Third intercomparison of DOE High-Energy Neutron Personnel Dosimeters
- Department of Energy, Washington, DC (United States)
An intercomparison of the dose equivalent response of personal dosimeters in use at U.S. Department of Energy (DOE) accelerator facilities was performed at the European Laboratory for Particle Physics (CERN). This is the third such intercomparison sponsored by the DOE. The two previous intercomparisons were performed in a U.S. laboratory using a source of high-energy neutrons. This intercomparison was performed at two positions relative to the main beam line at CERN. The neutron-energy spectra present at these two locations were measured by CERN personnel using Bonner sphere spectrometer systems. In addition, the dose equivalents at these two positions were also measured by CERN personnel using a tissue equivalent proportional counter system. The DOE dosimeters were mailed to CERN and returned after irradiation for readout. The results of this intercomparison are relatively consistent with the two previous intercomparisons performed in the U.S. The relative dose equivalent responses of neutron dosimeter types, such as albedo, nuclear emulsion and track-etch plastics, were found to have variations relative to the mean value responses of up to a factor of three.
