摘要：

A national survey on indoor radon levels in Spain has been carried out by measuring the radon concentration in 1555 randomly chosen houses. Measurements were performed during the winter season of 1988 with complementary measurements in the winter of 1989. Radon in air was determined using modified alpha-scintillation cells under specified conditions in the sampling collection and nuclear track detectors in selected houses. The distribution of indoor radon levels has been found to be approximately log-normal with a geometric mean of 41.1 Bq.m-3 and a standard deviation of 3.0. The highest value of the radon concentration found was 15 400 Bq.m-3 In about 4% of the houses, the radon concentration was found to be in excess of the recently recommended value of 400 Bq.m-3, suggested by the Commission of the European Communities (CEC). Elevated indoor levels were found to be more prevalent in the west and northwest than in the rest of the country. Also shown in this paper is an evaluation of the median effective dose equivalent to the individual in Spanish houses for different regions.
