if I understand well, you can resolve this by first doing a subtraction of
a cylinder of the same section, to the cylindrical lead shield at right angle,
and then place the cylindrical detector at the same level of the shield
(i.e. in the same mother volume) such that it passes through.

Cheers, Gabriele
