Personnel Dosimetry

Duke employees who work with radiation sources or radioactive materials may be required to wear a personnel dosimeter ("film badge"). The criteria for issuing a dosimeter are based upon regulatory compliance considerations and individual circumstances. Decisions about monitoring individuals or groups are made by the Radiation Safety Officer.

Dosimeter Requests and Special Cases

Here are three ways you can request a dosimeter:

  • Fill out the online request form on our Dosimetry Registry. After you log in, click the "Request Film Badge" button and fill in the electronic form. Your data will be sent directly to Radiation Safety, along with an automatic email notification.
  • Download and print a Personnel Dosimeter Request and Radiation Exposure History Release* form. Email your completed form to
  • Contact us via phone at (919)684-2194 or email at, or if you have other questions about our personnel dosimetry program.
Lost Dosimeter

If you lose your dosimeter, contact us obtain a replacement as soon as possible. Do not wear another person's dosimeter, and do not wear a dosimeter marked as a "Control". If a replacement dosimeter is not needed immediately, you can download a Certificate of Lost Badge* form, and return it to us via email.

Monitoring By Previous Employers

If you have been monitored for radiation exposure at any other employers during the current calendar year, Duke is required by regulation to obtain your radiation exposure history from those employers. Download a Radiation Dosimeter Request and Radiation Exposure History Release* form and return it to us via email or regular mail (Radiation Safety Division, Box 3155, Duke University Medical Center, Durham, NC 27710).

Pregnancy Declaration and Fetal/Embryo Monitoring

It is recommended that pregnant radiation workers formally declare pregnancy and receive appropriate radiation safety consultation as early as possible. Duke Employee Occupational Health and Wellness (EOHW) collaborates with the Radiation Safety Division to ensure that declared pregnant workers have radiation exposures below regulatory limits during the period of gestation. 

Contact EOHW for an appointment (or walk in) to voluntarily declare your pregnancy and set up a confidential radiation safety consultation about your occupational exposures at Duke.
