I have a cask containing radioactive scratch material from a BWR core and I have to calculate the ambient equivalent dose rate H*(d) at certain points outside of the cask, for example at 1m from its surface, at middle height.
I'm thinking of implementing the ICRU sphere (whose diameter is 30cm) in the geometry and then tallying the dose equivalent rate in a small volume centered around the point pointed to by the radius of the sphere, oriented towards the source (f.e. I would say horizontally if I place the detector at middle height) and at depth d.
The dose rate is in principle a point quantity but it's clear that with the Monte Carlo I can only tally the dose in a volume, as small as it can be. So I am thinking of a small sub-sphere centered around the over mentioned point.
How large should the sub-sphere be ? In principle it should be as small as possible, but if it is too small then it's going to take too much time in order to obtain a good statistical quality. Does anybody have experience ?
