S. Pomme et al., Determination of burnup effects in Au-197(n,gamma)Au-198 prior to reactor neutron field characterisation, J RAD NUCL, 245(1), 2000, pp. 223-227
A simple and accurate method is presented to evaluate the burnup effects in
volved in the neutron activation of Au-197 prior to any neutron flux charac
terisation, based on the spectrometry of the Au-198 and Au-199 decay gammas
. The obtained burnup factor can be used as input for reactor neutron field
characterisation techniques using Au-197(n,gamma)Au-198 as a monitor. This
way an iterative procedure is avoided.
