How often must leak tests on cobalt-60 be performed?

Leak tests on cobalt-60 must be performed every six months. This requirement is established by regulatory bodies to ensure safety and compliance in the handling of radioactive materials. Cobalt-60, being a commonly used radioactive isotope in medical and industrial applications, poses potential hazards if leaks occur. Regular testing every six months helps to detect any possible leakage of radioactive material, thereby minimizing the risk of exposure to radiation for personnel and the environment.

This interval balances the need for safety with practical considerations in monitoring and managing the use of cobalt-60, ensuring that any concerns can be addressed promptly while maintaining operational efficiencies. Performing these tests more frequently than necessary could impose undue operational burdens without significantly enhancing safety, while longer intervals may increase risk.
