About RBApp: Equivalent Dose-Fractionation

What is RBApp?

RBApp stands for RadioBiology Application and is a web application. This web application allows quick access to radiobiological calculations, right on your device or computer. Keep in mind, however, that the results of calculations are for educational purposes only, and should not be used for clinical decision making.


This program allows conversion from any arbitrary dose-fractionation (with total dose D1 in d1 per fraction) to another dose-fractionation with a user-defined d2 per fraction. To use this program, input numbers into all of the fields: D1, d1, d2, and α/β. The program will output values (total dose for alternative dose-fractionation, D2) at the bottom of the page.
