Abstract
|
|
|
Radon exhalation rates have been determined for samples of concrete, gypsum board, marble, and tile among building
materials that are used in domestic construction environment. Radon emanation was measured using the closed chamber
method based on CR-39 nuclear track detectors. The radon concentrations in apartments of 100 households in Seoul, Busan and Gyeonggi Provinces were measured to verify the prediction model of indoor radon concentration. The results obtained by the four samples showed the largest radon exhalation rate of 0.34314 Bq/m2
·h for sample concrete. The radon concentration contribution to indoor radon in the house due to exhalation from the concrete was 31.006 ± 7.529 Bq/m3. The difference between the prediction concentration and actual measured concentration was believed to be due to the uncertainty resulting from the model implementation.
