Alpha-emitting substances, such as radon gas, can be a serious health hazard only if [tex]\boxed{{\text{A}}{\text{. they are inhaled or eaten}}}[/tex].
Further Explanation:
Radioactivity is the emission of elementary particles by unstable nuclei on disintegration. It is also known as radioactive decay or radioactive disintegration. Such materials or substances are called radioactive substances. A large amount of energy is released when radiations are emitted by these substances.
Radon is a natural gas that is radioactive in nature. It comes from the radioactive disintegration of uranium. It is found in igneous rocks, soil or sometimes in water. When radon gas is breathed in, its radioactive particles enter the lungs and radiations are emitted out from these. The radiation exposure of these radiations can damage the cells and leads to lung cancer. The severity of lung cancer depends on the extent of radon inhalation. It is another major cause of lung cancer after cigarette smoking.
