Dear FLUKA experts: Using the FLUKA code, I am calculating the dose absorbed by a detector made of A-150 plastic, shaped as a cube with a side length of 19.19 cm and a volume of 7067 cm³. For this, I am using the USRBIN command with WHAT(2) = DOSE (ID - 228). Is it necessary to divide the data obtained from the USRBIN command by the volume of the detector to get the correct result? Best regards Konstantin ---

It depends on the USRBIN type (WHAT(1)). If you scored by region, you must divide the resulting value by the region volume in cm^3 (this way getting the average dose over the detector, in GeV/g). If you adopted a Cartesian or cylindrical scoring mesh, the resulting values are already in GeV/g, since the mesh bin volume is known to FLUKA, which used it. ---
