Measurements of the radon-222 and its daughters concentrations throughout Gaza strip, Palestine

High Radon levels are present in the granite and grandiositic rocks that spread in sand dunes along coast of Gaza. Such materials are rich in uranium and widely used in the construction of dwelling in the Ga? ca, and their contribution to high indoor Radon levels is most relevant. The present work aims to investigate approaches, measures and detection of indoor Radon level throughout Gaza Strip. Five hundred CR-39 dosimeters were distributed over six locations in the middle region of Gaza Strip. Results suggest that Radon concentrations range froml3. 36 to 83.82 Bq/m3 and a maximum value of 97.01 Bq/m3. The average Radon concentrations was 37.83 Bq/m3 with standard deviation of 11.23. The results provide a framework for future studies that include a large, broader survey of Radon concentration in Palestin
