Dear Amor,
I am not sure if I can answer your question without the input data as example.
However, I can give you some hints, but feel free to send your input data if you need further details.
Regarding your first questions, the differences between your experimental data and FLUKA’s values might come from the score normalization per primary or the units of your score:
DOSE score is given in GeV/g per primary particle.
In your case, the primary particle are the nuclear transformations, if you used HI-PROP card to simulate your 60Co source.
So, your DOSE score corresponds to deposited energy in GeV/g per disintegration.
You have to normalize this score to the activity of your 60Co source and to convert the GeV/g in J/kg.
For your second question, it seems in your score you just selected from which volume to score but not the ending volume.
The right way to score in a region (TM34060 in your case) is your first example.
Best regards,
Thomas Frosio

Subject: [fluka-discuss]: Dose in a region
Dear fluka/flair experts,
I'm a beginning user and I am trying to measure the total dose, energy and fluence into a metallic box when I use a 60Co source. My geometry is compounding to:
- The real lab dimensions (porland and plaster)
- A simplification of gamma radiator (lead, heavymetal, W... other materials)
- Inside the radiator a recreation of real Co source.
- The lead-aluminium box
- Inside the box: Silicon cylinder with the same size of the real sensor that we have in our box.
I'm trying to obtain the Dose in the sensor region. When I used this:
USRBIN 12. DOSE -31. TM34060 TM34060
USRBIN TM34060 &
I obtain a value but it not similiar with the experimental data. Experimental data is arround 600 rad and with the fluka simulation we have in the order to mrad.
And if I use this:
USRBIN 12. DOSE -31.
USRBIN TM34060 &
I obtain 0.0 E+0
Could you help me to find a solution?
Thank you.
Best regards,
Amor Romero
