For optimal occupational dose monitoring, where should a dosimeter be worn?

Wearing a dosimeter at the level of the collar, outside protective apparel, is optimal for occupational dose monitoring because this placement provides the most accurate representation of the radiation exposure that an individual is receiving in relation to their head and upper body. The collar area is often where the dose can vary significantly depending on the type of radiation being monitored, as well as the position of the individual relative to the radiation source.

Positioning the dosimeter outside the protective apparel allows it to accurately measure the exposure without interference from materials that could attenuate or absorb radiation, thus providing a true reading of the radiation dose that potentially affects the individual. This kind of placement also aligns with safety standards and protocols designed to ensure precise monitoring of occupational exposure, which is crucial for maintaining safety and implementing protective measures in a radiation-dense work environment.
