ASNT Industrial Radiography Radiation Safety Practice Test

When a source or exposure device shows a wipe test result exceeding the threshold of 0.005 μCi (185 Bq), it indicates that there is a potentially significant contamination that could pose a safety risk. In such cases, it is essential for the licensee to ensure the safety of the environment and personnel by immediately removing the device from service. This prompt action helps to prevent any further exposure and allows for a thorough investigation and cleaning or safe disposal of the source. Removing the device from service is a crucial first step to control the situation. After removal, further actions, such as notifying the regulatory body, conducting follow-up testing, or continuous monitoring, may also be required to ensure compliance with safety standards. However, the immediate response is to eliminate the risk by taking the device out of operation.
