California ASRT S&O Practice Exam 2025 – Comprehensive Test Preparation

Increasing patient exposure in radiographic practices typically indicates a higher risk of radiation effects. In radiology, exposure refers to the amount of ionizing radiation the patient receives during a procedure. The principle of radiation protection stresses the importance of keeping exposure as low as reasonably achievable (ALARA). Elevated exposure levels can lead to an increased probability of stochastic effects, such as radiation-induced cancer or other long-term health issues, as the cumulative effect of radiation on biological tissues can be harmful.

While improved image quality and increased diagnostic information can be aided by optimizing exposure parameters, they should not come at the cost of patient safety. Higher exposure does not guarantee better equipment performance; it rather raises concerns related to the safety and well-being of patients undergoing radiologic examinations. Thus, an understanding of radiation exposure is critical in balancing the need for diagnostic information against the potential risks associated with higher radiation doses.
