Physics - Radiation section 7
The basics of Alpha, Gamma, beta
Beta
Speed: Fast
Mass: Small
It is Electron
Penetrating power: Medium (Aluminium stops it)
Ionisation power: Medium (Interacts a bit)
Gamma
Speed: Speed of light
Mass: None
It is a Electromagnetic wave
Penetrating Power: High (thick lead or concrete to stop)
Ionisation power: Low (Hardly interacts)
Alpha
Speed: Slow
Mass: Big
It is Helium nucleus (2 protons and 2 neutrons) this is the biggest one
Penetarting power: Low (Paper stops it)
Ionisation power: High (interacts with everything)
