Radon retrospective dosimetry in different environments

In the present study of retrospective dosimetry, measurements or Radon ( 222 Rn) and Polonium ( 210 Po) were performed. Radon is a radioactive gas and is concentrated in the interior of residential buildings and working places and is considered as a primary cause of lung cancer. To evaluate measurements in different environments, alpha spectrometry was employed in estimating exposure to radon in various locations over a long period of time (hence, the use of the term “retrospective”) through exposure of plastic and glass surfaces. Following these measurements, the Conversion Factor (CF) was calculated. This factor correlates the measured surface concentrations of 210 Po with the 222 Rn concentrations in the environments under study.
