For evaluating the degree of quenching in a liquid scintillation sample, the pulse height corresponding to the centroid of part at least of the net count rate - pulse height spectrum due to a radioisotope in the sample or to an external standard is determined and compared with a calibration curve. Provision is made for subtraction of the contribution of the background noise. Determination of the counting efficiency is made by interpolation on a calibration curve. |
