VARIATION OF RADON CONCENTRATION IN DIFFERENT SITES IN SYRIAN TYPICALHOUSES

The concentrations of radon and radon daughters in Syrian homes were s tudied since 1994 (Othman et al., 1996). In this work too,the relation ship between the parameters of some houses in Damascus city and radon together with radon daughters concentration were studied. These houses were classified into three types depending mainly on the house design . The radon concentration measurements were carried out in different p laces inside these houses using solid state nuclear track detectors. I n addition a gamma survey meter was used to determine gamma dose rates inside the studied houses and they were compared with radon concentra tions. Scintillation technique was used to monitor the variation of ra don and radon daughter concentrations during the day inside one type o f houses. The correlation between radon concentrations and age of hous es in Damascus city was also checked in this study.
