[Gate-users] Dose Uncertainty

[Juan Sebastian Useche Parra]

Hi Gabriel,

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.

Cheers,

Dear GATE community,

I am working on a project related to Dose Uncertainty. I realized that both, absorbed dose and energy deposited uncertainty are equal. I expected to obtain different values ​​between both results (inversely proportional to the absorbed dose). I will appreciate some help on this subject.

Best regards,
Gabriel
