3 common types of radiation are
|
alpha, beta, and gamma.
|
|
|
Properties of alpha radiation are

Properties of beta radiation are
|
High speed electrons (- charge) emitted from unstable nuclei
|
|
|
Properties of gamma radiation are
|
High energy electromagnetic radiation of very short wavelength that usually accompanies other radioactive emission.
