Application of the Power-Moderate Weighted Mean (PMM) Concept in the Calculation of Reference Values of Interlaboratory Comparisons

摘要

Recently, the Consultative Committee for Ionizing Radiations Section II, Measurement of Radionuclides, of the International Committee of Weights and Measures [CIPM-CCRI(II)], decided to apply the new concept of power-moderate weighted mean (PMM) in calculation of the Key Comparison Reference Values (KCRV), standard uncertainties and degrees of equivalence, Document CCRI(II)/13– 37. The paper will exemplify the calculations of 226 Ra activity concentration of a slag sample, using the PMM mode, for which we had recommended before the use of the weighted mean. This value will also be compared with a recently published one.
