What is the primary purpose of a dosimeter in radiation safety?

• A. Monitor accumulated radiation dose
• B. Measure chemical exposure
• C. Detect noise levels
• D. Track work hours

Answer: (C)

A dosimeter is used to track the amount of radiation a person has actually received over time. It records the accumulated dose, providing a record that helps ensure a worker’s exposure stays within safety and regulatory limits and signals when protective actions are needed. It isn’t meant to measure chemical exposures, detect noise levels, or track work hours—those require different tools or systems (air/chemical sampling for chemicals, a sound level meter for noise, and timekeeping for hours worked).
