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 ...
Alpha, beta and gamma radiation are the original and still-standing names for the three major types of radioactive decay of atomic nuclei. These are the first three letters in the Greek alphabet and represent increasing levels of biological danger upon e
Fig. 3. Positron decay. An example of this decay occurs in sodium-22 nucleus that decays into neon-22 nucleus with the emission of beta-plus particle. 1.2.3 Gamma decay In gamma decay, the parent isotope emits a gamma photon that has no charge (Fig. 4). The parent isotope is in exc...

(ZnS:Ag) applied to one side. The primary use of EJ-444 is the detection of alpha and beta particles in health physics instrumentation. A non-coated plastic scintillator may also be used for this purpose, but the amplitudes of the alpha and beta pulses are sufficiently similar to make it...
