NRC External Exposure to Ionizing Radiation (Form 5) Updates Released

​​Anyone who is officially monitored for external exposure to ionizing radiation during the year receives an annual summary report (NRC Form 5) informing them of how much dose was measured and recorded on their official record. Our dosimetry contractor assembles these reports in late February and transfers them to the Division of Radiation Safety (DRS) for inclusion on our database and distribution to staff who were monitored. DRS will alert relevant staff via email that the Form 5 is available and provide a personalized link to access it electronically. 

As we approach February, please be sure to turn in all 2022 dosimetry you may have in your possession so that it can be processed by our contractor in time for the Form 5 assembly. If you do not have your January 2023 dosimetry yet, please check with your dosimetry custodian and contact DRS immediately if not found. 

As a reminder, anyone monitored for ionizing radiation exposure has the right to obtain their dose history at any time. If you wish to see your dose history anytime during the year, please contact the Dosimetry Program via e-mail at to make the request in writing. Your NIH exposure history will be sent to you within 30 days.



On December 5, 2022, the Department of Homeland Security announced an extension of the REAL ID full enforcement deadline to May 7, 2025. Learn more about the REAL ID Extension.​
