Explanation

Uranium and thorium are the main atomic minerals which are mostly used in generating nuclear energy. Apart from these two, beryllium lithium and zirconium are other atomic minerals. Although monazite sands which occur in east and west coasts of India have also reserves of uranium. However, the largest concentration of monazite sand is found on the Kerala coast and over 1,50,000 tones of uranium is estimated to be contained in monazite. It is also derived from monazite which contains 10% thorium. It is found along the Kerala coast and in alluvial rocks of Ranchi and Hazaribagh district of Jharkhand.
