Where should a personal radiation monitor typically be worn?

• A. At ankle level, facing forward
• B. At collar level, facing forward
• C. At hip level, facing backward
• D. On the wrist, inward facing

Answer: (B)

A personal radiation monitor should typically be worn at collar level, facing forward, because this placement ensures that the device accurately measures the radiation exposure received by the individual's head and upper body, where most occupational radiation exposure occurs in healthcare settings such as radiology or nuclear medicine. The collar position allows for better detection of scattered radiation that may be prevalent during imaging procedures.

This placement also minimizes interference from other sources of radiation that might be encountered closer to the waist or limbs, where exposure levels may not effectively represent the radiation dose that could impact critical organs like the thyroid or bone marrow. By wearing the monitor at collar level, professionals can obtain a more reliable assessment of their personal radiation dose during their work, enabling them to manage their exposure effectively.
