How is low-level radiation monitored?

• A. With a Geiger counter
• B. With a badge
• C. With a smoke detector
• D. With a siren

Answer: (B)

Tracking exposure to low-level radiation for workers is done with personal dosimeter badges that accumulate dose over time. These badges are worn on the body and record the amount of radiation the wearer has received during a work period, typically updating monthly. The badge is mailed to a monitoring lab, which reads the dose and updates the person’s cumulative exposure record, helping ensure regulatory limits aren’t exceeded. A Geiger counter, while useful, measures current radiation levels in the environment in real time and is used for surveys or immediate alerts, not for recording an individual’s cumulative dose over time. Smoke detectors and sirens have no role in monitoring radiation exposure.
