Atomic energy can be produced by fission or fusion of the atoms or rather the nuclear parts of radio-active minerals like uranium thorium and radium. India possesses the world’s largest reserves of monazite, the principal source of thorium and some reserves of uranium.
In India, uranium is embedded in the igneous and metamorphic rocks in Jharkhand, Rajasthan, Andhra Pradesh and some parts of Himalaya. A substantial source of uranium deposits is also found in the monazite sands along the Kerala coasts.
Thorium is principally obtained from monazite. The beach sands of Kerala in Palghat and Quilon district contain the world’s richest monazite deposits. It also occurs on the sands of Visakhapatnam in Andhra Pradesh.
