[Gate-users] a question about radioactive source simulation with Gate version 6.2

[Masoud]

Dear all
I need to simulate a radioactive source with Gate version 6.2. I have used this command from manual. But radioactivity decay is not happening. Can anyone help me? Thank you.

/gate/source/NAME/GPs/particle ion /gate/source/NAME/GPs/ion 9 18 0 0 /gate/source/NAME/GPs/monoenergy 0. Kev/gate/source/NAME/setForcedUnstableFlag true # WARNING - DEBUG - New command line to debug the use of ion particle type /gate/source/F18/useDefaultHalfLife
