Radiation protection: (1) When the photosensitizer dose is sufficient, the distance from the focus to the skin shall be increased as much as possible so that on the one hand, X-ray radiation on the patient can be reduced and on the other hand, image distortion can be reduced (2) During the loading process, the operator shall operate meters away from the tube head and shall not stand in the X-ray radiation direction The operator must use a protective device and wear protective clothing If the local health sector has stipulated that it is necessary that an engine room and relevant protective facilities shall be provided, it shall be carried out according to the provisions of the local health department; (3) In the event of an unexpected emergency, e.g., when the power switch is turned on or the Exposure button is pressed, the exposure indicator is lit constantly or the buzzer keeps buzzing, the power switch shall be turned off immediately to prevent radiation or machine damage (4) Test method of radiation dose when the equipment is working: when it is running (70 kV, mA, 2.000 s, 20 times) under nominal voltage of X-ray tube with the maximum input energy equivalent to the specified 1h, at 1m from the focal spot, and the average air Kerma rate does not exceed 0.25 mGy/h within any area of 100 cm² (the main linear size is not longer than 200 mm) 22 (5) If the operator operates the equipment outside the clinic room, it is recommended to install radiation-proof visible window or video equipment and audio equipment, so that the operator can see the patient and communicate with him/her Safety and use: Attention: Dental X-ray film shall be purchased and used by professional physicians at their own discretion The dental X-ray film used shall meet the requirements of national standards with the record certificate of Class I medical equipment 2.7 Place the dental film According to the photographed tooth position of the patient, place the dental film
