Radiation

Radiation as used in Physics , is Energy in the form of Waves or moving Subatomic Particles . Radiation can be '' Ionizing '' or '' Non-ionizing Radiation '', depending on its effect on atomic Matter . The most common use of the word "radiation" refers to ionizing radiation. Ionizing radiation has enough energy to ionize atoms or molecules while non-ionizing radiation does not. '' Radioactive Material '' is a physical material that emits ionizing radiation.

TYPES OF RADIATION
