Abstract
A dedicated research since 2001 has revealed that any home stored CD/DVD can serve as a
retrospective radon detector. As a part of an international collaboration, indoor radon was
measured in 18 towns of Republic of Macedonia using the retrospective method of home stored
CDs/DVDs. In the period September - November 2012 totally 67 CDs from ground floors of 54
randomly selected dwellings were collected. In order to investigate the reproducibility of the
results, in 13 dwellings a couple of disks were analyzed. The average disk occupancy (exposure
time) was 12 years (range: 9-22 y). After collection of CDs, they were processed and analyzed in
the Laboratory of Dosimetry and Radiation Protection at University of Sofia. The obtained mean
222Rn concentration ranged within 6 - 541 Bq m-3 with average 75 Bq m-3 and median 52 Bq m-3
(95% CI for the median: 38 - 63 Bq m-3). The distribution of the results was close to log-normal.
The 222Rn concentrations measured in this survey were compared with the results, obtained in
these towns within the National survey, performed in 2008-2009 using CR-39 track detectors.
Both approaches for large scale surveys were compared in terms of organization, duration and
potential for large scale application.
