What is generally the best strategy to minimize exposure to scattered radiation?

Using lead shielding is indeed considered the best strategy for minimizing exposure to scattered radiation. Lead is an effective barrier material due to its high density and atomic number, which absorb and attenuate radiation. When properly positioned, lead shielding can significantly reduce the intensity of scattered radiation that reaches personnel who may be present during radiographic procedures.

In radiographic environments, scattered radiation can come from various interactions that occur with the tissues or items being imaged. By implementing lead shielding, operators can protect themselves and others from unnecessary radiation exposure and ensure compliance with safety regulations regarding radiation protection.

While increasing the source activity or reducing distance from the source may seem like effective strategies, they can actually increase the overall exposure to personnel. Increasing exposure time would obviously lead to higher radiation doses as well. Therefore, using lead shielding stands out as the optimal method for reducing scattered radiation exposure effectively and safely.
