<p class="MsoNormal"><span lang="EN-GB" style="mso-fareast-language:EN-US">From my knowledge, if you are using the doseActor, the uncertainty is inversely proportional to the number of particles that were absorbed in your volume/voxel. Therefore, it makes sense
that for the dose and the energy, the uncertainty is the same. You have to consider that the uncertainty given by the doseActor is relative ( i.e. sigma/value), so you need to multiply by the dose (energy) value given by the actor.<o:p></o:p></span></p>

proportional to the absorbed dose). I will appreciate some help on this subject.<o:p></o:p></span></p>
