Abstract

Radon concentrations in brick samples collected from different countries were measured using the sealed-can technique based on the CR-39 SSNTDs. CR-39 detectors are widely used for radon exhalation rate measurements in bricks under different conditions. The detectors were exposed to standard radon concentration from a standard 226Ra source. The average 222Rn and 226Ra concentrations are found to be 280 Bq m-3 and 1.72 Bq kg-1, respectively. The highest radon exhalation rate was found in Samawah bricks, Iraq. The values of effective radium content are less than the permissible value of 370 Bq kg-1.
