[Gate-users] What are the radioactive decay data files

[Francesca De Benetti]

Hello Lana,

thank you for your kind reply!
I am using the Docker image of GATE (which includes Geant4), so I guess everything is already installed there.


Best,

Francesca

> In the GATE wiki website I read that "The download of radioactive decay data files is required.”, but I don’t know where to find them and then how to include them in the simulation. Also, herehttps://github.com/OpenGATE/GateContrib/tree/06a240b36ca55b9ec00f852df65265109bba4859/dosimetry/dosimetry/protontherapy/mac <https://github.com/OpenGATE/GateContrib/tree/06a240b36ca55b9ec00f852df65265109bba4859/dosimetry/dosimetry/protontherapy/mac><https://github.com/OpenGATE/GateContrib/tree/06a240b36ca55b9ec00f852df65265109bba4859/dosimetry/dosimetry/protontherapy/mac <https://github.com/OpenGATE/GateContrib/tree/06a240b36ca55b9ec00f852df65265109bba4859/dosimetry/dosimetry/protontherapy/mac>> they don’t seem to download/include these radioactive decay data files, event though they actually use the RadioactiveDecay process.
