Reporting Radiation Exposure Information
to the NRC
Annual reports of occupational radiation exposure are required to be reported to NRC under 10 CFR 20.2206 on or before April 30th of each year.
As of March, 2002, licensees now have the option of submitting electronic data files containing annual exposure records to the NRC via this web site, using secure Internet communication protocols.

Submit via web page
The REIRS web site can now receive electronic data files using Secure Socket Layers (SSL) within your web browser to protect sensitive data in transit via the Internet using 128-bit encryption. The data files are protected during transfer from the user PC to the web server, and during storage and processing of the records. For more information on data security, contact Technical Support.
- Review the Data Submittal
Review the annual records of occupational exposure as you have in previous years. As an aid, you can use the REIRView software which will examine the file for format and content and provide a summary of the data, as well as a detailed list of errors or warnings encountered in the data file.
- Send Cover Letter to NRC
For your official records, please send an official transmittal letter to the NRC as directed in Regulatory Guide 8.7. Include in this letter that the data file was submitted via the REIRS web page, the date submitted, and any additional information needed to process the data file.
- Submit Data
Submit the data file using the web link provided below. Print and save the submittal confirmation for your records.
- Verify distribution
Upon receipt of the data file, a summary report will be generated that will identify any errors or warnings encounted in the data file, as well as the dose totals and distribution of dose to the individuals. You will receive this file via e-mail or fax, as you direct. Review the file and reply as specified in the report.

If you have any questions or comments, please contact Technical Support.
