Fluoro Room Shielding
Spot Film Cassettes
Uses conventional radiographic cassettes.
Bypasses image intensifier for direct exposure.
Uses mA > 100 X that of photofluoro camera.
F-num =50 mm / 20 mm = F 2.5
The smaller the f-number - the larger the aperture opening.
The larger the f-number - the smaller the aperture opening.
Spot Film and Cine Cameras
Exception would be in R/F room where all walls would be a primary barrier.
