GAMMA PARTICLES

1) After alpha/beta particle is emitted, the nucleus will be too hot & will lose energy by emitting Gamma rays (rather than infrared radiation or EM waves - which are emitted due to hot gas) 2) Emission: Since energy levels in the nucleus are much higher than those in a gas, the nucleus emits a more energetic EM wave called a gamma ray. 3) Causes no change in no. of particles in the nucleus therefore atomic and mass number remain the same
