Alpha-emitting substances, such as radon gas, can be a serious health hazard only if .

Further Explanation:

When an unstable nucleus tends to stabilize itself by the emission of radiations such as alpha particles, beta particles and gamma rays, the process is called radioactivity. Such substances are known as radioactive substances. This process is also called radioactive disintegration or decay. Uranium, carbon-14, iridium-192 and cobalt-60 are some examples of radioactive substances.

Radon is a radioactive natural gas that is produced from the radioactive disintegration of uranium. It is the second major cause of lung cancer after cigarette smoking. The radioactive particles present in radon gas are released by it when radon is inhaled or ingested in the body. When the skin comes in contact with these radiations, cells and tissues are damaged. It leads to lung cancer. The risk of lung cancer depends on the extent of radon inhalation.
