Abstract
The MGP DMC 2000S and the NRC UDR-13A electronic dosimeters have been tested by DREO for acquisition project G2199 "Nuclear Detection, Identification and Dosimetry". These tests were carried out with the wide array of radioactive sources available at DREO, with the X-ray facility available at the National Research Council, and with one of the environmental chambers available at the Quality Engineering Test Establishment (QETE). Both meters are capable devices, suitable for the electronic dosimetry role. However, DND must be aware of the following shortcomings: (a) Their energy response is not constant. This is not a critical problem since personal dosimetry will be carried out with Thermoluminescent Dosimeters (TLDs). (b) When placed on certain parts of the reader, the MGP dosimeters will register high levels of radiation in the absence of such a field. This shortcoming must be discussed with MGP. (c) The MGP dosimeter, due to the small size of the detector, is not suitable for an expanded role including tasks suited to a radiation survey meter. (d) Neither meter is operable following long-term (2-hour) exposure to temperatures below -20C. However a dosimeter worn under a coat should be operable without problems.
