Description
The present work was attempted to measure the estimation of the annual effective dose of
indoor radon in Department of Physics, Yangon University of Education. Many techniques
have been established for measuring the radiation in the environment. These techniques
are based on the detection of emissions from the decay of radioactive material and its
daughter products. Most of the methods are based on the detection of alpha particles, some
on detection of beta emission while a few utilize gamma decays. In this research, time
integrated long term radon measurement technique is used to measure radon concentration
in the samples under investigation. For the measurement of radon concentration, we have
used LR-115, Type II plastic track detector and irradiation time is 100 days, from 26th
April 2017 to 3rd August 2017. The annual effective doses due to radon are ranging
from 0.07 ± 0.0341 mSv/yr to 0.33 ± 0.0626 mSv/yr which are lower than 5 mSv/yr,
the annual effective doses fixed for public (ICRP,2007).
