What is Radiation?

Radiation is the emission or transmission of energy in the form of waves or particles. It can be classified into two main types: ionizing and non-ionizing radiation.

Ionizing Radiation

Ionizing radiation has enough energy to remove electrons from atoms, creating ions. This can damage cells and DNA, and can lead to cancer and other health problems. Sources of ionizing radiation include:

• X-rays and gamma rays
• Alpha particles
• Beta particles
• Neutrons

Non-Ionizing Radiation

Non-ionizing radiation does not have enough energy to remove electrons from atoms. It can still cause health problems, but these are generally less severe than the effects of ionizing radiation. Sources of non-ionizing radiation include:

• Ultraviolet (UV) radiation
• Visible light
• Infrared radiation
• Radio waves
