Personal radiation monitoring and protective devices are available. Operators are
urged to use them to protect against unnecessary radiation exposure.
It is important that Operators and their supervisors be fully acquainted with
applicable government radiation protection regulations. Many provisions of these
regulations are based on recommendations of the National Council on Radiation
Protection and Measurements. Recommendations for medical x-ray protection are
published in NCRP Report Number 102, and are available from:
