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

Lost Dosimeter

If you lose your dosimeter, contact us to 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.

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.
