DOSE-EQ output quantity

Dear FLUKA experts,

I’m trying to calculate ambient dose equivalent H(10) produced by a 137Cs point source at 1m distance. For this purpose I created a probe which is a simple sphere with a 0.5 cm radius at 1m distance from the source. For H(10) calculation I used USRBIN DOSE-EQ card with REGION mesh. A far as I understand, for the REGION mesh the FLUKA code calculates the total track length in cm and then multiplies it by conversion factor in pSv*cm2. Am I correct that for such initial conditions my calculated output for USRBIN DOSE-EQ with REGION mesh will be in pSv*cm3 and to get a proper value of H(10) I must divide the result by the volume of my probe? Could you please clarify the output units of USRBIN DOSE-EQ with REGION mesh?

Thank you in advance

Dear Alexy,

your thinking is correct. The USRBIN results with Region meshes need to be normalized with the volume of the region by the user to get the expected unit.
