Texas Industrial Radiography Gamma Practice Test

Where should a film badge and dosimeter be worn for proper safety?

1. In the pants back pocket

2. On the front of the body

3. In a jacket pocket

4. Clipped to the shirt collar

The correct answer is: On the front of the body

Wearing a film badge and dosimeter on the front of the body is essential for accurate monitoring of radiation exposure. This positioning ensures that the dosimeter is exposed to the radiation field in the same way that the person is. Essentially, it reflects the actual dose received by the individual in their working environment. Positioning the badge at the front allows it to effectively measure any scattered radiation, as it is often the most significant type of exposure in an industrial radiography setting. Proper placement also minimizes the likelihood of the dosimeter being shielded by clothing or other obstructions, which could lead to inaccurate readings. In contrast, wearing a dosimeter in a back pocket, jacket pocket, or clipped to the collar could result in it being shielded from radiation. This would prevent it from measuring the correct dose and could lead to unsafe assumptions about the individual's exposure levels. Therefore, for optimal safety and accurate exposure monitoring, the front of the body is the recommended location for wearing a film badge and dosimeter.
