Personnel Radiation Monitoring Requirements
The State of Tennessee requires that a person be monitored for radiation exposure if it is expected that the individual will receive a dose in excess of 10% of the annual occupational dose limits for a radiation worker, as listed below.
Annual Occupational Radiation Dose Limits for Adults
|Lens of the Eye||15,000|
|Skin; any organ except lens of the eye||50,000|
Pregnant radiation workers should refer to the Declared Pregnant Worker page for further information.
In support of efforts to keep occupational radiation exposure As Low As Reasonably Achievable (ALARA), the dosimetry badge program operates under an institutional ALARA Policy, which establishes criteria for dosimetry badge monitoring, dose assessment, and response to occupational radiation dosimetry badge results.
OCRS Radiation Safety reviews all dosimetry badge results and investigates high exposures according to the investigational level framework provided in the ALARA Policy. Each Radiation Safety Committee reviews a summary of radiation dose records either quarterly or biannually, depending on ALARA policy requirements.
Read your ALARA Policy:
Radiation Exposure Monitoring
Personnel dosimeters (badges) are provided to Vanderbilt radiation workers through OCRS Radiation Safety. Radiation Monitoring badges are issued commensurate with the type of ionizing radiation to which a worker is exposed. Badges are issued to workers who are likely to exceed 10% of the annual occupational dose limits. Workers may work with radioactive material or sources of ionizing radiation and not be issued a monitoring badge.
Radiation badges will be issued based on:
- an analysis of the individual’s potential radiation exposure,
- the type of radiation source,
- the nature and duration of exposure, and
- the quantity of radioactive material that will be handled at any one time.
Apply for a Badge
Radiation workers should submit a Radiation Worker Registration Form to their Departmental Badge Representative. All badged radiation workers must comply with the instructions outlined in the Responsibilities of Badged Radiation Workers. Furthermore, all radiation workers are obligated to know and adhere to requirements listed in the Radiation Safety Manual. Radiation workers should refer to Radiation Safety Training for information on required training.
Replace a Lost or Damaged Badge
If a badge is lost or damaged, contact your Departmental Badge Representative or OCRS Radiation Safety immediately. A replacement badge must be obtained to ensure completeness in the radiation worker’s occupational dose history record.
Radiation Dosimetry Records
Access Your Dosimetry Records
For current Vanderbilt radiation workers, dosimetry badge results are available online through the badge vendor’s website. Please refer to these instructions to access your individual dose report.
To obtain an official copy of your occupational radiation dosimetry report from Vanderbilt, complete and submit a signed Dose History Release Request to OCRS Radiation Safety. Vanderbilt must have the signature of the individual who was monitored in order to release that person's radiation exposure history record.
All radiation dosimetry correspondence may be mailed or faxed to:
Office of Clinical and Research Safety
A-0201 Medical Center North
1161 21st Avenue South
Nashville, TN 37232-2665
Fax: (615) 343-4951
Phone: (615) 343-8502
Interpretation of Reports
For help with dosimetry report interpretation, refer to the Radiation Dosimetry Report Explanation.
Departmental Badge Representatives
At Vanderbilt, groups that use radiation dosimeters are divided into badge series, or subaccounts, and are managed by a Departmental Badge Representative. Responsibilities of the Badge Representative include:
- Distribution and collection of badges at specified frequency (i.e., monthly, quarterly)
- Obtaining replacements for lost or damaged badges
- Requesting administrative changes to radiation worker or badge series account
- Maintaining radiation dosimetry reports
For further information, Badge Representatives should refer to the Radiation Badge Representative Guide.
- Radiation Worker Registration Form
Must be completed before the badge can be assigned. See also Radiation Badge Responsibilities.
- Dose History Release Letter
One letter must be completed for each institution at which you received occupational exposure to radiation.
- Declaration of Pregnancy Form & Information
This form must be completed to be eligible for the lower occupational radiation exposure limits for the fetus/embryo of a Declared Pregnant Worker (DPW).
