ASNT Industrial Radiography Radiation Safety Practice Test

What must be done if a film badge shows off-scale readings?

1. It must be discarded immediately

2. It must be processed within 24 hours

3. It must be re-calibrated

4. It must be sent for further testing

The correct answer is: It must be processed within 24 hours

When a film badge shows off-scale readings, it indicates that the radiation exposure has exceeded the measurable limit of the badge, suggesting potentially high levels of exposure that need to be appropriately managed. Processing the film badge within a specific time frame, such as 24 hours, is crucial to ensure that the exposure is accurately assessed and documented. Delaying the processing could lead to degradation of the film or loss of critical data regarding the individual's radiation exposure. Timely processing allows for immediate review and necessary action to be taken, such as medical assessment or additional monitoring to protect worker safety. Understanding the implications of an off-scale reading ensures that effective radiation safety protocols are upheld, giving employers and health physicists vital information to do risk assessments and implement corrective measures if necessary.
