Where should a personnel dosimeter be placed on the body of a limited operator?

The appropriate placement of a personnel dosimeter is on the region of the collar outside the lead apron. This position is recommended because it provides an accurate measure of radiation exposure to the individual’s head and neck, which are areas not shielded by the lead apron. The collar area is typically the most likely place for scatter radiation to be present, allowing for the best assessment of potential exposure.

Placing the dosimeter in this location helps ensure compliance with safety regulations and allows for effective monitoring of any potential radiation exposure. By wearing the dosimeter outside the lead apron, it remains unobstructed and can accurately record doses that could be received during radiographic procedures. This is critical for maintaining adherence to occupational dose limits and ensuring the safety of personnel working with radiation.

Other placements, such as on the wrist inside a lead glove or on the ankle outside the lead apron, may not provide an accurate representation of overall radiation exposure. Additionally, positioning the dosimeter on the back of the body under the lead apron restricts its ability to measure exposure effectively due to the shielding effect of the apron.
