Re: Can a 1cm-thick concrete wall absorb so many photons and photoneutrons?

Dear Danny,
  I was too fast answering your email!I have looked at your input again and
I have found that the real problem is NOT that you have defined the
REGION INRCC to VACUUM (sorry for the inconvenience!) but in your
geometry definition.
You have defined:
RCC outrcc 0.0 0.0 99. 0.0 0.0 32. 26.
RCC inrcc 0.0 0.0 99. 0.0 0.0 32. 25.
and then
OUTRCC 5 +outrcc
INRCC 5 +inrcc -water
I think that the correct one should be:
OUTRCC 5 +outrcc-inrcc
and then
INRCC 5 +inrcc -water

Please, try and let me know.
Ciao
Andrea
