Radionuclide Analyses,mportant condition for radionuclide detection and/or spectrometry is the elimination of disturbances leading to creation of false counts. A comprehensive description of different arrangements for activity measurements of radionuclides are to be found in the specialized monographs .

Basic Terms of Radioactivity,1871–1937) found that there are at least two components of the radiation emitted by these elements. In 1899, the same physicist distinguished alpha and beta particles. The following year, Paul Villard (1860–1934) discovered and described the gamma rays emitted by radium.

Basic Terms of Radioactivity,–1923) in 1895. Radioactivity was accidentally discovered by the exposure-producing effect on a photographic plate by a mineral containing uranium — pitchblende, when wrapped in a black paper and kept in the dark. Soon after the fundamental discoveries, Pierre Curie (1859–1906) together with his wif

Radionuclides Released into the Environment,e soil, and in the water by influences from the cosmos. From the fission fragments and activation products generated by the spontaneous nuclear reactions of uranium (see Chap. 2, 1.3.2, Oklo phenomenon) it becomes obvious that, in principle, nearly all radionuclides might occur. Short half-lives and
