What is the required thickness of secondary barrier walls?

The required thickness of secondary barrier walls is 0.8 mm of lead thickness. Secondary barriers are designed to protect against scattered radiation and also account for any leakage from primary radiation sources. The thickness is determined based on the need to adequately reduce exposure to radiation in areas adjacent to the radiographic procedure room.

This specification is grounded in the principles of radiation protection, ensuring that individuals in non-radiation work areas are kept safe from unnecessary exposure. The 0.8 mm lead thickness provides sufficient attenuation for the scattered radiation that might occur during the use of X-ray equipment, aligning with established safety standards and guidelines in radiologic practice.
