Characterization of a neutron–beta counting system with beta-delayed neutron emitters

Standardisation of positron-emitters in gas with the NPL primary gas counting system.

A primary standard for positron-emitters in gas has been developed. The method involves internal gas proportional counting and the use of the PENELOPE Monte Carlo code to determine corrections for counting losses. The development work was carried out using (11)C, although the method can be applied to other positron emitters. The results were compared with measurements of (11)C (in solution) car...

Comparison of gamma-ray spectrometry and delayed neutron counting for determination of uranium.

Neutron Detection and Counting Introduction

Plutonium and uranium isotopes decay by alpha particle emission. The alpha particle is absorbed by the nuclei of the low atomic number elements (Li, B, Be, O, F, C, Si, etc.) and a neutron is produced. The yield depends upon the chemical composition of the matrix and the alpha production rate for plutonium and uranium. Neutrons from (α,n) reactions are produced randomly (not time-correlated) an...
