摘要

The objective of the present study was to assess the lung cancer risk induced by exposures to radon progeny of people living in some areas of Transylvania, Romania. Indoor radon concentrations were measured in 667 dwellings of Stei area, Cluj, Bistrita-Nasaud, Sibiu, and Alba counties. Measurements were performed using CR-39 track detectors, exposed for a minimum of 3 mo. Average annual radon concentrations were 232, 114, 71, 62, and 161 Bq m for Stei area, Cluj, Bistrita-Nasaud, Sibiu, and Alba, respectively. The linear risk model of Darby was used to simulate the dose-effect relationship and relative lung cancer risk at low doses of alpha particles specific to residential radon exposures. Predicted relative risks at the measured exposure levels, together with information on the total number of reported lung cancer deaths and the number of people living in these regions, enabled us to estimate the fraction of lung cancer cases in each area that is attributable to radon. These percentages are 16.67% for Stei area, 9.09% for Cluj, 5.66% for Bistrita-Nasaud, 4.76% for Sibiu, and 12.28% for Alba county among lifetime non-smokers. Assuming that the smoking rates are similar for the investigated regions (10.72% smokers among men and 5.95% among women), around 64 to 69% of the total number of annual lung cancer deaths, stratified by sex, would be attributed to radon and occur among smoking male population, and around 35 to 44% would be attributed to radon and occur among smoking female population.
