The Sixteenth Nuclear Accident Dosimetry Intercomparison Study was conducted August 13-17, 1979, at the Oak Ridge National Laboratory (ORNL). Nuclear criticality accidents with three different neutron and gamma energy spectra were simulated using the Health Physics Research Reactor (HPRR) operated in the pulse mode with different shielding configurations. Participants from 13 organizations exposed dosimeters set up as area monitors and mounted on phantoms for personnel monitoring. The composite of all reported dose results failed to meet nuclear criticality accident dosimetry guidelines which suggest accuracies of +-25% for neutron dose and +-20% for gamma dose. This indicates that continued development and evaluation of criticality accident dosimetry systems and analysis techniques are necessary to improve measurement accuracy so that existing standards can be met.
