There are many sources of radiation exposure, including natural as well as manmade. For example, people are exposed to varying amounts of radiation from sunlight, rocks and soil, food, water, air, airline travel, some medical procedures, computers, and nuclear weapons test fallout.
Understanding Radiation
Radiation, which exists all around us is characterized in two forms—ionizing and non-ionizing radiation.
Ionizing and Non-Ionizing Radiation
Non-ionizing radiation has less energy than ionizing radiation. Its uses include lasers, microwaves, infrared lamps and radio waves.
The most energetic form of radiation is ionizing radiation. Ionizing radiation is used to generate electric power, treat cancer, take x-rays and disinfect medical instruments.
