Everything looked great, even when running the macro with mono energetic particles and comparing the results against published literature.</div><div><br></div><div>Recently I decided to have a look at other diagnostic isotopes 99mTc, 67Ga etc and some alpha emitters e.g. 223Ra. I found the marco I was using (originally based on the mouse dosimetry example) did not give results close OLINDA when I simply changed the ion source. Ive got a feeling Im not including all of the required parameters in the Physics and tried the PhysicsList option with out luck.</div><div><br></div><div>Ive uploaded a working example to <a href="http://dropcanvas.com/53wei" target="_blank">http://dropcanvas.com/53wei</a> which is a simple ~100gm sphere I can compare to OLINDAs sphere results. The .xls file is a summary of the results. You can see that for 18F and 177Lu the difference in dose to the sphere is within a few percent. However for 67Ga, 99mTc and 223Ra the difference is large. It appear all positron/beta emitters I model the results or good. For gamma and alpha emitters the results are very different.</div><div><br></div><div>I think the correct PhysicsList I need is QGSP_BIC_EMY (e.g. /gate/physics/addPhysicsList QGSP_BIC_EMY) and it should allow me to simulate gamma, beta and alphas by just changing the ion source. Ive been doing this from the command line like below;</div><div><br></div><div>Gate -a
