What is Radiation? Radiation is the process by which energy is emitted in the form of waves or particles from a source. It encompasses a broad spectrum of electromagnetic waves and particles, each characterized by its unique energy level and frequency. Radiation is present in various aspects of daily life, from natural sources like the sun to man–made technologies such as X–rays and nuclear reactors. Understanding the types of radiation and their potential impact is crucial for ensuring safe and controlled usage.
Types of Radiation
1. Ionizing Radiation
- Sources: X-rays, gamma rays, alpha and beta particles.
- Effect: Causes ionization in cells, influencing genetic material.
2. Non-Ionizing Radiation
- Sources: Microwaves, radio waves, infrared, and ultraviolet rays.
- Effect: Typically induces thermal effects rather than ionization.
