Residential radon in Galicia: a cross-sectional study in a radon-prone area

Abstract: Residential radon exposure is a major public health problem. It is the second greatest cause of lung cancer, after smoking, and the greatest in never-smokers. This study shows the indoor radon exposure distribution in Galicia and estimates the percentage of dwellings exceeding reference levels. It is based on 3245 residential radon measurements obtained from the Galician Radon Map project and from controls of two previous case-control studies on residential radon and lung cancer. Results show a high median res… Show more

“…Comparison to global radon levels recently compiled by Gaskin et al . 9 (and accounting for other studies 28 ) indicates the 1,313,748 km 2 survey region encompasses one of the most radon-exposed large populations mapped to date (Fig. 1D).…”

“…7 In our series, the median radon concentration was 182 Bq/m 3 , well above the action level of 100 Bq/m 3 recommended by the World Health Organization (WHO), 6 and is also higher than the average radon concentration observed in never-smoker controls who lived in the same area from a previous study by our group (median concentration 149 Bq/m 3 ), 14 or compared with the median concentration of the Galician population, established at 100 Bq/m 3 . 23 Furthermore, the patients included in this case series had lived in the dwelling where the measurements took place for an extended period, a median of 43 years, and this prolonged exposure lends greater validity to potential effect due to high radon exposure. In addition, the majority of SCLC cases included in this series were women, many of them housewives or dedicated to local agricultural labor, and thus, the proportion of daily time spent in the dwelling is higher than it would be if they worked outside the home.…”

“…Accordingly, more studies should analyse this possible increase in COPD prevalence or COPD-related complications among patients with exposure to settings with higher radon concentrations. It should be stressed here that the fact of conducting studies in areas with a high presence of radon, such as Galicia, 28,29 may well facilitate the detection of this association, should it in fact exist. Currently, a case-control study is being undertaken in Galicia to ascertain whether radon may influence the appearance of COPD.…”
