3Particle beam weapon — A particle beam weapon uses an ultra high energy beam of atoms or electrons (i.e., a particle beam) to damage a material target by hitting it, and thus disrupting its atomic and molecular structure. A particle beam weapon is a type of directed… …
4Alpha particle — Alpha particles (named after and denoted by the first letter in the Greek alphabet, α) consist of two protons and two neutrons bound together into a particle identical to a helium nucleus; hence, it can be written as He2+ or 42He2+. They are a… …
5subatomic particle — or elementary particle Any of various self contained units of matter or energy. Discovery of the electron in 1897 and of the atomic nucleus in 1911 established that the atom is actually a composite of a cloud of electrons surrounding a tiny but… …
6Double beta decay — is a radioactive decay process where a nucleus releases two beta rays as a single process. In double beta decay, two neutrons in the nucleus are converted to protons, and two electrons and two electron antineutrinos are emitted. In the process of …
7Common beta emitters — Contents 1 Fission products 1.1 Strontium 2 Neutron activation products 2.1 Tritium 2.2 Carbon …
8Alpha-particle spectroscopy — One method for testing for (and measuring) many alpha emitters is to use alpha particle spectroscopy. For methods for gamma rays and beta particles, please see gamma spectroscopy and liquid scintillation counting respectively. Experimental… …
9liquid scintillation counter — noun A piece of laboratory equipment used to analyse solutions of a beta particle emitter by measuring the scintillations from a scintillation cocktail …
10scintillation cocktail — noun A solution of a beta particle emitter to be analysed in an organic solvent along with a fluor which emits a scintillation of light, which can then be detected by a liquid scintillation counter …
