Technician Protection
• (1) Radiation monitoring - all x-ray x
technicians wear a dosimeter, which
monitors radiation received by the technician, , the t
results are recorded and
kept permanently
• (2) Radiation standards. . For the technician operating a dental x-ray x
machine,
the level of radiation must not ever exceed a maximum dose
• (3) Protective booth and shields - rooms require a shielding thickness of 5mm
barium sulphate which absorbes the radiation.
The timer switch is mounted outside the protective shielding to prevent the
operator from standing inside the booth during exposures. Leaded glass on
the booth or shield provides a continuous view of the patient during the
exposure. Holding
of the film or tube head by the x-ray x
