[Gate-users] Creating a Y90 Ion source

[Nicholas Forwood]

Thanks for that, I now see a lot of Y90 ions however another stupid question my simulation does not seem to include any betas produced by decay of the Y90?

Hi Nicholas,
Try if it works.

add the following sentence under "/gate/source/Y90Source/setActivity 50.
becquerel":

/gate/source/Y90Source/gps/particle ion

Regards,
