Abstract
<p>Exposure to radon and radon decay products in the home and at work constitutes one of the most important riskfrom ionizing radiation. Radon is continually produced from uranium and thorium, which occurs in most rocks andsoils, present all over the world.This thesis provides information of physical and chemical properties of radon, it's formation and methods usedfor measuring radon concentration .This study was in some places in Bethlehem Province where the radon levels measured by using CR-39 thatdistributed for different periods , between 245 and 250 detector were distributed but only 159 of them werecollected , half of these detectors were distributed in Al- Obaidiya town , 50.3% of collected detectors related tohouses and schools in Al- Obaidiya , the average radon concentration was. 15.7% of collected detectors was fromAl-Shawawra village with average radon concentration. 6.2% of collected detectors was from Za'atra village withaverage radon concentration 164.6 Bq/m3 . the average radon concentration in Bethlehem and Biet-Shour cities was129.2 and 150 respectively.The study shows a relation between high levels of radon and ventilation , since storages and closed places have highradon concentrations.</p>
