The safelight should be located a minimum of how many feet from the counter?

The correct answer is based on guidelines that establish safe practices in darkroom environments where dental radiography is conducted. A minimum distance of 4 feet for the safelight from the counter is recommended to ensure that light leaks do not affect the film's sensitivity and ultimately influence the quality of the radiographic images.

This distance helps to prevent fogging of the radiographic film, which can occur if the safelight is positioned too close to the workspace. The proper placement of the safelight is crucial to maintain the integrity of the films being processed, allowing for proper exposure and development without unintended interference from light. Keeping the safelight at this recommended distance contributes to producing high-quality radiographs, which is essential for accurate diagnosis and patient care.
