Abstract
Radon emanation has been studied in different rooms of buildings in Ma rrakech by using LR-115 and CR-39 solid state nuclear track detectors (SSNTD). A new calibration method has been developed based on calculat ing the probability for an emitted alpha-particle to be registered on a SSNTD. The thoron-to-radon ratios as well as thoron and radon activi ty concentrations in the dwellings studied have been determined by exp loiting the measured track densities, due to the alpha-particles emitt ed by radon, thoron and their daughters, registered on the SSNTD. The influences of building materials, pollution and painting layers and pa pers were also investigated. Copyright (C) 1997 Elsevier Science Ltd
