As discussed in Chapter 1, the radioactivity of heavy atoms, embodied in the three processes of α-, β- and γ-decay, were early indicators of nuclear activity. With the production of many species of nuclei in their ground or excited states through nuclear reactions such decays have been ...
Another type of beta particle is the positron, which occurs as a result of the decay of neutrons in the nucleus. These particles have the same mass as electrons, but have the opposite charge (hence their name).Gamma Rays Gamma rays, or γ-rays, represent the most dangerous result of radi...

lives for beta decay range upward from one-hundredth of a second and, for alpha decay, upward from about one one-millionth of a second. Half-lives for gamma decay may be too short to measure (around 10-14second), though a wide range of half-lives for gamma emission has been reported....

Definition:Alpha decay (also written as α-decay) is one of the three kinds of radioactive disintegration (other being beta and gamma decay) in which an unstable atomic nucleus dissipates excess energy by spontaneously ejecting an alpha particle. ...
