What Gamma Calculator Pro Is Used For

Gamma Calculator Pro appears to be a productivity app for calculating radiation exposure times in a radiography workflow. Based on the metadata, it is designed for use with Iridium-192, Selenium-75, and Cobalt-60 sources, and it helps users estimate exposure time by entering values such as thickness, activity in curies, and source-film distance.

The Pro version also includes a barricade calculation for 2mR and 100Mr distance, which suggests it may be used when planning or checking distances around exposure setups. Since it is a phone app and mentions different densities and film types, it seems intended for on-site calculations where quick reference is useful. The listed vibration permission may indicate simple alerts or feedback, while the license check permission is typical of paid app validation rather than a user-facing feature.
