MEASUREMENT OF INDOOR RADON CONCENTRATIONS IN ALTAHSEENYAH AND KUT AL-HIJAJ REGIONS IN BASRA GOVERNORATE USING SSNTDS DETECTORSARKAN Y. YOUSIF, JABBAR H. JEBUR AND RUSUL I. NOORIAbstract 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 24±6 Bq/m3 to 34±8 Bq/m3 andfrom 4±1 Bq/m3 to 20±5 Bq/m3 for ground and first floor levels respectively belongs to Al-Tahseenyah selected houses. For Kut Al-Hijaj region, the results ranged from 24±5 Bq/m3 to 28±7 Bq/m3 and from 6±1Bq/m3 to19±5 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. |
