Abstract
The inhaling of indoor radon gas have been well known as the most important health risks all over the world. In the current study, series of measurements deals with this gas were done in groups of homes in two regions located in Basra governorate center (Al-Tahseenyah and Kut Al- Hijaj). The CR39 nuclear track detector has been employed in cup technique to evaluate track density of alpha radiation which is emitted by the gas and its progeny. Measurements were started at the first of March and ended at the last of May. Results obtained varied from 24ñ6 Bq/m3 to 34ñ8 Bq/m3 andfrom 4ñ1 Bq/m3 to 20ñ5 Bq/m3 for ground and first floor levels respectively belongs to Al-Tahseenyah selected houses. For Kut Al-Hijaj region, the results ranged from 24ñ5 Bq/m3 to 28ñ7 Bq/m3 and from 6ñ1Bq/m3 to19ñ5 Bq/m3 for ground and first floors respectively. Data extracted shows that ground floors have higher radon concentrations with respect to first floors for all houses investigated.
