Acceptance testing for an X-ray source is performed by whom?

• A. Expert/vendor at installation
• B. Dental staff
• C. Patient
• D. Manufacturer

Answer: (A)

Acceptance testing verifies that a newly installed X-ray unit meets its specifications and safety standards before it’s used clinically. This requires specialized measurements and calibration of factors like beam alignment, timer accuracy, kVp/mA settings, exposure reproducibility, field size, and interlocks, along with proper documentation. Because of the precise testing and calibration involved, this is done by a qualified expert from the vendor at the time of installation. Dental staff handle ongoing quality assurance checks afterward, but initial acceptance testing is performed by the vendor to ensure the system is installed correctly and safe to use.
