Good evening, first of all, I wish you have a happy weekend!
My question is as follows: How can I obtain the environmental dose equivalent generated by a specific region through FLUKA. In detail: I set up a tank and put a circular cylinder in front of it (assuming the half is emptied in the middle), and then I let the source that can cover the whole cylinder into the tank through the cylinder. Finally, I just want to get the effect of the photons produced by the water tank or the cylinder on the dose equivalent of the treatment chamber!
The following two figures are the dose equivalents I simulated with PHITS. The first one is the photon source of the cylinder, and the second one is the second photon source produced by the water tank.
I am afraid that people who usualy answer here do not understand your question, especially the description of the tank and the source.
Also the relation between the dose rate map in PHITS and the FLUKA contour plot is not clear to me.
For the question on normalisation, FLUKA gives the dose rate in pSv/primary. You would have to know how many primaries per year are hitting the target (or emitted by a radioactive source) to calculate the annual dose.
And finally, the correct name for H*(10) is “ambient dose equivalent”.
