1 MeV fluences?

Dear Fluka experts,

I see that there is now the option to score directly 1MeV neutron
equivalent fluences, which I think is a useful feature, that I would
like to use. But I'm not sure I understand the conversion damage
values for neutrons found in "sidan.dat". There are 3 data sets
corresponding to Si28, Si29 and Si30, which are presumably combined
with some weighted average according to isotopic composition of
Silicon. However, when I look at "official" Si damage values
(produced by ROSE/RD48), which can be seen in: http://sesam.desy.de/
members/gunnar/Si-dfuncs.html , they simply have one neutron data
set. Is this the weighted average? I notice you've taken the pion
damage values from the ROSE source, so would like to know why the
neutrons are treated differently?

Thanks, Ian
