Whether to perform X-ray examinations on children should be analyzed and judged based on actual clinical needs and protection principles, and X-ray examinations can only be applied for when there are legitimate reasons. 6.2 When diagnosing children, non-ionizing radiation examination methods should be given priority. 6.3 When performing orthopedic reduction and removing foreign bodies under X-ray fluoroscopy, continuous exposure is prohibited and attention should be paid to shortening the exposure time as much as possible. 7 Requirements for X-ray workers
7.1 Must be proficient in pediatric radiology business technology and radiation protection knowledge, carefully review whether each application for children's X-ray examination is reasonable, and have the right to refuse X-ray examinations without legitimate reasons. 7.2 In addition to clinically necessary X-ray fluoroscopy, children should be examined by X-ray photography. 7.3 Before fluoroscopy, sufficient dark adaptation must be done, and small irradiation field fluoroscopy technology should be used during fluoroscopy. 7.4 When performing X-ray photography on children, the irradiation field should be strictly controlled to limit the useful beam to the range of actual clinical needs. The irradiation field area should generally not exceed 10% of the film area. 7.5 When performing X-ray photography on children, short-exposure photography technology should be used. 7.6 When performing X-ray photography on infants and young children, filter grids should generally not be used. 7.7 When performing X-ray examination on children, attention must be paid to the protection of non-examination parts, especially the shielding protection of gonads and eye lenses should be strengthened. 7.8 When using mobile equipment to perform X-ray examinations in wards or nurseries, protective measures must be taken to reduce the exposure of surrounding children, and it is not allowed to direct the useful beam toward other children. 7.9 Children shall not be used for teaching and research cases of X-ray examinations without special permission. 7.10 When performing X-ray examinations on children, equipment that fixes the child's position should be used.
