title: Characterization of optically stimulated luminescence dosemeters to measure organ doses in diagnostic radiology.
abstract: OBJECTIVE
  The aim of this study was to assess the characteristics of an optically stimulated luminescence dosemeter (OSLD) for use in diagnostic radiology and to apply the OSLD in measuring the organ doses by panoramic radiography.
  
  
  METHODS
  The dose linearity, energy dependency and angular dependency of aluminium oxide-based OSLDs were examined using an X-ray generator to simulate various exposure settings in diagnostic radiology. The organ doses were then measured by inserting the dosemeters into an anthropomorphic phantom while using three panoramic machines.
  
  
  RESULTS
  The dosemeters demonstrated consistent dose linearity (coefficient of variation<1.5%) and no significant energy dependency (coefficient of variation<1.5%) under the applied exposure conditions. They also exhibited negligible angular dependency (≤ 10%). The organ doses of the X-ray as a result of panoramic imaging by three machines were calculated using the dosemeters.
  
  
  CONCLUSIONS
  OSLDs can be utilized to measure the organ doses in diagnostic radiology. The availability of these dosemeters in strip form proves to be reliably advantageous.
