Personnel neutron dosimetry using particle tracks in solids: a comparison

Comparison of two nuclear track methods of dosimetry for fast neutrons shows similar uncertainties for manual counting of etched tracks as for electrochemical read-out by a commercial service. The standard deviation is approximately 30% under rigorous specification of conditions, i.e. monoenergetic neutrons and minimum neutron scattering. Because this or greater uncertainty is common to most methods, such doses should not be quoted to higher precision.
