[en] Objective: To investigate the incident body surface dose level of subjects caused by X-ray examinations in Jiangxi province in 2017, and to elaborate the current situation of medical radiation of X-ray diagnosis in Jiangxi province. Methods: 20 hospitals were randomly selected from 6 prefecture-level cities, Nanchang, Shangrao, Ganzhou, Pingxiang, Yichun and Jiujiang to measure ESD values of different irradiation sites of 1 273 examined individuals by using thermoluminescence dosimeters. Results: In 2017, the ESD values range of subjects caused by computer X-ray photography (CR) and digital X-ray photography (DR) in Jiangxi province was 0.08 ∼ 17.81 mGy and 0.04 ∼ 30.91 mGy, respectively. The entrance surface doses to adult patients from X-ray examinations were 0.07 ∼ 2.40 mGy for chest AP, 0.13 ∼ 7.27 mGy for chest LAT, 0.33 ∼ 23.29 mGy for lumbar spine AP, 0.62 ∼ 30.91 mGy for lumbar spine LAT, 0.09 ∼ 1.69 mGy for cervical spine AP, 0.10 ∼ 1.79 for cervical spine LAT, 0.29 ∼ 23.46 mGy for pelvic and hip joint, respectively. Conclusion: 75% percentile of ESD to chest LAT was higher than the guidance levels of medical radiation exposure. The ESD values of some exposed parts decreased significantly compared with the survey during the 9 th National Five-Year Plan period. The ESD values caused by DR photography is higher than CR, and measures should be taken to reduce the radiation dose of subjects caused by DR photography. (authors)
