What is the purpose of dosimetry in radiation work safety?

• A. To measure temperature
• B. To schedule breaks
• C. To monitor athletic performance
• D. To measure and record the radiation dose received by workers

Answer: (D)

Dosimetry provides a quantitative way to track how much radiation a worker has been exposed to. By measuring and recording the dose, we can ensure exposures stay within safety limits and are as low as reasonably achievable. Personal dosimeters—like film badges, thermoluminescent dosimeters, or electronic dosimeters—are worn to capture the amount of radiation received over a period and are read out after shifts to document the exposure history. This data guides safety decisions, such as when shielding should be added, tasks reorganized, or work practices adjusted to reduce dose, and it creates an official record needed for regulatory compliance and medical assessment. Other options address unrelated topics and do not quantify or track radiation exposure.
