A device used to detect and measure radiation exposure of personnel is called what?

• A. Radiation Monitoring Badge
• B. Radiograph
• C. Radiology
• D. Penumbra

Answer: (A)

Measuring how much radiation a person has been exposed to is essential for safety around ionizing radiation. The device designed for this purpose is a radiation monitoring badge, a type of dosimeter worn on clothing that records the cumulative dose over a work period. This readout helps ensure exposure stays within safety limits. The other terms refer to different things: a radiograph is an X-ray image, radiology is the medical field that uses imaging, and penumbra is the partial shadow at the edge of an image. So the badge is the device specifically used to monitor exposure.
