Uses of radiation in radio dating
Similarly, radiation is used to help remove toxic pollutants, such as exhaust gases from coal-fired power stations and industry.
For example, electron beam radiation can remove dangerous sulphur dioxides and nitrogen oxides from our environment.
In addition, radiation has useful applications in such areas as agriculture, archaeology (carbon dating), space exploration, law enforcement, geology (including mining), and many others.
Archaeologists also use radioactive substances to determine the ages of fossils and other objects through a process called carbon dating.
For example, in the upper levels of our atmosphere, cosmic rays strike nitrogen atoms and form a naturally radioactive isotope called carbon-14.
Carbon is found in all living things, and a small percentage of this is carbon-14.
These instruments provide doctors with color images that show the shapes and details of internal organs.
This helps physicians locate and identify tumors, size anomalies, or other physiological or functional organ problems.

The most common of these medical procedures involve the use of x-rays — a type of radiation that can pass through our skin.
