Abstract
To produce a quench calibration function for a liquid scintillation counter having stored a basic correlation between a quantity to be quench calibrated and a quench index, the value of the quantity to be quench calibrated and the value of the quench index for at least one reference sample is measured by measuring means from said basic correlation, the value of the quantity to be quench calibrated for the measured value of the quench index for each reference sample is evaluated by evaluating means. Then the difference or ratio between the measured and the calculated values of the quantity to be quench calibrated for each reference sample is calculated by calculating means, whereupon said calculated difference or ratio as a function of quench index is approximated by approximating means, and said basic correlation and said function of quench of quench index are combined into the quench calibration function by combining means.
