Beta radiation is similar to alpha, let see the differences in beta:
-1 charge
Low mass
Stopped by foil
Middle energy
Pass through skin 1 cm.
Fast moving electron
Gamma radiation is very different from the others, let's see how it differs:
A ray
Pure energy
All energy
No mass
No charge
Passes through body and destroys cell
β
⁰-₁e / ⁰-₁β
γ
⁰₀γ
