摘要: Abstract In the present work, we used (CR–LR) difference technique for retrospective radon progeny measurements in 17 dwellings based on implanted 210 Po activities glass objects. A total of 48 objects were examined, but only 19 gave results which sufficiently reliable due to sensitivity method. From these data, an increase surface with age was noticeable as expected. The then converted potential alpha energy concentration (PAEC) through a calibration curve. It found that PAEC dwelling sites did not change significantly building age.
