[edit] Beta Radiation

In nuclear physics, beta decay is a type of radioactive decay in which a beta particle (an electron or a positron) is emitted. In the case of electron emission, it is referred to as "beta minus" (β−), while in the case of a positron emission as "beta plus" (β+).[1]
Beta Decay is the most common type of radioactive decay

A B- particle is emitted from the nucleus during the decay of a neutron into a proton, and a B+ in the decay of a proton into a neutron.
In the alpha and beta decay of radioactive nucleus, "transmutation" of elements occur-an atom of one element becomes an atom of another element, as the number of protons in its nucleus changes.
Beta radiation is made up of high energy electrons
