There is an important distinction between NVLAP and DOELAP accreditation.
NVLAP accredits only the processing function, and accreditation can be
obtained by any organization that can successfully meet the NIST criteria.
In the NRC-regulated world, dosimetry used to demonstrate compliance with
dose limits in 10CFR20 must be processed by an accredited processor.

DOELAP accredits the dosimetry user, which includes proficiency testing and
assessment of the processor as well as the operating organization using the
dosimeters. Thus, you can go shopping for the services of a
NVLAP-accredited commercial processing company, but, as a dosimetry user,
you must obtain accreditation from DOELAP. This can be done using a
commercial processor.
