INDOOR RADON CONCENTRATION MEASUREMENTS OF THE NARANI HALL (SOUTH) IN MEIKTILA UNIVERSITY BY USING SOLID STATE NUCLEAR TRACK DETECTORS
Abstract
- A study of indoor radon concentration has been carried out in the three rooms of Narani Hall (south) in Meiktila University Campus, Meiktila Township, Mandalay Region in Myanmar, using LR-115 Type II Solid State Nuclear Track Detectors (SSNTDs). Three small pieces of LR-115 (1cm*1cm) detectors each was attached on the ceiling 9 ft from the floor of the room.According to the present measurements, it was found that, the value of concentration of radon ranges from 25.12 ± 3.39 Bq m-3 to 53.63 ± 11.76 Bq m-3 with an average value of 35.75 ± 6.98Bq m-3. The annual effective dose ranges from 0.43 ± 0.044 m Sv yr-1 to 0.92 ± 0.074 m Sv yr-1 with an average value of 0.61 ± 0.045 m Sv yr-1.
