Is the source you are using a voxelized source ? If so, make sure it is translated to the right place. By default, a voxelized phantom is centered at the origin but a voxelized source is centered at the corner of the enclosing box.<br>
Are you using a back-to-back source, an e+ source or an ion source ?<br>

I installed gate3.1.2 successfully in fedora8. <br>
I use gate for dosimetry application in NCAT phantom. when simulation was completed the output dose file (ncat.bin) was truely created.
<br>
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).
<br>
is it true dose distribution in vaccum by gate? <br>
is my simulation result reliable? <br>
how can i find it's cause and overcome my problem?<br>
<br>
best regard<br>
