Radiation-proof barium sulfate construction

How does barium sulfate protect against radiation

Barium sulfate, also called barite, has been widely used in health centers, mainly to prevent radiation damage to limbs. The rule is that barium sulfate possesses mechanical properties that absorb X-rays.

CT room The percentage and construction method of radiation-proof barium sulfate

Barium sand: Shimin soil = 4:1, apply in batches, apply 1 cm each time, four times It\’s done, enough to solidify and reinforce the net inside.

What is the percentage of barium sulfate:cement block:sand in the anti-corrosion wall of the X-ray room?

Shengdun Medical Technology Co., Ltd. http://www.shengdunmt.cn / Barium sulfate sand and aerated cement are mixed at a ratio of 4:1 (4 parts barium sulfate + 1 part cement block) and are drawn on the wall or floor. The thickness is thin and the wall is lifelike. It only needs 15mm. Yes, the floor is 20mm. It is also sufficient to use lead plate for protection (1-2mm thickness is enough). Lead sliding door: the lead equivalent is 3 equivalents. Observation window: wired glass thickness is up to 15mm.

CT room, visiting room—the wall is notA lead plate (thinnest 3mm) must be used as a radiation barrier, and the floor can be coated with 40mm of barium sulfate + aerated cement in a ratio of 4:1. Shengdun Medical Technology Co., Ltd. http://www.shengdunmt.cn/ Lead School Gate: The chemical equivalent of lead must reach 4-5 equivalents. Observation window: The thickness of lead glass must be up to 20mm.

The original prevention of X-ray machines: the original appearance and health of X-ray machines are the most important part of X-ray prevention. The bulb cover and shield should not leak radiation, and the window should be equipped with an aluminum filter plate. The air radiation rate where the wire harness enters the patient\’s skin should not exceed 6R/min. Especially when using a bed tube for fluoroscopy, if the X-ray tube and its accessories have radiation leaking out, the staff and patients will be exposed to first-hand radiation.

Efforts should be made to shorten the radiation time of X-rays. Before getting involved in surgery, strict operating procedures should be formulated, relevant information about the diseased patient should be obtained, and the exposure of the snake\’s feet should be minimized. Shengdun Medical Technology Co., Ltd. http://www.shengdunmt.cn/ The total exposure time during the operation should not exceed 30 minutes, and the upper and lower illumination criteria should be optimized to avoid re-radiation.

Adopt to improve the separation between the surgeon and the radiation source (i.e., the tube tube) and the scatterer (i.e., the subject of reflection), reduce the radiation dose received by the surgeon, and deviate from each When the exposure is doubled, the radiation dose decreases by 3/4. During the exposure, the surgeon and key assistants should stay away from the X-ray radiation source.

Install a shield between the radiation source and the worker to reduce or eliminate the radiation exposure. If the shield is equipped with lead clothing, lead apron, lead cap, Lead glasses, lead gloves, etc. Shengdun Medical Technology Co., Ltd. http://www.shengdunmt.cn/
