Abstract
System for measuring absolute activity of radionuclides using electronic permutation of the channels of the measuring system.System for measuring absolute activity of radionuclides using a method of matches in a liquid scintillator with a head of k photomultipliers with an equal average efficiency in each channel using electronic permutation of the channels.The purpose of the invention is the implementation of a channel that measures the ionising radiations with k photomultipliers in order to record the light flashes produced in the middle of the liquid scintillator. The head can be made so that it allows obtaining averaged values of the signal parameters that appear in the measuring channels of a matching system.
