Radiology Practice Test

True or false, does a film badge evaluate exposure the patient receives?

1. True

2. False

3. Not specified

4. None of the above

The correct answer is: False

A film badge is designed primarily to measure the radiation exposure that a personnel receives while working in environments where radiation is present, such as in radiology or nuclear medicine settings. It does not evaluate the exposure that a patient receives during a radiological procedure. The film badge contains materials that change color in response to radiation exposure, allowing for the assessment of the dose absorbed by the worker over time. In contrast, the assessment of patient exposure is typically done using different dosimetry techniques, such as dosimeters installed on imaging equipment or calculations made based on the technique and settings used during the examination. Therefore, the statement that a film badge evaluates the exposure the patient receives is false.
