| Abstract: | The present work
deals with the radioactivity of rock samples collected from three towns, one
from each district, of northern region of Karnataka,
India. The
measured mean activity concentrations of 232Th, 238U and 40K
are found to be 73.54, 47.32 and 114.76 for Gadag, 7.2, 4.9 and 121.8 from Gulbarga and 20.96, 42.2
and 875 Kottur samples, respectively. The measured values of dose rate due to
natural radioactivity in the rock samples varied from 11 to 170  Sv/y. This study shows that a basalt rock contains lesser
radioactivity concentration compared to the green schist belt rocks. |
