[en] The response of albedo personnel neutron dosimeters to neutron radiation is significantly dependent on energy (Brackenbush et al. 1980). Typically dosimeters are calibrated to the neutron spectra expected in the work environment to improve the accuracy of recorded personnel dose. Often, the field environment providing the most significant personnel neutron dose is selected as the basis for calculating personnel neutron dose. At Hanford, the open-quotes fluorinatorclose quotes hood at the Hanford Plutonium Finishing Plant (PFP) was selected as the work environment providing the greatest potential for neutron dose to Hanford personnel. This work environment has been characterized on numerous occasions to ensure that personnel doses determined with the Hanford albedo dosimeter, using the Hanford site-specific calibration, correctly determines the actual neutron dose for this location
