| Abstract:: |
| Objective To investigate the entrance surface doses to the patients undergoing diagnostic X-ray examinations in Guangxi. Methods A total of 2236 patients who have received diagnostic X-ray examinations were investigated at 25 randomly selected hospitals at different levels where dthermoluminescence dosimeters were used to measure the entrance surface doses in different hospitals with different equipment and different positions. Results The entrance surface dose from X-ray imaging, computed radiography (CR) and digital radiography (DR) were in the range of 0.08-31.51, 0.11-4.25 and 0.05-35.63 mGy, respectively. The entrance doses to abdomen (AP), pelvis (AP), head (LAT), head (PA), chest (PA), chest (LAT), thoracic vertebra (AP), thoracic vertebra (LAT), lumbar vertebra (AP), lumbar vertebra (LAT) were 0.08-19.53, 0.15-18.78, 0.08-9.87, 0.06-9.24, 0.05-2.71, 0.13-2.93, 0.15-19.01, 0.07-25.33, 0.16-27.23, and 0.11-35.63 mGy, respectively. Conclusions The average dose to patients from X-ray diagnosis in Guangxi was in accordance with the relevant standards, but DR could partly lead the chest (PA) dose to exceed the guidance levels of medical exposure. |
