Abstract: The use of U and Th thin films, attached to detectors of fission tracks, allows determining the neutron fluence in nuclear reactors. In principle, the parameters involved in neutron fluence determinations through U and Th thin films that might be influenced by effects related with fission fragments and α particle energy absorption are: (i) the detection efficiency of nuclear emulsions for α particles, (ii) the detection efficiency of muscovite mica for fission fragments from thin films, ε{lunate}F and (iii) the detection efficiency of nuclear emulsions for fission fragments, used to estimate ε{lunate}F. Fission fragments are more ionizing than α particles and are more influenced by energy absorption. We show that fission fragment energy absorption effects are negligible in case of U and Th thin films employed in neutron fluence determinations for fission-track (FT) dating. © 2008.
