Typical fluoro skin entrance exposure rate to go through someone's hand is on the order of 1-3 millisieverts per minute. With a more advanced detector (like this one) it may be lower, but increasing the frame rate or resolution will tend to require higher dose rate. The associated risk of skin cancer is quite small. But please be aware that unnecessary X-Ray imaging of living things is against the law in most jurisdictions.
- SoftTalker 11mo agoI've wondered how much the average X-ray dosage dropped since they stopped using film and switched to detector-based imaging. Anyone know?
- scythe 11mo agoYou can compare diagnostic reference levels (DRLs) from different years for the same exam; these correspond to the 75th percentile patient dose for a particular imaging study. It can be a little annoying to find older DRLs (I just tried). NCRP 172 (published 2015) provides a direct comparison of digital to film for some examinations. For upper GI fluoroscopy without oral contrast the DRL for film is 3.9 mSv and for digital is 1.5 mSv. I think this is roughly typical.
