Abstrakt: As reported in previous studies, Galicia (NW Spain) is an area of high radon concentrations. This study was sought to analyze the correlation between short-term (activated carbon) and long-term (alpha particle track) detectors in this geographic area, and ascertain whether there were differences in their readings that might be influenced by other variables. A comparison study, as part of a case-control study was designed in which two detectors, one of each type, were placed in the selected homes. A total of 391 homes yielded readings with both detectors. The results indicated that there was a relatively good correlation between both types of monitors (correlation coefficient 0.608; p<0.001). The highest correlations between both detectors were observed for unventilated homes, coastal sites, and the oldest buildings. Short-term and long-term detectors do not show a similar performance in all settings or situations. It is advisable to use long-term detectors whenever possible.
