Abstract This paper presents the results of measurement of natural and fallout radioactivity in soil samples of
Chamba and Dharamshala areas in Himachal Pradesh,
India. Spatial distribution of 238U, 226Ra, 232Th, 40K, 137Cs was determined using High resolution gamma-ray spectrometry.
The mean activity concentration in Chamba region due to 238U, 232Th, 40K and 137Cs was 32.3, 58.4,
588.3, and 10.9 Bq kg-1, respectively, whereas in Dharamshala it was 35.7, 61.3, 594.9, 10.0 Bq kg-1, respectively.
Absorbed gamma dose rate (D) in air was calculated using appropriate dose
