| description | In the present investigation, a surface-deposited polonium was measured in
37 houses in Rasht and Ramsar cities of Iran with the aim of evaluating the
retrospective radon concentration. The CR-LR technique is widely
used in this regard, but for the first time, Lexan polycarbonate
detectors were used to measure the activity of 210Po planted in glassy
objects. These detectors were placed on glassy surfaces for 153 to 365 days.
A passive cylindrical diffusion chamber was used for the contemporary
radon concentration measurements. The diffusion chamber consists of the
Lexan polycarbonate films as a solid state nuclear track detectors and
filter. The surface-deposited 210Po activity concentration was found to vary
from 0.26 to 11.96 mBqcm-2 with average of 2.62 mBqcm-2. The sensitivity of
210Po to polycarbonate was determined to be 0.06456 track per cm2 per
mBqhcm-2. Thus, the radon concentration was found to vary from 122 to
4840 Bqm-3 with an average value 1243 Bqm-3 and the contemporary radon
concentration in the area was found to vary from 15 to 2420 Bqm-3 with an
average 513 Bqm-3. The results indicate that there is a significant
correlation between the concentration of the retrospective radon and the
concentration of the contemporary radon gas in the indicated areas with a
coefficient of 0.80672. |
