What is gamma radiation
Gamma radiation is a form of electromagnetic radiation not a type of particle
What happens when an atoms nucleus decays and emits gamma radiation
It releases energy in the form of electromagnetic radiation
Gibe an example of an alpha particle use
Present in smoke alarms- if there is smoke present , it interacts with the ions produced in the alpha particles and ionisation is reduced
Give an example of what beta radiation is used in
Thickness control mill - if nit enough radioactivity is detected then the rollers compress to make materiak thinner
Give an example of what gamma rays can be used in
They can be used to detect cracks after a pipe has been weeded
What is an alpha particle made from
2 neutrons 2 protons
What are beta particles made from
Free electrons made in the nucleus
What are positrons made from
Opposite charge of an electron
What are gamma rays made from
A ray of pure energy
