Which group of individuals is required to wear personal dosimetry devices?

The correct choice highlights that anyone exposed to ionizing radiation as part of their occupation is required to wear personal dosimetry devices. These devices are critical tools used to monitor and measure the amount of radiation exposure an individual receives over time. This requirement is particularly crucial in maintaining health and safety standards in environments where radiation exposure could occur, such as hospitals, nuclear power plants, and research laboratories.

Personal dosimetry is essential not only for protection but also for compliance with regulatory standards aimed at minimizing radiation-related health risks. This includes workers in medical fields like radiology, oncology, and nuclear medicine, as well as individuals involved in research or industrial activities that involve radiation sources.

In contrast, individuals in non-radiation roles or those not exposed to radiation do not require such devices, as their work does not involve the risks associated with ionizing radiation exposure. This broader requirement reflects both safety measures and regulatory compliance across various occupations dealing with potential radiation hazards.
