Texas Industrial Radiography Gamma Practice Test

When exposed to radiation, what is the primary goal of wearing a film badge?

1. To calculate hourly exposure

2. To measure cumulative exposure

3. To limit personal exposure

4. To provide medical diagnosis

The correct answer is: To measure cumulative exposure

Wearing a film badge is primarily aimed at measuring cumulative exposure to radiation. Film badges contain special film that is sensitive to ionizing radiation, which allows for the monitoring of an individual's exposure over a period of time. When the film is processed, it indicates the level of radiation exposure the wearer has experienced, which can be used to assess whether exposure is within safe limits specified by regulations. This cumulative data is crucial for evaluating long-term exposure risks and ensuring that individuals working in environments where radiation is present are not exposed to levels that could lead to health issues. It plays a vital role in maintaining safety standards and implementing necessary precautions. The other options, while related to the topic of radiation safety, do not accurately describe the primary function of the film badge. Calculating hourly exposure is not a direct functionality of the film badge as it measures exposure over longer periods rather than on an hourly basis. Limiting personal exposure is more about safety procedures and practices than the function of the film badge itself. Providing a medical diagnosis is unrelated to the purpose of a film badge in monitoring radiation exposure.
