The report records must be kept on file permanently. A photocopy of these records should be made available to employees upon request.

While dosimetry service and records are very important your selection of a dosimetry provider should be based on the following:
The dosimetry provider should be, or act as an agent for, a National Voluntary Laboratory Accreditation Program (NVLAP) approved lab. You may be surprised to find that your current dosimetry provider is only acting as a middleman for one of the larger NVLAP Labs. That’s okay providing the price is right. There is essentially no difference in analysis quality if the lab is NVLAP approved. Your badges or TLD’s and reports should come in on a timely basis.
Go with the best pricing – these charges can add up quickly. Watch out for set-up charges and long term agreements. You can save a lot of money by choosing the right company. You should be using a quarterly service – monthly service is generally not necessary and is usually more expensive. Check with your regulatory agency for minimum requirements.
There are only a handful of NVLAP providers. The large providers are Global Dosimetry and Landauer. Many manufacturers and gauge repair companies offer dosimetry through these two companies – they are just acting as a middleman, although some will actually save you more money than going directly to the large provider, as well as offering more direct interaction. You should always shop around for the best service and pricing.
