The laboratory accreditation program for Ionizing Radiation Dosimetry was established in 1984 in response to a request from the U.S. Nuclear Regulatory Commission (NRC). The purpose of the NVLAP Ionizing Radiation Dosimetry Program is to recognize competent dosimetry processing laboratories and to improve the quality of personnel dosimetry by providing periodic evaluations of each laboratory, including an assessment of the laboratory's management system.
