Definition

Radiation injuries are damage to the body caused by ionizing radiation. Ionizing radiation (IR) is given off by the sun, X-ray machines, and radioactive elements.

Description

The word radiation comes from a Latin term that means "ray of light." It is used in a general sense to cover all forms of energy that travel through space from one place to another as "rays." Some forms of radiation are relatively harmless, like radio waves. Some forms of radiation carry a tremendous amount of energy and cause damage when they come into contact with other materials.

These high energy forms of radiation cause damage to substances by tearing apart the atoms and molecules that make up the substances. This may cause materials to undergo harmful changes. For example, an X ray that passes through water can tear the molecules of water apart. An X ray that passes...
