Abstract
The paper presents the results of high resolution gamma-spectrometric measurements of 137Cs, 40K, 232Th and 238U in Indian soils collected from 24 different places from normal natural radiation background areas. The depth profile of 137Cs was studied at sampling sites. The paper also presents 137Cs levels in top soil at Mumbai during 1986 to 2000. The results in Mumbai soil indicate clearly the accumulation from fallout only on the top soil and seasonal peaking during the beginning of the monsoon season.
