Bulk hydrogen analysis using epithermal neutrons

Journal of Radioanalytical and Nuclear Chemistry Aims and scope Submit manuscript

Summary

A new method based on the epithermal neutron activation has been developed for bulk hydrogen analysis. The sensitivity of the activation method for typical sample dimensions is higher by a factor of ~100 than the neutron reflection technique. Analytical expressions are given for the description of the measured flux density of thermalized neutrons as a function of hydrogen content of different samples. Advantages and limitations of thermal and epithermal neutrons in bulk hydrogen analysis using the foil activation method are also discussed.
