Abstract
Absorbed dose rates in air for 20 residential areas in Odisha were measured using a vehicle-mounted NaI(Tl) scintillation spectrometer. The average values and standard deviations of absorbed dose rate in air for seaside and inland areas were 230 ± 116 nGy h−1 and 123 ± 18 nGy h−1, respectively. The annual external effective dose ranged from 0.43 to 4.59 mSv y−1 with the average value of 1.29 mSv y−1; this indicated there were wide deviations. Analysis of measured data showed that 232Th and 238U were concentrated in the seaside area.
