The responses of several types of high-energy personnel neutron dosimeters were studied in the operational radiation fields at the Alternating Gradient Synchrotron. Included in the study are intercomparisons of polycarbonate, type A neutron track emulsion, allyl diglycol carbonate, electrochemical etch allyl diglycol carbonate, TLD-600, and TLD-700. Some of the passive measurements were compared with active tissue-equivalent instruments. The trend for many but not all of the measurements was for type A neutron track emulsion to report the highest neutron dose equivalent. The polycarbonate returned intermediate values while allyl diglycol carbonate usually reported the smallest values. Quality assurance data from calibration sources through 1990 are also provided.
