Thorium is also a potential nuclear fuel of the future. Exposure to thorium is encountered in the mining and milling of monazite (thorium ore) and at various other stages in the thorium industry. In order to assess the handling hazards of thorium minerals and compounds, it is important to study this element in the normal environment.
India: In the coastal areas of Kerala and Tamil Nadu in India a narrow coastal strip is rich in monazite, ilmenite, rutile and zircon. In one part of the strip, populated by about 1,000,000 persons, the thorium concentration averages between 8% and 10.5% in patches; the average dose rate for the regions is about 1.3 μGy h −1, with maxima up ...

Uranium and Thorium are the main atomic minerals to which may be added i.e., beryllium, lithium, and zirconium. Thorium is derived from monazite which contains 10 percent thoria and 0.3 percent urania. The other mineral carrying thorium is thorianite. The nuclear power plants in India use nuclear fuel processed in three stages.

The radiological safety provisions in the thorium mining and milling as well as the industrial and fire safety aspects in thorium milling are enforced by the Atomic Energy Regulatory Board (AERB), which is the national regulatory body of India for nuclear and radiation safety.
Pillai says that depending on the monazite concentration in the raw sand, radiation exposures of the order of 0.13-1.00 man-milli seivert (msv) per tonne are involved in the mining and separation of monazite. Monazite contains 0.2 -0.4 per cent of uranium and 4.5-9.5 per cent of thorium which occurs as oxides depending on the region of occurrence.
General, Domestic India to develop 13 new uranium mine projects, increasing production by factor of up to four The Uranium Corporation of India Limited (UCIL) will be taking up 13 uranium mining projects across the country with an outlay of Rs 105.7 billion [US$ 1.52 billion], aiming to increase its production by up to four times in the near future.
