Nature of alpha, beta, gamma radiation
- all 3 forms of radiation can be seperated using a MAGNETIC FIELD or an ELECTRIC FIELD.
- Deflection= when it turns away from how its emitted eg emmited straight then curves away..
DEFLECTION BY A MAGNETIC FIELD
- it is easily deflected, in the same way as electrons.
- the radiation consists of negatively charged particles (-) because a 'b' particle IS a fast moving ELECTRON.
- It is emitted by an unstable nucleus that has too many neutrons
- deflected in the opposite direction of 'b' radiation- because alpha particles consist of positively charged particles (+) and 'b'is negative (-)
- They are harder to deflect than 'b' radiation -->
- because an 'a' particle has a much greater mass than than a 'b' particle has- an alpha particle has 2 protons and 2 neutrons stuck together (same as helium nucleus)
- not deflected by a magnetic OR electric field- because gamma radiation is electromagnetic- so is uncharged- that is how we kow its NOT made up…
