Lead Box
Strong radiation protection: High-density lead effectively shields X/γ rays, suitable for medical and nuclear industries.
Corrosion resistance: Acid, alkali and moisture resistance, long-term storage of chemicals.
Impact resistance: High-density structure protects precision instruments.
Good sealing: Isolate air and moisture, preserve cultural relics or specimens.
High cost performance: The cost is lower than that of metals such as tungsten, economical and practical. Lead boxes are ideal for radiation protection and special storage.
Medical lead boxes are specially designed for safe storage/transport of radioactive drugs (such as technetium [99m⁺ᶜ], iodine [¹³¹I]). They are lined with high-purity lead (≥0.5mmPb equivalent) to effectively shield γ/X-rays and meet protection standards. The exterior is made of stainless steel or carbon steel, which is corrosion-resistant and impact-resistant. They are equipped with sealing covers, dose monitoring labels and lock buckle designs, which comply with GBZ 133-2002 and ISO 2919 standards, ensuring zero leakage in operation and ensuring the safety of nuclear medicine diagnosis and treatment.
1. Customization of material properties
Lead-based optimization: Select lead purity (above 99.99%) and thickness (1-20mm) according to the protection level. For example, nuclear waste storage requires ≥10mm high-purity lead layer, while medical equipment often uses 3-5mm.
Composite reinforcement: Combine steel, aluminum or polymer materials (such as polyethylene) to form a sandwich structure, taking into account lightweight and shielding effectiveness; lead rubber composite materials can improve flexibility and are suitable for wearable protective equipment.
Environmental protection and safety: Use lead alloy surface coating technology or low-toxic coating to reduce the risk of direct lead exposure and adapt to sensitive areas such as food and medicine.
2. Enhanced protection performance
Multi-radiation protection: Customize boron polyethylene interlayer or tungsten alloy lining for different radiation types such as X/gamma rays and neutron flow to improve comprehensive shielding efficiency.
Dynamic sealing: Double-layer sealing design (lead + silicone/fluororubber) combined with inert gas filling ensures zero leakage of radioactive substances or corrosive liquids to meet the storage needs of high-risk chemicals.
3. Functional and structural innovation
Intelligent module integration: built-in temperature and humidity sensors, radiation monitors or GPS positioning modules to achieve real-time transmission of environmental data and remote early warning.
Lightweight design: aluminum alloy frame supports thin lead layer, or honeycomb structure weight reduction technology, the overall weight is reduced by 30%-50%, which is convenient for laboratory or field transportation.
Layering and earthquake resistance: removable compartments with EVA cushioning pads protect precision instruments, cultural relics or biological samples from vibration and oxidation.
4. Application field adaptation
Medical nuclear industry: sterile lined lead boxes store radioactive drugs; nuclear power plant special anti-aging coating lead boxes encapsulate high-radiation waste.
Cultural relics protection: constant humidity and constant temperature lead boxes preserve ancient books, silk and other fragile cultural relics, isolating microorganisms and moisture erosion.
Industrial transportation: X-ray flaw detection equipment customizes open and close lead cabins, and transport lead boxes are equipped with anti-collision shells and smart locks, which meet international safety standards (such as IAEA).
Advantages and Trends
Customized lead boxes break through traditional limitations and achieve a balance between radiation protection, sealing safety and portability through the integration of material innovation and intelligent technology. At the same time, they promote environmental protection and automated management, becoming the preferred solution in the field of high-risk protection and precision storage.
