  • Method for compensating measuring values when measuring the radiation from a number of radioactive samples in an automatic radiation detecting instrument
    Patent number: 4348588
    Abstract: A system for the measurement of radioactivity of a number of radioactive samples by a radiation detector which will be affected by radiation from a number of other sources having predetermined locations in addition to the sample being measured consists of first measuring the values of activity measured by the detector when a standard radiation source of known activity is placed in the detector and in each of the predetermined locations to determine the effect of the other sources on the measurements of the detector, storing the values thus determined and thereafter compensating the values of radioactivity of each sample measured by the detector with the stored values to obtain the actual values of radioactivity of the samples.
