Hi Nkanyiso,
Just to be sure, you want to use a radioactive isotope as a volumic source ? Not a particle beam, is this correct ?
If this is the case, in the example below I am defining a cylindrical shape Tl-204 source (you can overlay the source to a material in the geometry if the radionuclides are within a matrix material):
BEAM 1.0ISOTOPE
BEAMPOS 0.0 0.15 0.0 0.24 0.0 CYLI-VOL
BEAMPOS 0.0 0.0 -0.125
HI-PROPE 81. 204.
*
Activate the decay in semi-analogue mode
RADDECAY 2.0
*
Use -1.0 for the card below as you are in semi-analogue mode
DCYSCORE -1.0 0. 0. DR-All DR-All USRBIN
*
*
USRBIN 10.0 DOSE-EQ -45.0 80.0 0.4 80.0DR-All
USRBIN -80.0 -0.4 -80.0 160.0 1.0 160.0&
*
Your results will be normalized per decay of the radionuclides defined with the HI-PROPE card. If you have a xxx Bq source then you have to normalize the score quantities to your source activity
Hoping this help
Joachim

Subject: Definition of Radioactive Target
Dear FLUKA users,
I have a problem with defining the radioactive target, where I will just measure the activity of the target without hitting it with a beam.
Any idea will be appreciated.
Regards
N.R Mantengu
