Liquid scintillation counting techniques combined with the CIEMAT/NIST method have been applied to measure the specific activity of natural potassium salts. Samples have been prepared with three different scintillators. The individual atomic composition as well as the density of the cocktails have been taken into account for the efficiency calculation. With the specific activity the half-life is calculated to be T-1/2 = 1.248(3) x 10(9) a. The result is in reasonable agreement with other measurement results provided the same isotopic concentration of K-40 is used. (C) 2003 Elsevier Ltd. All rights reserved.
