Added tube filtration should be adjusted by the radiographer:

• A. To 'harden' the x-ray beam
• B. To remove the soft rays from the x-ray beam
• C. To exercise radiation protection
• D. Never

Answer: (D)

Beam filtration changes the energy distribution of the X-ray beam. Added filtration removes low-energy photons, hardening the beam, which can lower patient skin dose but may reduce image contrast. In routine practice, how much filtration is present is set by equipment design and approved protocols, and any adjustment should be handled only by authorized personnel under QA guidelines, not by the radiographer during a procedure. So added tube filtration should never be adjusted by the radiographer.
