Hi Izfneu,
If you associate an irradiation/cooling profile to your RESNUCL card, then the code will compute activity Bq/cm^3. If you don't and you use usrsuw to merge results, then you get nuc/cm^3, which is the production rate of given NUClei per unit volume.
See slide 21 of:
https://indico.cern.ch/event/334606/contribution/39/material/slides/0.pdf
Concerning your question about the relationship between the density of residual nuclei production nuc/cm^3 versus their specific induced activity Bq/cm^3, as you know, in equilibrium they are identical when other decay chains INTO those nuclei are negligible.

Subject: RE: how to calculate the density of the residual nuclei
Hi Mario and all,
Thanks for your reply, but i'm still confused about the values in *_.sum.lis and *_.tab.lis files.
The averaged values with statistical uncertainty for all radionuclides of *.sum.lis and *.tab.lis files are in unit of Bq/cm3.
In my opinion those are the values of induced activity for each radionuclides.
Does the density of the residual nuclei eaqual to the values of induced activity, I'm confused about the conception. Please give me some advice. Thanks in advance.

Hi Izfneu,
Yes, the instructions that Joachim have given you are adequate to compute such type of values. The normalization to the volume can be performed with FLUKA if you previously define the volume of the target (in cm^3) in WHAT(6) of RESNUCL card, otherwise, do it offline later.

Subject: how to calculate the density of the residual nuclei
Thanks, here is another question:
how to calculate the density of the residual nuclei for electrons like the data table in the attatchment, can fluka do that ?
I have attatch the data table that I extract from a paper in the attatchment.
Thanks in advanced.
