Reference Dosimetry for the 1992 NATO Battlefield Dosimetry Intercomparison atthe Army Pulse Radiation Facility

摘要

A NATO Dosimetry Study was performed from 23 March to 3 April 1992 at the ArmyPulse Radiation Facility (APRF), Aberdeen Proving Grounds, Aberdeen, Maryland. This study was designed to determine the accuracy of battlefield dosimeters in a simulated tactical environment, and to compare the different NATO dosimeters in simple, well-defined radiation fields. Dosimeters were irradiated in four radiation fields; in free air (FIR) and on the surface of Polyethylene phantoms by the APRF reactor with the core bare and with the core shielded by a convertor shield. Measurements to provide reference dosimetry for the NATO Dosimetry Study were made the week before and the week following the above dates and also during the second week of the battlefield dosimeter comparisons. Reference dosimetry for the NATO Dosimetry Study reactor irradiations was performed by three dosimetry groups.
