[Gate-users] Strange Dose Profiles

[Ashok Tiwari]

Hi Christopher, 

How did you define the dose actor for P-32 beta emitter? I suggest you to check the parameters of the dose actors (Position, VoxelSize, Resolution, Size). Define the size of dose actor as, size = voxel size times the resolution of the dose matrix. If you want to set your dose actor in the center of spherical phantom then set the position as 0 0 0 mm.

I’ve done dose measurements for P-32 radionuclide in vacuum, and measured about 10^(-15) Gy deposited by each primary particle.
