What is Radiation?

Radiation

Radiation describes the process of which energetic particles or waves travel through a material or space.

Ionizing radiation

Ionizing radiation is radiation with sufficiently high energy that can ionize atoms. Most often, this occurs when an electron is knocked out from an electron shell, which leavs the atom with a net positive charge.

There are five types of ionizing radiation:

1. Alpha
   
2. Beta(+/-)


3. Gamma


4. X-Ray


5. Neutron

Non-Ionizing radiation

Non-ionizing form of radiation on living tissue have only recently been studied. instead of producing charged ions when passing through matter, the electromagnetic radiation has sufficient energy to charge only rotational, vibrational or electronic configurations of molecules and atom.

There are five main Non-Ionizing Radiation forms:

1. Visible light
2. Infrared
3. Microwave
4. Radio Waves
5. Thermal Radiation
