Occupational exposure of apprentices in radiology in the field of professional training

The good economic moment of our country has been providing an increase of courses in technical and technological area mainly in the field of radiology, which has raised the number of apprentices in the field of stage in clinics and hospitals. However, the shortage of placements and the fact that many of these students are workers, has forced the institutions of technical education to seek alternatives for the students to meet the workload of the stage in a time as short as possible. For this reason, often the students are obliged to comply with up to 10 hours of internship in a single day, in companies that often are not in accordance with the standards of radiological protection. What has worried the authorities of Goiania, because they believe that this exposure can raise the dose received. It is known that every person who works with X-ray diagnostics should use, during their work day and while stay in controlled area, individual dosimeter reading indirect, changed monthly. However, in practice these apprentices do not use the meter for monitoring of doses in probationary period. In This way, we measure the doses received us trainees using monitors TLDs in the thoracic region with and without plumbiferous apron on stage with total workload of 150 hours, performed daily from Monday to Friday for 6 hours per day during 5 weeks and performed to Saturday and Sunday for 10 hours daily in 7.5 weekends, with X-ray equipment conventional. The results reveal that in none of the cases the dose reached the value of 0.2 mSv, which is the minimum limit of reading dosimeter. We conclude then that the stages of weekends, taken the preventive measures of radiological protection are safe and can be performed without any prejudice with regard to the dose received, when compared to those of lower daily hourly load.
