How often should emergency beam off switches be tested?

Emergency beam off switches are critical safety devices used in radiation therapy to immediately terminate the radiation beam in case of an emergency. The frequency of testing these switches is crucial to ensure their reliability and functionality when needed.

Daily testing is required because it ensures that the switches are always operational, given the potential risks associated with radiation therapy. Regular daily checks help identify any malfunction before they become serious issues, improving the overall safety of the treatment environment. Consistency in testing allows for quick corrective actions if any problems are detected, thus ensuring patient safety and compliance with regulatory standards for radiation therapy equipment.

In contrast, other options suggest longer intervals between tests, which could lead to undetected failures and increased risks during treatment sessions.
