Abstract >A simple, accurate procedure is described for correcting counting errors due to quenching in small-volume liquid scintillation detection methods. The method is only valid for higher activities and does not appear to be appropriate for routine counting operations. The method is based on the fact that the ratio of the counting rates between the two windows is a measure of the degree of quenching. Representative C/sup 14/ quenching factors and calculated errors for various levels of activity are tabulated. A tabulation of error determinations for various quenching materials and comparison to internal standard error determinations is also given. (N'W.R.)
