Hello,
You assign 3 decay times to 3 detectors, each card overwrites the
previous one and that's the reason why you have only one data set when
your simulation works.
Do you have the latest version of FLUKA release ? There was a bug using
RADDECAY card, problem which was fixed since.
Please flollow that link :
http://www.fluka.org/web_archive/earchive/new-fluka-discuss/0418.html
and maybe this one :
http://www.fluka.org/web_archive/earchive/new-fluka-discuss/0406.html
Best regards.
Sebastien.
