He turned to aluminium, which emitted an alpha particle and produced sodium, which then decayed into magnesium by beta particle emission.
In other cases the product nucleus is unstable and decays, typically emitting protons, electrons (beta particle) or alpha particles.
He tried lead, without success, and then fluorine in the form of calcium fluoride, which emitted an alpha particle and produced nitrogen, decaying into oxygen by beta particle emission.
There are several different kinds of these particles, but the majority are alpha particles, beta particles, neutrons, and protons.
Count rates are normally associated with the measurements of particles, such as alpha particles and beta particles.
Negatively charged beta particles or positively charged alpha particles, positrons or fission fragments may be utilized.
Although beta particles scatter much more than alpha particles, a range can still be defined; it frequently amounts to several hundred centimeters of air.
These systems use radioisotopes that produce low energy beta particles or sometimes alpha particles of varying energies.
