Understanding What Radiation Is
Radiation is energy that travels through space in the form of waves or particles. Some types are harmless, while others can damage cells depending on their strength.
Types of Radiation
There are two main types: non-ionizing radiation, which includes light, radio waves, and microwaves; and ionizing radiation, which includes X-rays and gamma rays.
How Radiation Works
Radiation spreads energy from one place to another. For example, sunlight warms the Earth, and medical X-rays pass through the body to create images.
Everyday Sources of Radiation
Radiation comes from many natural and man-made sources, such as the sun, electronics, medical scans, and even certain rocks and building materials.
