How should a personal dosimeter be properly used in a radiography setting?

In a radiography setting, a personal dosimeter is crucial for monitoring radiation exposure to ensure personnel safety and compliance with regulatory standards. It should be worn on the outside of the lead apron at collar level because this position allows for accurate measurement of the radiation dose received by the radiographer. The collar area is typically the most exposed part of the body when radiation is being administered, so placing the dosimeter here provides a true reflection of the radiation exposure that the worker is experiencing.

Wearing the dosimeter under the lead apron or at waist level, as suggested in some of the other options, would lead to inaccurate readings, as the lead apron is designed to shield the body from radiation. By placing it in a pocket or keeping it in a control room, the dosimeter would not be effectively monitoring the true exposure level, exposing the individual to potential risks without proper tracking of radiation dose. Therefore, the correct method of wearing the dosimeter ensures that effective monitoring and protection protocols are followed in the radiologic environment.
