ASNT Industrial Radiography Radiation Safety Practice Test

How often must film badges be replaced?

1. Every week

2. Every two weeks

3. At intervals not to exceed one month

4. Every three months

The correct answer is: At intervals not to exceed one month

The correct answer regarding the frequency of replacing film badges is that they must be changed at intervals not to exceed one month. This guideline is based on maintaining optimal monitoring of radiation exposure. Film badges are used to measure the accumulated dose of ionizing radiation over time, and their efficacy can be influenced by factors such as exposure levels and environmental conditions. By replacing the film badge every month, facilities ensure that they are obtaining accurate readings of radiation exposure for individuals working in areas where radiation is present. This regular replacement also allows for timely assessment and action if exposure levels approach or exceed safety limits, thereby helping to protect workers from potential overexposure to radiation. In accordance with safety protocols, regular monitoring is crucial for maintaining compliance with health and safety regulations in radiography practices.
