ABSTRACT: For years there has been an important concern and interest in the scientific community due to exposure to high levels of Rn inside homes, work centers and schools. This concern is spreading to the whole population and there are numerous references in press articles and media to this noble gas. It is well known that people who inhale high concentrations of radon have a higher risk of developing lung cancer, which is induced by the descendants of the inhaled gas. In this study, we present the most relevant data obtained in a single-family house in which the owners suspected of being subjected to high concentrations of radon. To carry out the study we used active systems, specifically 6 devices with diffusion chamber and silicon diode, Alpha E model of Saphimo and also an AlphaGuard 2000 Pro equipment. We also used passive systems using active carbon cartridges for measurements in gamma spectrometry equipment. The site of study was a house of 1550 m2 distributed in two modules with two heights and basement conditioned as service housing. After an initial evaluation in the whole house, we detected high levels of radon in three rooms of the house, registering average values higher than 600 Bq m-3 in one of them, with a maximum value of 12535 Bq m-3 registered in an area not inhabited of the house. Corrective measures were carried out using waterproofing materials and forced extraction systems in the uninhabited area of the basement, reducing radon levels below 100 Bq m-3 as a mean value.

KEY WORDS: radon, diagnosis, remediation measures, house.
