Abstract:
The activity concentrations of natural radionuclides 226Ra, 232Th and 40K in soil samples collected from Sijua Dhanbad, India were measured by using a gamma-ray spectrometer with a NaI(Tl) detector. The average activity concentration of 226Ra, 232Th, and 40K was found as 60.3, 64.5 and 481.0 , respectively. Average radium equivalent activity, absorbed dose rate, outdoor dose, external hazard index and internal hazard index for the area under study is determined as 189.5 , 87.2 , 0.4, 0.5 and 0.6 , respectively. The annual effective dose to the general public is found 0.4 . This value lies well below the limit of 1 . Measured values have found safe for the environment and public health of the study area.
