CAMRT Radiography Practice Exam

In terms of patient safety, why is it necessary to use a primary X-ray barrier?

1. To reduce the cost of imaging

2. To block unwanted radiation from affecting the patient and staff

3. To maintain equipment integrity

4. To improve image quality

The correct answer is: To block unwanted radiation from affecting the patient and staff

The necessity of using a primary X-ray barrier is primarily linked to the protection of both patients and staff from unnecessary radiation exposure. Primary X-ray barriers are designed to absorb the primary radiation beam, which minimizes the risk of scattering and reduces the dose of radiation that reaches individuals who are not the intended focus of the imaging procedure. By serving as a protective shield, these barriers help ensure that patients and healthcare workers are safeguarded against the potential adverse effects associated with radiation exposure, such as increased cancer risk and other radiation-related health concerns. While other choices might touch on relevant topics, they do not directly address the core purpose of X-ray barriers in the context of radiation safety. For instance, cost reduction is not a primary factor influencing the need for barriers, maintaining equipment integrity pertains to equipment maintenance rather than safety concerns, and while image quality is important, it is not the primary function of barriers. The main objective remains focused on creating a safer environment for all individuals involved in or around radiographic procedures.
