Abstract

This report contains details of the experimental procedures used by NPL to measure the neutron emission rate of the 241Am-Be source used in the CCRI international comparison exercise CCRI(III)-K9.AmBe. Measurements were made using the NPL manganese bath facility in 1999 and again in 2004. A description is also given of the analysis technique and the various corrections applied. The final values for the neutron emission rate into 4p sr of the source corrected to 1 January 2000 are given together with a detailed breakdown of the uncertainties.
