physics 10 2 radiation :)

1. alpha particals summery

• beta particles have virtually no mass and are used to detect thickness of metal as unlike alpha particles they wont dissolve right away. they penterate moderatly BPARTICLE before colliding into a material and are partially ionising
• alpha particles - symbol a used in smoke alarms are fully absorbed by a sheet papaer and when they are emitted froma nucleus alpha radiation takes place they contain 2x protons 2x neutrons
• not incorrect key fact B PARTICLE - they are super fast moving electrosna snd for every beta particle emitted a neutron particle has turend to a proton
• no incorrect answer key facts - they have 2x neutrons 2 x protons in the nuclei and its like a hellium balloon they are often used in smoke alarms as they bind to ions and stop charge flow makeing the alarm go of
