What is the ACR standard for room illuminance?

The ACR (American College of Radiology) standard for room illuminance is set at less than 50 lux. This value is established to create an environment that minimizes glare and reflections on the display monitors and other surfaces, which is essential during fluoroscopic procedures. Excessive room lighting can lead to discomfort and visual strain for healthcare workers, as well as impact the quality of the imaging by creating obstructions in visual clarity.

The standard is designed with patient care and safety in mind, ensuring that healthcare professionals can maintain focus on the procedure without distractions from overly bright lighting conditions. Therefore, the correct answer aligns with the guidelines set forth by the ACR, promoting an optimal working environment for both staff and patients during examinations that involve fluoroscopy.
