How long must records of maintenance and repairs of x-ray equipment be kept?

• A. 1 year
• B. 30 years
• C. 3 years
• D. 1 month

Answer: (C)

Maintenance and repair records are part of the ongoing quality assurance of x-ray equipment. Keeping these logs for a set period allows you to verify that the machine has been properly serviced, identify recurring problems, and demonstrate compliance during inspections. Three years provides a practical window to observe maintenance trends, track calibration and service cycles, and have documentation available for audits or incident reviews. Shorter timeframes risk losing important service history, while much longer periods aren’t typically required for routine maintenance records. So, three years is the appropriate retention period.
