A device that contains a film packet 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 ionizing radiation a person has been exposed to is done with a dosimeter worn on the body. A film packet inside this device records exposure by the film darkening in proportion to the dose, producing a readable record of cumulative exposure—this is why it’s called a radiation monitoring badge. It’s specifically designed to detect and measure personnel exposure and is processed to determine the dose received, helping keep workers within safety limits. The other terms aren’t dosimeters: a radiograph is an X-ray image, radiology is the imaging field, and penumbra is a partial shadow around an edge in imaging.
