| Abstract: |
The radon and its progeny concentrations are
measured near the surface of the earth at the Indian Institute of Tropical
Meteorology, Pune, India. In-situ measurements of the meteorological parameters such as
temperature and relative humidity are also made simultaneously. The
concentrations show maxima in the early morning hours when the turbulence
mixing is the minimum; whereas in the afternoon the turbulence mixing is the
maximum and concentrations exhibit minima. The diurnal and seasonal variations
in the concentrations of radon and its progeny are found to exhibit correlation
with the relative humidity, and anti-correlation with the temperature. The
annual effective dose for Pune environment is found to be 0.55 mSv which is
within the permissible limit.
