title: Assessment of the radiological safety of a Genoray portable dental X-ray unit.
abstract: OBJECTIVE
  The portable dental radiographic systems are generally used in emergency situations (e.g. during natural disasters) for disabled/aged patients and in patient rooms. This study assesses the output exposure of a portable dental radiographic system measured using thermoluminescent dosemeters (TLDs).
  
  
  METHODS
  Occupational exposure of the operator was determined when the portable dental unit was used for mandibular and maxillary teeth exposure.
  
  
  RESULTS
  The doses of some critical organs of an operator were measured using TLDs implanted within the Rando phantom.
  
  
  CONCLUSIONS
  Considering the annual organ dose limits, the eye lens dose limit is the main factor determining the frequency of system application.
