The walls of the outpatient radiology department of the physical examination center of the general hospital have to undergo special treatment, such as lead plate, lead glass, lead door and barium sulfate sand. In addition, it also includes lead ingots, lead bricks, lead screens, industrial detection doors and other lead products. Lead glass, protective coating, radiation protection door, window and other materials meet the national standards and have the inspection report of radiation protection equipment issued by the competent department of health administration. All lead products are made of more than 99.99% lead ingots, and the lead ingots are made of 1 × lead (more than 1300% of the national standard).
I. brief introduction and requirements of Dr room
At present, the scanning room of Dr machine room covers an area of about 32 ㎡ (subject to the actual measurement). The brick wall is required to be painted with radiation protection coating. The walls adjacent to the scanning room and the operation room need to be made with protective partition walls. The outer surface of the radiation protection door is generally made of stainless steel or aluminum-plastic plate with beautiful appearance and radiation proof signs to remind the staff to pay attention to safety. The design of Dr room machine room requires two protective doors: one electric protective sliding door, with the specification of 1200 * 2100mm hole and 1500 * 2200mm door body. One protective open door, specification 800 * 2100mm and one north wall protective window, specification 1000 * 900mm. The specification of lead glass provided by our company is 1200 * 800mm.
According to the above requirements, combined with the actual situation of the site investigation, provide complete technical data (design and construction scheme).
II. Technical requirements for protective materials in Dr room
The equipment and materials comply with the current basic standards for the safety of ionizing radiation and radiation sources (GB 18871-2002), health protection standards for medical X-ray diagnosis (GBZ 130-2002), health protection monitoring standards for medical X-ray diagnosis (GBZ 138-2002), health management measures for radiation protection equipment and radioactive products, and other relevant national standards and specifications.
1. Radiation protection door:
① adopt steel structure frame (lead equivalent according to the design protection standard, strictly control the quality), solid steel frame combination, open and pull flexibly and easily. It is required to select the integrated aluminum alloy door frame, and the radiation protection effect meets the GB18871-2002 standard. Long term use, no deformation, no rust, no solder joints, beautiful and generous. Hinges shall be reinforced.
② the exterior surface is decorated with anti-static plastic spraying steel plate or stainless steel plate with a thickness of more than 0.85mm.
③ equipped with door interlock device and working warning light above the door.
④ the door is equipped with special ionizing radiation warning signs.
⑤ electric protective door: professional automatic door machine, equipped with infrared induction and anti pinch device to ensure low failure rate. The protective door can be opened and closed manually in case of power failure.
2. Radiation protection coating:
Our company specializes in the production of composite protective coating, with the raw material processing and production capacity of various particle types and high and low specific gravity of barium sulfate. The use of barium sulfate protective coating complies with the regulations of the Ministry of health of the people's Republic of China order "measures for the health management of radiation protection equipment and radioactive products", with the characteristics of strong ray blocking ability, firm bonding, stable lead equivalent, etc.
3. lead plate:
There are two common methods for lead plate protection:
I. the lead plate is built into the wall, which is rarely used. The main reason is that most of the protection construction is based on the purpose of the room after the house is built, and most of the protection rays are not considered when the house is built.
II. The keel frame shall be made on the original wall according to the size of the lead plate, and the lead plate shall be fixed on the wall. The joints shall be staggered to prevent radiation leakage. The lead plate used shall not have sand holes, uneven and other phenomena. The space left by keel installation of lead plate is about 2.5 times of the thickness of lead plate, which is convenient for the welding staggered position of joint to be a little thicker; finally, after the lead plate is installed, a layer of decorative wall can be installed on the surface (multiple materials can be used for beauty).
