Publication Abstract: 

Seasonal (winter-summer) indoor and soil radon comparison is made in two villages in Najran region,

south west of Saudi Arabia, using CR-39 Dosimeter. Summer indoor radon concentrations were measured

in the villages of Fara Al-Jabal and Hadadah. The respective winter-summer average values of

42 ± 4 Bq m3 and 74 ± 5 Bq m3 are measured in Fara Al-Jable village and the average values of

47 ± 4 Bq m3 and 76 ± 5 Bq m3 are measured in Hadadah village. The respective winter-summer soil

values are 1.40 ± 0.21 kBq m3 and 0.99 ± 0.04 kBq m3 in Fara Al-Jabal village while those measured in

Hadadah village are 2.90 ± 0.17 kBq m3 and 1.40 ± 0.66 kBq m3. Indoor radon levels are found to be

seasonal dependent while that of soil are found seasonal and location dependent. Meteorological and

geological factors are expected to have caused the measured significant differences in radon levels in

dwellings and soil in the two villages.
