Requirements for thickness of useful wire harness for headless photography in dental panoramic machine room

For the dental panoramic machine room, the thickness of the useful wire harness for seamless photography should be not less than 1mm lead. According to relevant data, the useful beam direction of dental dental dental film room and dental panoramic room (without skull photography) is not less than 1mm lead equivalent thickness. The room (irradiation room) of oral X-ray equipment should give full consideration to the protection and safety of personnel in adjacent rooms (including upstairs and downstairs) and surrounding places. There should be an independent computer room to meet the space requirements for using equipment. Shielding protection requirements for different types of dental X-ray equipment rooms: the equivalent thickness of lead in the useful beam direction of dental CT and dental panoramic room (with head photography) shall not be less than 2mm, and the equivalent thickness of lead in the useless beam direction shall not be less than1mm.. The equivalent thickness of lead in the useful beam direction of dental film machine room and dental panoramic machine room (excluding head photography) is not less than 65438±0mm, and the equivalent thickness of lead in the useless beam direction is not less than 65438±0mm. The wall of the computer room should have a protective thickness of 1 ~ 1.5mm lead equivalent. The positions of doors, windows and pipe openings of the machine room should be set reasonably, and the doors and windows of the machine room should have the same protective thickness as the wall where they are located. The ceiling and floor of the machine room (excluding the top floor) located in the multi-storey building (excluding the building below) shall meet the shielding thickness requirements of the corresponding irradiation direction.
