X
Calculate radiography shot times for industrial radiographers using radioactive materials. Quickly determine exposure time by inputting curies, steel thickness, and source-to-film distance.
- Calculate radiography shot times
- Supports Iridium and Cobalt sources
- Input curies, thickness, and distance
- Field-tested for accuracy
- Replaces slide rule calculations

Updated for iOS10. Only Useful for Industrial Radiographers! This is an application to replace the aggravating usage of slide rules to calculate radiography shot times. It is applicable to Industrial Radiographers working with radioactive materials (not x-ray machines). It works with both Iridium and Cobalt sources. This app has been tested in the field with working radiography crews and the response has be great. Just set the number of curies, the thickness of the steel (inches), and the source to film distance (in inches). Hit the calculate button and you will have the exposure time.
