Hello Gate Users,

I am confused with the source activity when i read the manual and the 
SPECTbench.mac file.

In the SPECTbench.mac, the activity of the source is 30000 Bq, is it the 
total activity of the volume of

/gate/source/SourceConfinement/gps/radius 2. cm
/gate/source/SourceConfinement/gps/halfz 14.5 cm

or of the volume of

/gate/movsource/geometry/setRmax 2.  cm
/gate/movsource/geometry/setRmin 0. cm
/gate/movsource/geometry/setHeight 5. cm

If it is the activity of the first one, what if the moving source out of 
the range that volume? Thanks!

Qianmei
