How to do the radiation protection project in the radiation room? Requirements for radiation protection doors

The workplace of radiologist or technician includes X-ray room, control room and film processing room. These studios must be adequately shielded to ensure the safety of radiation diagnostic workers.

1 X-ray machine room

1. Radiation protection of computer room walls

Solid clay brick walls are generally used, and thick core waste brick walls can also be used. However, it is necessary to pay attention to the fullness of mortar without leaving gaps when bricklaying, but it is difficult for actual construction personnel to do so when bricklaying. Therefore, barium sulfate sand with the thickness of 1.5-2 cm can be applied to the brick wall to make up for the defects of brick joints, and it is necessary to avoid the wiring harness facing the operation room when placing seats in the computer room. If there is no compartment operation, a movable protective screen with lead equivalent of 1mm can be equipped for exposure after shooting.

2. Windows and doors of computer room

Computer room doors and windows should be equipped with 1mm lead equivalent shielding protective layer. If the height of the protective window is 2m from the ground, the protective window can also be an ordinary window. Outside the protective door, there should be red warning lights, warning signs of ionizing radiation and warning information prompting pregnancy, and the closed exposure protection regulations should be strictly implemented to ensure the safety of people waiting outside the door and other types of work.

3. Suggest the operating room

If there is only one 24-square-meter X-ray machine room for fluoroscopy and filming, a simple operation room can be made in the corner of the machine room, using protective materials with lead equivalent of 1 mm, and a lead glass observation window with appropriate size and thickness can be assembled on the room wall facing the X-ray machine. Or customize a room to shoot the main character.

4. The National Standard for Ventilation of Computer Rooms stipulates that computer rooms should be well ventilated. Different forms of mechanical ventilation can be selected, or natural ventilation can be enhanced by using the louver air inlet and movable louver at the bottom of the protective door. Generally keep breathing 3-4 times per hour.

5. Layout of computer room

Sundries unrelated to diagnostic work shall not be piled up in the computer room. In the hospital outpatient fluoroscopy room, the waiting position of the patient should be reasonably selected and the corresponding protective measures should be taken.
