Asses of Indoor Radon Dose and its Risks on children’s Health using Track Detectors: Case Study in Koya Kindergartens


In order to assess effects of long term exposure of radon gas, CR-39NTDs exposed to indoor radon during summer season in the rest halls (ground floor) of 20 selected Kindergartens of the districts of Koya, Iraqi Kurdistan. Ventilation rate affect on the results of indoor radon concentration for each kindergarten. Good ventilation got a low level of indoor radon as measured inside Papula Kindergarten: opposite of that of poor ventilation rate got a high level of indoor radon, as measured inside Hang kindergarten.Average of high value of indoor radon concentration (Bq/.m3), annual effective dose (mSv/y) ,and potential alpha energy concentration (WL) were equal to (45.459±8.546) Bq/.m3,(0.281) mSv/y, and (0.056) mWL, respectively. Results were compared with some international reports and references that used CR- 39NTDs to asses of indoor radon concentration. It was under the levels that mentioned in other references.
