Question How to define a source with multiple radionuclides with different activities?

Good Day,

I was wondeirng if someone could help me figure out how to define a volume source that contains multiple radionuclides with various activities? Let's say I have a source which contains Co-60 and Pb-210, and Co-60 has activity A1 and Pb210 has an activity A2, both in Becquerels (Bq). Also the source is a cylindrical volume source. If I was only concerned with one of these radionuclides my macro file would contain the following /gps/ commands:

# For Co-60
/gps/particle ion
/gps/ion 27 60 0 0
/gps/pos/type Volume
/gps/pos/shape Cylinder
/gps/pos/centre 0 0 0 mm
/gos/pos/radius 40 mm
/gps/pos/halfz 2 mm
/gps/ang/type iso
/run/beamOn 10000

My issue is I'm a) not sure how to specifiy the activity of my source, and b) how to include multiple radionuclides with differing activityies, going back to the Co/Pb example with A1 and A2?

If anyone can give me some sort of afdvice I'd greatly appreciate it!
