Filtering daughter nuclides in decay chain

Thanks for the detailed explanation.

I have one more doubt, whether there is any way such that only U238 can be used as a source i.e. no contribution from its daughter nuclei, other than importing its separate spectra in source.f.


Dear Rohit,

The solution with sampling from the dedicated source.f routine for a given radioisotope is the easiest one. Nothing can be done more ‚Äėautomatically‚Äô in FLUKA for now, to cut off daughter nuclei, in a semi-analogue mode of a decay (RADDECAY card).
However, the topic is interesting and it may happen that an easier solution to this issue will come in future.

Best regards,
