Explain the purpose and typical features of a dosimeter badge system and how results are read.

• A. Personal dosimeters measure instantaneous dose rates and are read daily.
• B. Dosimeters are safety devices used to shield workers from radiation.
• C. Personal dosimeters measure cumulative dose; worn on body; read by a processor at the end of a monitoring period; used to determine exposure dose for regulatory compliance.
• D. A dosimeter is the same as a Geiger counter.

Answer: (C)

Dosimeter badge systems are designed to quantify a worker's cumulative radiation exposure over a defined monitoring period. They are worn on the body (typically at chest or collar level) to approximate whole‑body exposure and are not used to shield the worker. The badge captures the total dose accumulated during the monitoring period, and at the end of that period it is sent to a dosimetry processor or readout system. The processor reads the badge, converts the measured signal into a dose value using the appropriate detection method (film, thermoluminescent, or optically stimulated luminescent techniques), and records this dose on the individual’s dose history. This resulting dose is then used to determine whether regulatory exposure limits have been met for the worker and to guide any necessary changes in shielding, work practices, or assignment to reduce future exposure.
