Experimental determination of k0 nuclear data for the cesium radionuclides

Research output: Contribution to journalArticle

The current (official) k0 nuclear data for the cesium radionuclides was determined circa 1987 and was partially adopted from older literature. In this work we aimed at the redetermination of experimental k0, Q0 and Er factors with metrological care. The results are in good agreement with more recent results from other authors. Our Q0 and Er values were 2–15 and 25 % different, respectively. The k0 factors were determined according to the cadmium subtraction technique, resulting in values 3–7 % different than the official ones. Our precision and accuracy is discussed.
