What is the primary purpose of dosimetry for monitoring external exposure?

• A. To monitor and record occupational exposure
• B. To measure shielding thickness
• C. To calibrate instruments
• D. To detect contamination on surfaces

Answer: (A)

Tracking how much radiation a worker is exposed to from external sources is what dosimetry is all about. The dosimeter records the dose the person receives during their work, providing a numerical history of occupational exposure. This information lets safety programs ensure doses stay within regulatory limits and that protections are effective, using the data to keep workers healthy and to satisfy reporting requirements. The other tasks aren’t about monitoring a person’s exposure: shielding thickness is part of barrier design to reduce exposure, calibrating instruments is about ensuring measurement devices read accurately, and detecting contamination on surfaces concerns surface contamination checks rather than the external dose a worker receives.
