Gamma Calculator Pro

Gamma Calculator Pro

By Gerrit kleyn Winkel

Gamma Calculator Pro is a specialized industrial tool designed for radiographers to calculate exposure times for Iridium-192, Selenium-75, and Cobalt-60 sources. It replaces traditional manual calculations and plastic slide rules by automating complex variables like material density, source-film distance, and decay. The app supports a wide range of materials and provides essential safety and geometric configuration tools for field operations.
