<p>Hello all,</p>
<p><br>
</p>
<p>I am trying to take into acount alpha and beta emissions, apart from gammas, in a SPECT simulation. So far I have only gammas emitted from my source and I would like to take into acount the alphas and betas that my source emits, as well. For this purpose
I have the full spectrum of emissions (gammas, alphas, betas) of the radionuclide that interests me (it is Actinium 225 actually) taken from MIRD. </p>
<p><br>
</p>
<p>However, in the GATE manual I found that this is possible for voxelized phantoms. In my study I am using a non voxelized phantom (NEMA IQ phantom), and I have sources confined in each out of six spheres, but only gamma emission so far.</p>

</p>
<p>Any help or suggestions are welcomed,</p>
