Abstract:
The present study was carried out to determine the distribution of radon (222Rn) activity concentration
measured using Durridge RAD-7 in the groundwater samples in the coastal area of Baleshwar district,
Odisha, India. The 222Rn activities in 10 groundwater samples of coastal area of Baleshwar were measured
and the values of 222Rn ranged between 1.6 0.21 and 17.0 1.69 kBqm 3 with an average value
of 8.98 0.85 kBqm 3, and seven samples were well within the Environmental Protection Agency’s
maximum contaminant level of 11.1 kBqm 3 while three samples were more than the maximum contaminant
level of 11.1 kBqm 3. The effective dose per m3 and annual effective dose values were varying
with respect to the increase in radon concentration and were significantly lower than the United
Nations Scientific Committee on the Effects of Atomic Radiation and WHO recommended limit for
members of the public of 1mSvy
