Where should the control badge be maintained?

• A. In the lead apron pocket
• B. In a radiation-free area
• C. In the dosimeter storage cabinet
• D. On the radiation monitor

Answer: (B)

The control badge, which is used to measure background radiation and ensure accurate monitoring of personal dosimeters, should be maintained in a radiation-free area. This location is crucial because it serves as a baseline measurement against which the exposure recorded on personal badges can be compared. Keeping the control badge away from any radiation sources helps to prevent it from registering any radiation exposure that does not represent the actual working conditions of the radiographer or personnel using radiation.

Maintaining it in a designated, controlled environment minimizes the risk of extraneous exposures, supporting the integrity of the monitoring process and ensuring that any readings are as accurate as possible. Thus, this practice is vital for both compliance with safety standards and for providing an accurate assessment of a worker's exposure to radiation over time.
