[Gate-users] energy deposition higher than emission!!!!!!!!!!!!!!!!!!!!!!!!

[AliAsghar Parach]

Dear gate users,
I beg your pardon, i sent similar email several weeks ago but i did not
receive any response for this problem. in summary i questioned tow things:

1-I used GATE for dosimetry application. When i start the simulation in
GATE4 it successfully completed with no error but there was seen absorbed
dose in Vacuum out of phantom (my phantom is a sphere with the point source
in it's center).

2- when i calculate the total energy deposition in phantom (from the
absorbed dose*m) the total deposited energy in phantom is higher than energy
emitted from the point source in phantom center.
note:
-i use voxelised phantom and source.
- i translate the point source to real center of phantom (according to gate
user's guide).

help me to find out the reason of those cases in GATE.
