Registering Radiation Workers
If you are using radioactive materials or radiation producing machines, please complete the Radiation Worker Registration Form [PDF] and submit it to the Radiation Safety Office at radiation.safety@drexel.edu. The Radiation Safety Office will use this to determine training and personal radiation monitoring requirements, if any.
