Radiation Safety Requirements for Persons Using Radiation Producing Machines


 Those authorized by the North Carolina Baptist Hospitals, Inc., to operate diagnostic radiation-producing machines are required to comply with the following list of regulatory standards and good health physics practices. All occupationally exposed workers should make every effort to maintain their radiation exposure
As Low As Reasonably Achievable (ALARA).


The following procedures should be followed:

Always be aware of the location of your hands with respect to the x-ray beam. Never place your hands in the useful beam (or primary beam).

  • An x-ray worker should not hold a patient or a film except in an emergency [Rule .0603(a)(1)(H)(i)].
  • The operator is responsible for clearing the x-ray room of non-essential people before generating x-rays [Rule .0603 (a)(1)(E)].
  • Keep dosimeters dry, contamination-free, and away from sources of extreme heat and radiation sources when not worn.
  • The operator of a mobile unit should stand at least six feet from the patient and well away from the useful beam.
  • Whole body dosimeters should be worn as follows:
    • Single-badge workers – on the collar, outside lead apron
    • Double badge, pregnant female radiation worker – regular badge on the collar, outside lead apron and a fetal badge at abdominal region (at waist) under lead apron.
  • If you are issued a finger ring dosimeter, wear it on the hand most likely to receive the highest dose.
  • Wear your assigned dosimeter (Luxel) any time you work with or near radiation-producing machines. It is a good idea to wear your dosimeter throughout the workday. Do not take it home since that will increase the chances of misplacing it or throwing it in the laundry.
  • If your dosimeter is exposed to radiation, becomes contaminated with radioactive materials or is exposed to a radiopharmaceutical that your physician gave you for a nuclear medicine scan, inform the Office of Environmental Health and Safety – Radiation Safety
  • To expedite the reporting process, exchange dosimeters during the first week of each exchange period. It is very important to turn in your dosimeter promptly so that accurate readings of the exposure levels can be obtained and problems can be identified. Contact your department’s dosimetry coordinator or your EH&S departmental radiation safety advisor for additional information.
  • A dosimeter that is lost or returned damaged will result in a dose estimate being made and added to the worker’s exposure record.
  • If you work with radiation sources outside Wake Forest School of Medicine, be sure to contact the Environmental Health and Safety – Radiation Safety operations, so a total exposure dose for the year can be tracked.

If you have a question or concern, call the Office of Environmental Health and Safety –Radiation Safety at 716-1201.
