Why is it essential to have barriers and shields during radiographic exposure?

The necessity of having barriers and shields during radiographic exposure is primarily to protect personnel from scattered radiation. During the process of radiography, when radiation passes through materials, it can scatter in various directions, creating a potential hazard for individuals in the vicinity. Shields are used to absorb or deflect this scattered radiation, ensuring that it does not reach personnel who might be near the radiographic area. This protective measure is critical in minimizing the risk of radiation exposure and maintaining safety standards within the working environment.

While enhancing imaging quality and reducing operational costs are important considerations in radiography, they do not address the immediate safety concerns associated with radiation exposure. The containment of radioactive waste is also an important aspect of radiation safety, but it relates more to the handling and storage of materials rather than the direct protection of personnel during radiographic procedures. Therefore, the emphasis on using barriers and shields is fundamentally about safeguarding human health from the effects of radiation.
