This report describes results of the second year of a program that will enable the Nuclear Regulatory Commission to improve, demonstrate, and document traceability of its measurements to the national physical measurement standards for ionizing radiation. The principal actions being taken are: (1) characterization of the response of thermoluminescence dosimetry systems used for routine surveillance of nuclear facilities; (2) type testing and characterization of portable survey instruments; and (3) implementation of routine quality assurance services that will demonstrate that regulatory measurements are sufficiently consistent (in agreement) with national measurement standards. During the year, some tests of the TLD system were performed as specified in American National Standard N545-1975, specifically self-irradiation, directional dependence, humidity dependence at extreme temperatures, and salt spray. Measurement assurance tests were conducted for the NRC Region-1 laboratory. The response of six portable survey instruments to beta radiation from xenon-133 was determined using a specially-built chamber for exposure to gaseous sources. The basic principles under which the long-range interactive MQA program will operate have been developed and documented, along with procedures for obtaining essential information from participating laboratories.
