Shielded stainless steel lead safe containers (commonly referred to as lead pots, lead boxes, or radioactive waste shielding containers) are critical protective devices used for the safe storage and transport of radioactive materials in fields such as nuclear medicine, radiotherapy, and industrial radiography. The outer casing is primarily constructed from 304 medical-grade stainless steel or cold-rolled, corrosion-resistant steel plate, though some small portable units utilize high-strength engineering plastics. These containers are customized based on the type and activity of the stored radionuclides, with lead-equivalent shielding typically ranging from 1 mm Pb to 10 mm Pb or higher. Featuring smooth, corrosion-resistant, and fingerprint-resistant surfaces that are easy to clean and disinfect, they meet medical cleanroom standards. Their core design aims to effectively attenuate ionizing radiation through high-density materials while ensuring operator safety and environmental compliance.
1. Lead-Equivalent Calculation: Radiation energy must be taken into account (e.g., 3mm lead plating suffices for energies below 100kV, whereas 5mm is required for those above 150kV); additionally, a 20% safety margin should be included.
2. Physical Specifications: 304 stainless steel is recommended for the casing material (due to its rust and corrosion resistance), and laser welding should be used for seams to ensure zero radiation leakage.
3. Compliance: Test reports must be provided for all lead boxes; the lead content must meet the standard for >99.994% pure lead to prevent radiation attenuation issues caused by lead alloys.
