they are:
- Alpha particles
- Beta particles
- Gamma rays
Alpha particles is a particle which consists of 2 proton and 2 neutron.
The alpha particles can easy to block.
eg: Helium nucleus
Beta particles is a ray or radiation that emits electron and positron during the process of beta decay.
Gamma rays is a radiation which is the penetration of electromagnetic radiations during radioactive decay. These radiations were very difficult to block.
