Measurement of Indoor Radon Concentration in Dwellings of Koya Using Nuclear Track Detectors
Journal Title: UNKNOWN - Year 2015, Vol 4, Issue 1
Abstract
Exposure to natural sources of radiation, especially 222Rn and its short-lived daughter products has become an important issue throughout the world because sustained exposure of humans to indoor radon may cause lung cancer. Therefore, indoor radon concentration has been measured 42 homes of Koya in Erbil, Iraqi Kurdistan. CR-39 (NTDs) nuclear track detectors were exposed for 60 days for the measurement of indoor radon levels. The average indoor radon concentration have been measured which are found to be in the range 22.45 ± 1.86 to 75.84 ± 3.75 Bq/m3. The mean annual estimated effective dose received by the residents of the studied area was estimated to be 1.24 mSv. The annual estimated effective dose is less than the recommended action level (3-10 mSv).
