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.
