What is the purpose of engineering controls in radiation safety?

The purpose of engineering controls in radiation safety is to minimize radiation exposure through design. Engineering controls are physical modifications to a workplace that are designed to reduce or eliminate hazards, specifically by creating barriers, utilizing shielding materials, or implementing ventilation systems that can redirect or contain radiation sources. For example, the use of lead shielding in walls or barriers can effectively reduce the amount of radiation that workers are exposed to, aligning with the principles of radiation safety which emphasize reducing exposure at the source.

This proactive approach is essential as it can significantly lower the risk of adverse health effects associated with radiation exposure, compared to relying solely on personal protective equipment or administrative practices. Such controls are a fundamental element of a comprehensive radiation safety program, ensuring that exposure limits are adhered to and that safe working environments are maintained.
