Two radioactive sources are stored in a physics laboratory. One source emits only beta (β\betaβ) particles and the other source emits only gamma (γ\gammaγ) rays.
Suggest how these two sources can be identified using laboratory equipment.
State two ways in which beta particles are different from alpha (α\alphaα) particles.
