In terms of radiation detection, which device is typically used for real-time monitoring?

The Geiger counter is a widely used device for real-time monitoring of radiation. It operates by detecting ionizing radiation and providing immediate feedback through audible clicks or visual indicators. This characteristic makes it especially valuable in situations requiring prompt awareness of radiation levels, such as in laboratories, medical facilities, or during radiological emergencies.

The Geiger counter's ability to give instant measurements allows professionals to assess environments continuously, helping them make informed decisions based on current radiation exposure levels. This immediacy is central to its function in monitoring radiation, distinguishing it from other devices that may not provide real-time readings.

While survey meters also serve the purpose of measuring radiation levels, they typically do so in a broader environmental context rather than specifically providing immediate personal monitoring like the Geiger counter does. Film badges and dosimeters, on the other hand, are more suited for personal monitoring over longer periods and do not give real-time feedback, making them less effective for immediate situational assessments.
