Hi
It is quite straightforward, have a look at the presentation given in the last FLUKA course on activation calculations. You define your irradiation profile, cooling time of interest, score with RESNUCLE the produced radionuclides in the beam dump at cooling time of interest (DCYTIMES and DCYSCORE cards).

https://indico.cern.ch/event/365567/contribution/9/material/slides/0.pdf

Sum the data files (flair tool) and look at the **_sum.lis or **_tab.is file where you can find the averaged values with statistical uncertainty for all radionuclides.

You may also want to have a look at the presentation on electromagnetic interactions (see the card PHOTONUC necessary to activate nuclear interactions in particular) and the presentation on BIASING to enhance such reactions ( LAM-BIAS). You can consider different photon/electron thresholds for the prompt transport and residual radiations transport (which you may totally kill if you only look at radionuclides) with the RADDEDCAY card.

Cheers
Joachim

Subject: [fluka-discuss]: how to calculate the content of residual nuclei

Dear all,

I have a question about the content of residua nuclei after irradiation and
my problem is as follows:

An Iron block was irradiated by energy of 1.62GeV electron with intensity of 6.25e10/s for 8 years and cooling time is one day. now I can use RESNUCLE card to calculate the residual nuclei types and the induced activity of them, but i don't know how to calculate the contnet of a given residual nuclei after irradiation, 56Mn or 55Fe for instance.

Can fluka calculate the content of residual nuclei and how to do that.

Thanks in advance.
