To meet DOE requirements, the Dosimetry Department must have all orange 4th quarter 2025 dosimeters returned by close of business Jan. 8.
If you are going to be gone the last week of December 2025 and/or first week of January 2026, leave your 4th quarter dosimeter with your project dosimetry point of contact or the Dosimetry Office located at 100 Union Valley. You can pick up your blue 1st quarter CY 2026 dosimeter when you return.
Workers may be restricted from entering radiological areas managed by UCOR for failing to return their previous quarter dosimeter by the deadline. If you have workers who are out for short-term disability, please contact the Dosimetry office at UCORDosimetry@orcc.doe.gov as soon as possible so we can send them mailers to return their dosimeters early.
Individuals issued a dosimeter are responsible for ensuring their dosimeters are exchanged at the beginning of every quarter (i.e., the first business day of the quarter).
If you have not been contacted for dosimetry distribution by the third business day of the new quarter, contact your project management, Field Radiological Protection Manager, or UCOR Dosimetry personnel at UCORDosimetry@orcc.doe.gov about exchanging your dosimeter.
If you have questions related to this notification, contact:
