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
