Radiation that's always present
The amount of time for the amount of radioactive material in a source to decrease by a factor of 2
How far into a given material radiation can travel without being absorbed
Highly ionising, but easily stopped by paper, skin or even air
Low mass radiation, stopped by aluminium foil
Doesn't interact often, stopped by thick lead or concrete
Radiation that's stopped by several meters of water; sometimes considered the most dangerous type of radiation
Inverse-square law for gamma radiation
The number of decays per second of a source
Important experiment which showed the existence of the nucleus
