ASNT Industrial Radiography Radiation Safety Practice Test

After an exposure, what is the advised action regarding the tube head to ensure safety?

1. Approach it immediately

2. Wait at least 2 minutes

3. Wait until the alarm goes off

4. Perform a visual inspection before approaching

The correct answer is: Approach it immediately

The recommended action regarding the tube head after an exposure is to perform a visual inspection before approaching it. This practice ensures safety by allowing the radiographer to assess the immediate area for any potential hazards or visual abnormalities. Observing the tube head visually from a safe distance helps to confirm that it is in a safe condition, that there are no visible leaks, and that the equipment is functioning properly before one gets closer. This precaution is crucial in reducing exposure to radiation, as approaching the tube head without proper evaluation could increase the risk of radiation dose to personnel. Also, waiting for an alarm to indicate safe levels might not always reflect the immediate safety unless the system is designed to do so accurately. Therefore, understanding and implementing a thorough visual inspection as a standard practice enhances radiation safety in industrial radiography.
