Exposure Time Calculation

This app is used to calculate exposure time for Gama Ray (Ir-192) and X-Ray (Crawler, CME, and Zhong Yi) when conduct Radiography Testing in Non-Destructive Testing.

The calculation depends on many factors:

Material

Exposure thickness

Type of films

Density

Source to film distance

Activity (in case of Gama Ray) or kV and mA (in case of X-Ray)

This app is recommended to use when manual film processing.
