Abstract

Gonads, bone marrow and thyroid doses arising from seven x-ray examinations (11 projections) were calculated for 385 patients (185 male and 200 female), who were radiographed in x-ray department of Mashhad Ghaem Hospital.It is estimated that the highest gonadal dose of male patients was equal to 9.62±1.89mGy and resulted from pelvis (AP) examination. Lumbo saceral spine examination produced the highest gonad dose equal to 4.21±1.09mGy to female patients.Maximum bone marrow dose delivered to male and female patients were 3.53±0.62mGyand 2.88±0.73mGy respectively and were caused by lumbo saceral spine radiography.Cervical spine x-ray examination was responsible for highest thyroid dose of male and female patients. In this survey the corresponding values were 4.25±0.53 and 1.91±0.23mGy respectively.Estimated mean value of organ doses in this study were compared with the values reported by other researchers and also with the annual limits recommended by ICRP-60. Our estimated average doses to gonads and bone marrow of male and female patients from cervical spine and pelvic radiography are much higher than those reported by ICRP-60. This conclusion is also true for other surveys, this indicats that patient doses depend to various parameters such as: observation of radioation protection rules by radiographers, their skills and implementation of quality assurance programme. Any improvement of these parameters can reduce the doses to the levels recommended by ICRP.In this study all estimated organ doses are less than annual limits of 5mSv, except gonadal doses in pelvic radiography (AP) of male patients.
