11.1 General Guidelines and Requirements

  • All X-ray machines must be registered with EHS.
  • EHS requires the submission of a room plan and equipment specifications for each new installation of a unit.
  • The medical use of X-ray machines is permitted only by or under the prescription of a licensed practitioner or advanced registered nurse practitioner who meet the requirements specified by the UIHC By-Laws.
  • The medical use of fluoroscopic equipment is permitted only by or under the direct supervision of a licensed practitioner who meets the requirements specified by the UIHC By-Laws.
  • Only certified X-ray technologists who meet the regulatory requirements as a diagnostic radiographer as specified in the Iowa Administrative Code (IAC) 641- Chapter 42 may operate X-ray machines for medical use under the supervision of a licensed practitioner or advanced registered nurse practitioner.  Certified X-ray technologists are required by regulation to post their State of Iowa permit to practice.  No X-ray certification or permit to practice is required for operators of dual energy X-ray bone densitometers (DEXA).  DEXA operators are required to complete bone densitometry training provided by the manufacturer or an equivalent.
  • Operators of dual imaging systems such as SPECT/CT or PET/CT must meet the requirements specified in the Iowa Administrative Code (IAC) 641- Chapter 42, Paragraphs 42.2(7) and 42.2(9).  For assistance contact the Radiation Safety Officer at 335-8501.
  • Adjust diagnostic radiographic procedures and CT protocols to minimize radiation doses to pediatric patients.
  • Lead aprons or whole body protective barriers are required by regulation to be used by all staff continuously present in the room during the use of an X-ray unit.  The lead aprons or protective barriers must contain at least 0.25 mm lead-equivalency to protect against scattered radiation.  Aprons with a lead-equivalency of 0.5 mm are required for individuals receiving direct beam exposure.  DEXA units do not require the use of protective barriers or aprons.  However, DEXA unit operators and ancillary personnel are required by regulation to remain at least 1 meter from the unit during operation.
  • When using mobile or portable X-ray units notify the individuals present to clear the room prior to making an exposure.  Patients who cannot be moved out of the area must be protected from scatter radiation by using lead aprons or by moving them to a distance of 2 meters from both the tube head and the nearest edge of the image receptor.
  • When a patient or film requires auxiliary support during a radiographic procedure, mechanical holding devices should be used whenever possible.
  • No individual shall be routinely employed to hold patients and film.
  • Personnel or members of the patient’s family that volunteer to hold patients must wear lead protective apparel of the required lead-equivalency to protect against scattered radiation or direct beam exposure as applicable.
  • Wear assigned personal dosimeters while operating X-ray units or assisting in radiographic procedures.
  • Use all protective devices supplied with the X-ray unit whenever possible.
