... Skin can stop alpha radiation Beta radiation – usually only penetrates 1-2cm beneath the skin Alpha, beta and gamma are “ionizing radiation” – they have enough energy to break bonds in molecules which ionizes them, which makes them unstable, and very reactive inside the organism Find out more at Ion ...

They can easily penetrate barriers, such as skin and clothing that can stop alpha and beta particles. Gamma rays have so much penetrating power that several inch ...

Background radiation
Background radiation is the ubiquitous ionizing radiation that people on the planet Earth are exposed to, including natural and artificial sources.Both natural and artificial background radiation varies depending on location and altitude.
