Radiation Types

Radiation Types

Some atomic isotopes are unstable and emit radiation, they become more stable. This process is called Radioactive Decay.

Isotopes - Elements with a different number of Neutrons.

There are 3 types:

Alpha - α

Beta - β

Gamma - γ

Alpha

Electric charge: 2+

Relative atomic mass: 4

Penetration power: Goes through plastic and stops.

Ionising effect: Big/heavy so…
