How long must records or written logs of maintenance and/or repairs of x-ray equipment be kept?

The requirement to keep records or written logs of maintenance and/or repairs of x-ray equipment for a period of three years is grounded in regulatory and safety standards within the field of radiography. This duration ensures that there is a sufficient historical record to trace back any issues related to the equipment's performance, safety, and compliance with operational standards.

Maintaining records for three years allows operators and supervisors to review the equipment's maintenance history, identify patterns or recurring issues, and ensure that all necessary repairs and service were performed adequately. This is particularly crucial for ensuring the continued safety of both the equipment and the personnel utilizing it, as well as fulfilling any regulatory obligations that may be required by governing bodies overseeing radiographic practices. Furthermore, it aligns with best practices in quality assurance and control within the medical and industrial radiography sectors, promoting accountability and operational integrity.

The other options do not meet the regulatory expectations or ensure adequate safety oversight for x-ray equipment. Each shorter duration does not provide enough time to assess equipment reliability or safety, potentially risking compliance with safety regulations.
