[Global] [EXTERNAL] Dosimetry records

[Droppers, Amanda Jo]

At Duke, we defined annual radworker exposure file in our procedures (see below for how we defined it) which allows us to keep all of dosimetry documents for the current year for an individual. Then our document control records management requirements take over at the beginning of the new year. We have 2 sites that are held to transfer to DCRM within 90 days and the remaining sites are within 180 days - the delta between the two is driven by site commitments when Duke Carolinas and Progress merged.

We do have a process called a satellite file exception letter which does allow records to be stored for no more than an additional 90 days (for the 2 sites held to 90 days currently - putting the max time at 180 days) or an additional 180 days (for the remaining sites held to 180 days - putting the max time at 360 days). This process has to be requested for a specific reason for the extension and must be specifically approved by our DCRM manager. We used to do this for dosimetry but once we defined what an annual exposure file is in our procedures, we got out of having to do an exception letter each year. If you have any further questions on this, feel free to reach out to me!

Annual Radworker Exposure File: The compilation of documents created for each worker activated in Sentinel or provided radiation exposure monitoring over the course of current year.

Hello all!  Hope this finds you well.  For dosimetry records (which are QA records) at your plant, how long after the year has expired do you have to transfer the dosimetry records to your Document control (at Cook we call them NDM - Nuclear Document Management)?  There is nothing in our Records Management procedure that states a 2 year period, but I have been told other plants have this.  If so, how is this documented.  Looking at our procedure it states, "unless written authorization has ben obtained from the NDM supervisor or designee to retain QA records longer than 60 days, the Record Custodian transmits QA records to NDM for processing within 60 days of completion/authentication".

I look forward to your response.

Thank You!

Olga
