Where should radiographers clip their radiation monitors when wearing an apron for fluoroscopy?

• A. At the collar, beneath the lead apron.
• B. At the waist, beneath the lead apron.
• C. At the collar, outside of the lead apron.
• D. At the waist, outside of the lead apron.

Answer: (C)

The important idea here is to place the dosimeter where it can measure exposure to tissues that are not protected by PPE. A lead apron shields the torso, but areas like the neck and head are exposed to scatter and leakage during fluoroscopy. Putting the radiation monitor at the collar outside the apron ensures you capture the actual dose reaching those unshielded areas, giving an accurate indication of potential risk to sensitive tissues such as the thyroid and eyes. If the dosimeter were worn beneath the apron, it would be shielded and would underestimate the exposure to unprotected regions. Wearing it at the collar outside the apron provides the correct monitoring location for this scenario.
