At what level should a dosimeter for occupational dose monitoring be worn?

The dosimeter for occupational dose monitoring should be worn at the collar, outside of protective apparel, to accurately measure the radiation exposure to the individual. Positioning the dosimeter in this manner ensures that it is able to detect radiation in the area of most likely exposure, while also avoiding interference from protective gear that could shield the dosimeter from radiation.

Wearing the dosimeter at the collar allows it to be in a location where it is more exposed to radiation fields, reflecting the dose received by the worker in a manner that is relevant to their risk level. The collar placement also maintains ease of access for regular monitoring, ensuring that the device can be checked or replaced as needed without cumbersome adjustments.

In contrast, wearing a dosimeter in other suggested locations, such as at the waist or on the wrist, can lead to inaccurate readings as these areas may not represent the primary exposure point, especially in certain occupational settings. Similarly, placing it on the forehead or under protective apparel would likely obstruct its ability to effectively measure radiation doses accurately, thus diminishing the effectiveness of monitoring.
