Where should a dosimetry badge be worn when working near radiation sources?

A dosimetry badge is designed to measure the exposure a person receives from ionizing radiation. It should be worn on the front of the body between the neck and the waist primarily because this positioning ensures that the badge accurately records any radiation dose received by the individual's torso, which is typically the area of highest exposure when working near radiation sources.

By placing the badge in this location, it also accounts for radiation exposure that may come from various directions, as most radiation monitoring aligns with the principle that the torso is a critical area for assessing effective dose. This positioning maximizes the accuracy and relevance of the dosimetry readings, making it easier to manage and evaluate occupational exposure to radiation effectively.

In contrast, wearing the badge on other parts of the body, such as the arm, leg, or back, may not provide accurate readings due to their distance from the central area where radiation exposure is usually concentrated, potentially leading to underreporting or misinterpretation of an individual’s radiation dose.
