Types of Nuclear Radiation
There are four types of nuclear radiation:
Gamma Photons: packets of high energy electromagnetic radiation... pure energy, no matter! High frequency and high energy. The only sort of electromagnetic radiation that comes from the nucleus is the gamma ray.
These are only given
out by the nuclei of nuclides that have too many protons to be stable.
These have only been discovered since we have been able to artificially
'make' isotopes that did not occur naturally on Earth during the last
century. Some of these decayed to produce these antimatter particles.
If a positron meets up with an electron they annihilate
each other. and gamma rays are produced (but that is only tackled at
