Penetration of Gamma rays. Gamma rays are the most penetrating of the radiations. Gamma rays are highly energetic waves and are poor at ionising other atoms or molecules. It cannot be said that a particular thickness of a material can absorb all gamma radiation. Many centimetres of lead or many meters of concrete are required to absorb high levels of gamma rays.

Description:
Gamma radiation is highly penetrating and interacts with matter through ionisation via three processes; photoelectric effect, Compton scattering or pair production. Due to their high penetration power, the impact of gamma radiation can occur throughout a body, they are however less ionising than alpha particles. Gamma radiation is considered an external hazard with regards to radiation protection.

Gamma rays are the most hazardous type of radiation from sources outside the body because they can travel much greater distances through air and all types of material. Gamma rays can travel up to a mile ( km) in open air and may present a significant hazard even at fairly large distances.
