[Gate-users] dose problem2

[AliAsghar Parach]

Hi gate users.
I installed gate3.1.2 successfully in fedora8.
I use gate for dosimetry application in NCAT phantom. when simulation was
completed the output dose file (ncat.bin) was truely created.
but the amount of dose in out of body was not zero (the medium in out of
body was set tovaccum and it's activity was set to zero).
is it true dose distribution in vaccum by gate?
is my simulation result reliable?
how can i find it's cause and overcome my problem?

best regard
