This accreditation program is designed to satisfy the requirements for processing personnel dosimeters (whole body badges and extremity badges) to determine the dose of record for the occupational worker. Accreditation is available to any dosimetry processor. It is required by regulation that licensees of the U.S. Nuclear Regulatory Commission have personnel dosimeters processed by a NVLAP-accredited processor.
For information on the requirements of accreditation, see NIST Handbook 150, which contains the requirements that are the basis for accreditation of any laboratory regardless of the discipline or area for which a lab seeks accreditation. In addition, ionizing radiation dosimetry processors must meet the program-specific requirements in NIST Handbook 150-4, NVLAP Ionizing Radiation Dosimetry.
The NIST Handbook 150 Checklist and the NIST Handbook 150-4 checklist are used by the assessor when performing the on-site assessment. In addition, NVLAP Lab Bulletins may be issued to expand the requirements or to provide clarity on existing requirements.
The dosimetry processor must satisfactorily participate in proficiency testing for the dosimeter types and radiation categories for which the laboratory seeks accreditation. The proficiency testing is provided by Pacific Northwest National Laboratories (PNNL), (http://cra.pnnl.gov), and is performed against ANSI/HPS N13.11-2009, Personnel Dosimetry Performance – Criteria for Testing for whole body dosimeters and ANSI/HPS N13.32-2008, Performance Testing of Extremity Dosimeters for extremity dosimeters.
The proficiency testing contact at PNNL is Jamie Eder, phone: 509-375-7361; email: Jamie.Eder [at] pnnl.gov (Jamie[dot]Eder[at]pnnl[dot]gov).
