How frequently should sealed sources be leak tested?

Sealed sources are critical components in various radiation applications, and ensuring their integrity is essential for safety and regulatory compliance. Leak testing is a method used to check for the presence of radioactive material that may have escaped from the sealed source.

The correct interval for conducting leak tests is typically every six months as it strikes a balance between safety and practicality. This frequency is based on guidelines established by regulatory bodies such as the Nuclear Regulatory Commission and other organizations charged with nuclear safety. Conducting leak tests too infrequently could increase the risk of unrecognized contamination, while testing too frequently may be unnecessarily burdensome and does not significantly enhance safety.

By adhering to this six-month guideline, organizations can effectively monitor the condition of their sealed sources, ensuring any potential leaks are detected promptly, thereby protecting workers, the public, and the environment from potential radiological hazards.
