Radiation dosimeters should be worn:

Wearing radiation dosimeters at the collar and anterior portion of the body is the standard practice because this placement allows for accurate monitoring of exposure to radiation, particularly in areas where the radiation dose is most likely to be highest during X-ray procedures. The collar area is the part of the body generally closest to the source of radiation during many imaging processes, making it effective for detecting and recording potential exposure levels.

Additionally, by placing the dosimeter at the anterior portion of the body, it accounts for radiation scattered from the patient and equipment, which is also relevant for assessing dose. This strategic positioning helps ensure compliance with safety regulations and promotes effective monitoring of occupational exposure to radiation, ultimately safeguarding the health of the medical personnel operating the X-ray equipment.

While wearing dosimeters on the wrist, ankle, or in the pocket of the lab coat might provide some level of monitoring, these locations are not as effective for accurately capturing the radiation dose received, as they may not reflect the actual exposure experienced during imaging tasks.
