摘要

Terrestrial gamma radiation is one of the important radiation exposures on the Earth's surface that results primarily from the three primordial radionuclides, viz. U, Th and K. The elemental concentrations of these elements in the Earth's crust could result in the anomalous variation of the terrestrial gamma radiation in the environment. The geology of a region plays an important role in distribution of these radioactive elements. In situ gamma radiation measurements in the soils and adjacent rock exposures along the Singhbhum Shear Zone, Eastern India were undertaken using a portable radiation survey meter. The results showed that the area has a reasonably close concordance with the geological formations, and the observed gamma radiation levels, since both geological features and mineralogical composition have good control on the terrestrial gamma radiation in the area. Correlation between the gamma level of soils and the underlying rocks was very poor. This suggests that the soils might not have originated from underlying rocks or might have different weathering mechanisms.
