title: Interventional Radiologists: a Necessary Evaluation of Technical, Protective and Technological Operation.
abstract: OBJECTIVE
  To present the results of occupational radiation doses investigated through a Hospitals of Mazandaran Medical Science Universities in north of Iran. Radiology unit has an important role in diagnosis of many disorders with providing suitable and high quality pictures. A good picture was provided using correct technical criteria and suitable circumstance of patient. Finally, operation and knowledge of radiology personnel directly has a primary role in determining quality of radiography.
  
  
  METHODS
  This study was done in order to determine personnel operation in the units of hospitals radiologist related to University of Mazandaran Medical Science. Data collection tools are made of a researcher check list that was used after obtaining suitable letter and validity indexes. All of the 73 personnel of radiology unit related to Mazandaran Medical Science were studied. 35 operations (in technical, protective and technological fields) of any personnel, in three distinct shifts were observed and recorded. All of them were tested regarding these three fields with a total of 40 questions.
  
  
  RESULTS
  The total scores received from personnel in technical part in the morning, evening and night shift were 66.4, 53.9 and 60.2 percent respectively. Received scores from personnel in the protective fields were 68.1, 59.5 and 60.2 percent. Moreover, received scores from personnel in the technological operation fields were 47.8, 39.95 and 43.65 percent respectively. Comparison of these three scores in technical, protective and technological operation fields showed a meaningful difference (p<0.05).
  
  
  CONCLUSIONS
  The overall quality of personnel operations were nearly desirable and in need of continuous education, supervision and evaluation. Emphasizing protection to beams, accessibility of necessary tools, continuous supervision regarding the usage of these equipments and respecting the other security points have an important role in decreasing patients absorbed doses.
