This report describes a program to improve, demonstrate, and document trace-ability of its measurements to the national physical measurement standards for ionizing radiation. The principal actions taken were: (1) characterization of the response of a thermoluminescence dosimetry system used for routine surveillance of nuclear facilities; (2) characterization of the response of six models of portable survey instruments; and (3) implementation of routine quality assurance services that will demonstrate that laboratories which calibrate survey instruments for the NRC are sufficiently consistent (in agreement) with national measurement standards. Tests of the TLD system were performed as specified in American National Standard N545-1975, plus several additional tests not contained in that document. Measurement assurance tests were conducted for the NRC Region-1 laboratory. The response of the survey instruments was determined for photon energies as high as 6.5 MeV, and for beta particles of various energies, including those emitted by /sup 133/Xe gas. The basic principles under which the long-range interactive MQA program will operate were developed and documented, and the feasibility of the program was demosntrated. 14 references, 46 figures, 49 tables.
