Explanation:

Radon -

Radon is one of the radioactive noble gas, It is highly radioactive, hence, is dangerous for health. Radon is formed by the radioactive decay of the uranium into Lead.

The half life is equal to 3.8 days.

Radon is is very dense in nature.

Since, radon is a noble gas so, it does not react with the surroundings.

In the clay, the radon gets lost immediately from the source rock through the fractures.
