.2至5.1毫希沃特之间，比全国平均值高出1.2至2倍。
