MEMORANDUM To: Ryan Knox From: Derek Hagemeyer Date: 4/14/2022

Subject:

Data Verification ORAU is responsible for maintaining the NRCs Radiation Exposure Information and Reporting System (REIRS). We collect and analyze the exposure data for all NRC licensees and produce the NRC annual report on radiation exposure, NUREG-0713. As part of the data collection process, we would appreciate your assistance in verifying the data that your organization has submitted to the REIRS database. This is an informal, voluntary request from ORAU as a records management function to verify that we have received the correct exposure data for your facility.

Attached you will find a summary of the data received from your facility. The summary is presented as a distribution of the doses received at your facility for the 2021 monitoring year. The number of individuals receiving dose in each dose range is shown, as well as the collective TEDE for each dose range. The file name is assigned by ORAU upon receipt and does not require verification. Doses and dose ranges are in units of rem.

It is important to note that the distribution is based on the dose received by each individual included in your submittal. If multiple dose records were reported for an individual, the doses were summed for that individual and the individual was included in the appropriate dose range. Likewise, the total number monitored refers to the number of unique individuals included in the submittal, not the number of dose records in the submittal.

If the attached summary is not correct, please let us know within 2 weeks of the date of this report so that we may resolve the problem. Please contact REIRS support at 865.576.5092 or REIRS_support@orau.org to report any problems or questions. If you choose not to participate in this voluntary request, or if we do not receive a reply, the data will be assumed to be correct and will be processed into the REIRS database.
