The mother-and-child lead door is specially designed for high-radiation protection scenarios and is widely used in hospital radiology departments, nuclear medicine laboratories, industrial flaw detection rooms, scientific research institutions and other places, taking into account both safety protection and ease of use.
1. Structural design
The "mother-and-child door" structure (main door + sub-door) is adopted. The main door meets the needs of large equipment or multiple people to pass through, and the sub-door provides convenience for daily personnel to enter and exit, reducing the energy loss and radiation leakage risk caused by frequent opening of the main door. The thickness of the door body is usually 50-200mm, which is customized according to the protection level. The interior is filled with high-purity lead plate (lead equivalent 2-10mmPb), and the outer layer is reinforced with high-quality galvanized steel plate or stainless steel to ensure the stability of the overall structure.
2. Protection performance
The lead plate adopts seamless welding technology, combined with multi-layer shielding design, to effectively block X-rays, gamma rays and neutron radiation, and the leakage radiation dose rate is strictly controlled within the national protection standard (such as GBZ 130-2020). The door seam adopts a stepped overlapping structure or a labyrinth sealing technology, with anti-aging silicone sealing strips to achieve "zero leakage" of radiation.
3. Intelligent configuration
Supports electric/manual dual-mode drive, optional infrared sensing, door interlock, emergency stop button and other safety devices to ensure that the equipment automatically powers off when the door is opened to prevent misoperation. Some high-end models are equipped with touch screen control, remote monitoring and fault alarm functions, suitable for intelligent medical and industrial scenarios.
4. Durability and adaptability
The surface of the door body is treated with anti-corrosion spray or brushed stainless steel, acid and alkali resistant, scratch-resistant, and adaptable to complex environments such as humidity and clean rooms. The track adopts a heavy-duty load-bearing design, supports frequent opening and closing, and has a lifespan of more than 100,000 times. Supports non-standard customization, and can adapt to curved walls, ultra-wide door openings (maximum span 6m) and special radiation protection requirements.
5. Installation and service
Provide professional measurement, solution design and on-site installation guidance to ensure seamless fit between the door body and the wall. The warranty period is usually 3-5 years, and lifelong maintenance support is provided to ensure long-term and safe use by users.
Summary: With modular design, high-level protection and intelligent control as its core advantages, the mother-and-child lead door is an efficient solution in the field of radiation protection, taking into account functionality, safety and long-term economy.
