This site has been established for applicants to the accreditation program for testing radiation detection instruments. On this site you will find important program information and links to documents required for successful participation in the program.
This accreditation program is designed to satisfy the requirements of contractors, state and local governments, and federal agencies specifying accreditation for laboratories that conduct testing of radiation detection instruments used in homeland security applications. Accreditation is available to any organization that conducts testing of radiation detection instruments in accordance with the established requirements of accreditation.
For information on the requirements of accreditation see NIST Handbook 150 which contains the general requirements that are the basis for accreditation of any laboratory regardless of the discipline or area for which a lab seeks accreditation. In addition, the radiation instrument testing laboratory must meet the program-specific requirements in NIST Handbook 150-23 "Homeland Security Applications: Radiation Detection Instruments" and the relevant standard test methods for which the laboratory seeks accreditation. The NIST Handbook 150 Checklist and the NIST Handbook 150-23 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.
Proficiency Testing Requirements
At the present time, there is no established program for proficiency testing of laboratories accredited for Radiation Detection Instrument testing.
