Personal dosimetry devices are designed to evaluate which of the following?

• A. Non-Ionizing Radiation Dose
• B. Radiation Output Of X-Ray Machines
• C. Occupational Radiation Dose
• D. Radioactive Contamination

Answer: (C)

Personal dosimetry devices are designed to measure the amount of radiation a worker is exposed to in the workplace, i.e., occupational radiation dose. They are worn by personnel to accumulate a record of the radiation dose received over a monitoring period, which helps ensure exposures stay within regulatory limits and supports ALARA practices. This type of dosimeter captures the wearer’s actual exposure, not the machine’s output or surface contamination.

They aren’t meant to assess non-ionizing radiation, which is measured with different equipment, nor do they directly measure the X-ray machine’s output or detect radioactive contamination—those require separate instruments or methods (output tests and contamination monitors, respectively).
