What is the height requirement for primary radiation barriers?

The height requirement for primary radiation barriers is set to ensure adequate protection against direct radiation exposure in controlled areas. The standard height is typically 7 feet, which is considered sufficient to prevent not only scattered radiation but also direct rays from reaching personnel in adjacent areas.

Primary barriers are essential in locations where the radiation exposure potential is significant, such as in radiology departments. The specified height takes into account the position and possible movements of individuals, as well as the maximum level of radiation that may enter a controlled area. Thus, a height of 7 feet strikes an effective balance between safety and practicality in shielding environments where radiation is present.

Other height options, while they may offer some level of protection, do not meet the established guidelines that ensure sufficient shielding for the type and level of radiation produced in clinical settings.
