Thorium is a radioactive chemical element that can be found in soil and rocks. In its purest form, it appears as a silver metal, but when heated in the air, it becomes like a white light, like lightning.

Thorium is currently used in things such as light bulbs and camera lenses. It can create a high-quality refractive glass, and its high melting point can allow ceramics to resist high temperatures.

But light bulbs and ceramics aren't what have the energy industry watching closely.

It is present in the soil also. In India Kerala, Monozite belt is known for it.

Monozite soil has the rich quantity of thorium.

What is the properties of the thorium?

Thorium is also used as nuclear fuel in power generation.

It's option D.

Radon is the radioactive pollutant of recent public concern due to its occurrence in building materials, because it is a naturally occurring radioactive gas that can accumulate in homes and buildings, leading to increased lung cancer risk. It results from the decay of uranium and radium found in soil, rocks, and some building materials, and its colorless, odorless, and tasteless nature makes it difficult to detect without specialized equipment.
