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.
