Evaluation of status of radiography sections: radiation protection and imageʹs quality

An important goal in radiography is to obtain the best image by delivering the least radiation dose to the patient. There is no doubt that by implementing radiation protection regulations, the radiation dose which received by the patient can be controlled. Reduction of image quality may cause repetition of X-ray examination which in turn leads to extra and unnecessary radiation dose to the patient. This study was an attempt to evaluate the status of 51 radiological centers according to some parameters affecting the quality of images and the radiation dose delivered to the patient. The concerning factors were X-ray department radiation safety, condition of dark room and operation of film processor according to standards, availability and proper use of safety shields and radiation warning signs, technician knowledge and practice of self and patient protection. Our investigations showed that these centers had neither standard dark room nor proper warning signs There was no record or any type of proper archive related to radiation protection of staff in 89% of these centers. About 82% of X-ray rooms and 77% of preventive covers had some faulty sections and 37% of them had radiation leakage. This investigation has shown that a great number of X-ray departments throughout the country practice without proper supervision. On the basis of these findings regular monitoring of x-ray departments and implementing radiation protection regulation are recommended.
