CAMRT Radiography Practice Exam

If a radiography procedure is extended beyond which standard time does the fluoroscopy timer activate?

1. 3 minutes

2. 5 minutes

3. 7 minutes

4. 10 minutes

The correct answer is: 5 minutes

The fluoroscopy timer is designed to enhance patient safety by preventing excessive radiation exposure during procedures that utilize fluoroscopy. In many jurisdictions and according to various safety standards, the timer is programmed to activate an alert when the cumulative fluoroscopy time reaches or exceeds 5 minutes. This alert serves as a reminder for operators and healthcare professionals to reassess the need for continued fluoroscopic imaging and to consider the potential risks associated with prolonged exposure. This is particularly important in radiographic procedures that may involve complex imaging and longer durations, as the accumulation of dose can increase the risk of radiation-induced injuries. The standard time of 5 minutes is widely recognized and serves as a benchmark that aligns with safety guidelines from organizations focused on radiation safety and patient care. Understanding this interval is essential for radiologic technologists and healthcare providers to ensure they are monitoring radiation exposure effectively during procedures.
