Which method(s) could be used to reduce radiation dosage for conventional film radiographs?

• A. Use speed D film, increase KvP
• B. Use E or F speed film, use a round collimator
• C. Use E-speed film, increase KvP
• D. Decrease exposure time, use rectangular collimation

Answer: (C)

To reduce radiation dosage for conventional film radiographs, it's important to consider both the type of film used and the exposure settings. The chosen answer emphasizes the use of E-speed film, which is faster than D-speed, allowing for the same diagnostic quality at a lower radiation dose. E-speed film requires less exposure time because it is more sensitive to radiation, thus minimizing the overall dose administered to the patient. Additionally, increasing the kilovoltage peak (KvP) can enhance the quality of the image, making it possible to achieve acceptable diagnostic results with a lower radiation dose. A higher KvP increases the energy of the x-rays, allowing them to penetrate tissues more effectively while also reducing the overall quantity of radiation needed. In summary, using E-speed film combined with increasing KvP is a prudent strategy for minimizing radiation exposure during conventional film radiography while still obtaining high-quality images.
