Abstract

Multipurpose research reactors require monitoring of neutron flux parameters (α, f, F c or Φ th ) during every irradiation of samples when k0 standardization in neutron activation analysis is to be used, because the above parameters may change quite frequently and unpredictably. We tested two monitor sets consisting of Au+Zr and Au+Mo+Cr for determination of the neutron flux parameters in k0-NAA at the LVR-15 reactor in Řež. Based on analysis of several reference materials, we found the use of the Au+Zr monitor set superior over the Au+Mo+Cr monitor set in the specific conditions of the LVR-15 reactor.
