A SURVEY OF RADON LEVELS IN JORDANIAN DWELLINGS DURING AN AUTUMN SEASON

Previously calibrated dosemeters containing CR-39 plastic detectors we re used to measure radon levels in Jordanian cities during the autumn. The averages of radon concentrations in the different cities obtained in this work range from 29.3 to 99.7 Bq.m(-3). It was found that the city of Karak possesses the highest radon concentrations and the city of Aqaba possesses the lowest. Thus, the calculated average radon leve ls in Jordanian dwellings as a whole was found to be 56.7 Bq.m(-3). Th e average radon induced lung cancer risk during a lifetime for dweller s of the cities under study was found to range from 0.12% to 0.41%.
