[2025-10-01T19:06:32.656326] [PI reasoning] **Evaluating radiographic exposure methods**

I need to identify the best method for reducing patient somatic exposure in radiography. In dental X-ray, using faster film can lower exposure significantly—switching from D-speed to E-speed might reduce it by 30-50%. While lead aprons protect organs, they don’t reduce exposure to the targeted area. Added filtration helps but has limited effects. Open-ended, shielded cones (collimation) are effective, especially rectangular collimation, which can decrease tissue exposure by about 60%.
