γ-rays belong to the electromagnetic spectrum
γ-rays do not carry an electron charge
γ-rays obey the inverse cube law in air
the thickness of aluminium which stops b-particule has a negligible effect on γ-radiation
the difference between γ-rays and X-rays is that γ-rays originate from energy charges in the nuclei of atoms, while X-rays comes from energy charges associated with the electron structure of atoms
