http://nothingnerdy.wikispaces.com/RADIOACTIVE+DECAY
Nuclear reactions that involve the decay or formation of a neutron also produce
particles of very little mass and no charge known as neutrinos.
An example equation is shown below:
http://nothingnerdy.wikispaces.com/RADIOACTIVE+DECAY
After decay, a nucleus may still have excess energy that is lost by
emitting electromagnetic radiation of very high energy
known as gamma radiation.
Gamma radiation is very high energy electromagnetic radiation (a high energy photon).
