Radiation

Radiation

1. Alpha

   • Helium Neculi
   • Consists of 2 Protons and 2 Neutrons
     • Thus has an Atomic Wight of 4
   • Has a 2+ Charge
   • Stopped by paper or a few cm of Air
   • Strongly Inonising
     • Ionising simply means that it takes away or gives electrons to atoms.
   • Weakly deflected by Electromagnetic feilds
     • Has High Momentum
       • Linked to high mass

2. Gamma

   • High Energy Electromagnetic Radiation
   • Has no Electric Charge
   • No Atomic Mass
     • Wave, not a particle
   • Reduced by a few cm of Lead or meters of Concrete
     • Due to such high energies involved
     • Can't stop them totaly
   • Very weak Ionising Effect
     • Happens if it knocks off an electon
   • No deflection from Electromagnetic Fields

3. Beta

   • High Energy Electron, from the Nucleus
     • Atomic weight of 1/1860
   • Has a Charge of 1-
   • Stopped by a few mm of Aluminium
   • They are weakly Ionising
   • They are strongly deflected by Electromagnetic feilds
     • Has a very low mometum
       • Linked to low mass
