Multiple channel activity measurement with peak-proportional automatic Compton scattering subtraction

Nuclear measuring technique possibility of continuous quantitative element determination and of separation of a continuously flowing mixture containing three characteristic elements - i.e. they can be well activated, have short half-lives and during decay they are able to emit gamma photons - is described shortly by the author with special respect to the rapid and automatic supply of data required to the control of the separation. The automatic correction of the interfering Compton scattering and background radiation is dealt with too. (author)
