DANB Radiation Health and Safety (RHS) Complete Practice Exam 2025

Optimizing X-ray equipment settings is crucial for maintaining radiation safety in dental practice because it ensures that the minimum necessary radiation dose is used to obtain high-quality diagnostic images. Proper calibration and settings of X-ray machines help minimize patient exposure while still providing sufficient image clarity for effective diagnosis and treatment planning. This practice not only adheres to the principle of ALARA (As Low As Reasonably Achievable), which aims to reduce unnecessary exposure to radiation, but also promotes patient safety and well-being.

In contrast, increasing patient exposure would directly contradict safety protocols, as it would elevate the risk of radiation-related effects. Reducing the use of lead shields can compromise the protective measures intended to safeguard patients and staff from scatter radiation, thus increasing exposure risks. Limiting staff training would hinder their ability to operate equipment safely, further exacerbating potential risks associated with radiation exposure.
