what is background radiation
radiation that is around us all the time
2 of 12
what was rutherfords alpha particle scattering experiment
firing alpha particles at a thin metal foil
3 of 12
what happens to the mass number of a nucleus when it emits a beta particle
it stays the same
4 of 12
what happens to the atomic number of the nucleus when it emits a beta particle
it goes up by one
5 of 12

why is gamma radiation not deflected by electric and magnetic fields
gamma raditaion is uncharged
8 of 12
what has happened to the number of atoms undergoing nuclear decay in a sample after 3 half lives have passed
it has decreased to 1 8th of its original value
9 of 12
why is alpha radiation unsuitable for motoring the thickness of metal foil
alpha radiation would not be able to pass through the foil, irrespective of thickness
