Film badges are primarily used in the field of radiology and other areas involving radiation exposure to monitor the occupational exposure of personnel working in these environments. They are effective tools for tracking the amount of radiation that a worker is exposed to over time, thus helping to ensure that exposure remains within safe limits.

Film badges also serve the purpose of documenting cumulative exposure. This is important for maintaining records regarding the total radiation dose received by an individual over their career, which is essential for ensuring long-term safety and adherence to regulatory guidelines.

However, film badges are not designed to evaluate the exposure that a patient receives during radiological procedures. The assessment of patient exposure is carried out using different dosimetry techniques and devices that specifically measure the radiation dose delivered to the patient from various imaging modalities. Film badges are focused on the monitoring of personnel rather than patient doses, which is why the assertion regarding patient exposure evaluation does not align with the intended use of film badges.

Additionally, film badges do not provide patient identification. Patient identification is typically managed through other systems and protocols, ensuring that each patient's records are accurately tracked and identified, separate from the occupational monitoring of radiology staff.
