Abstract
This study was performed in order to determine and compare the response of several different dosimetry media in various exposure categofies. In order to justify the use of an electronic dosimeter as an adequate badge of record, an electronic dosimeter must be on par with accepted external dosimetry standards. Additionally, recent studies determined that a multiple diode electronic dosimeter may be considered the best candidate for use as a badge of record. The response of two commercially available electronic dosimeters, a single diode and a three-diode configuration, and a four-filter TLD packet are compared in this investigation. The exposure categofies include dose output linearity, dose rate linearity, angular dependence, incident photon energy dependence, and noble gas fission product exposure testing. These exposure categories are meant to simulate most conditions encountered in an operational setting. The responses of each dosimeter are compared to applicable industry standards. The major results include electronic dosimeter underresponse at 112 rem min-', single-diode electronic dosimeter underresponse for 100-200 keV photons, excellent deep dose agreement between the three dosimeters in the noble gas environment, and shallow dose disagreement between two TLD algorithm and the three-diode electronic dosimeter.
