Abstract
OBJECTIVES: 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.
