Who is required to wear a personnel dosimeter?

The requirement to wear a personnel dosimeter is based on the potential for individuals to be exposed to ionizing radiation in the workplace. The appropriate threshold for this requirement is an estimated annual occupational dose of 5 millisieverts (mSv). This level is significant because it aligns with safety regulations and guidelines designed to protect workers from excessive radiation exposure.

Wearing a dosimeter allows for the continuous monitoring of radiation exposure, ensuring that individuals working with or around ionizing radiation can track their exposure levels throughout the year. It serves as a critical tool for both personal safety and regulatory compliance.

Compliance with these safety measures becomes fundamental as it reflects an understanding of occupational health standards. Workers who may reach or exceed the 5 mSv threshold need to have their exposure assessed accurately to minimize health risks associated with radiation and to promote safe working conditions.

The other choices inaccurately describe the thresholds or conditions related to dosimeter usage. Their parameters either underestimate or do not align with established safety protocols for radiation exposure monitoring.
