For how long must records of maintenance and/or repairs of x-ray equipment be kept?

The requirement to keep records of maintenance and repairs of x-ray equipment for a period of three years aligns with regulatory standards set by agencies such as the Health and Safety Executive (HSE) and the American National Standards Institute (ANSI). This duration ensures that there is a comprehensive history available for each piece of equipment, which can be crucial for tracking performance issues, ensuring compliance during audits, and maintaining overall safety standards.

Keeping these records for three years also supports the need for proper documentation in case of investigations related to incidents or malfunctions involving the equipment. This timeframe is adequate for reflecting on the ongoing maintenance practices while preventing organizations from being burdened with excessively lengthy retention periods that could complicate record-keeping processes. The other durations do not meet these regulatory expectations, which is why they are not suitable choices.
