Never come across that one before.
One can't imagine a ground-supported slab settling to the point where it tears the dpm.
But if the slab runs onto the inner skin, then surely any settlement of the slab would result in leverage on the wall. So if the residents were not to be slowly killed by radon, they would perhaps be more quickly despatched by collapsing masonry!
Just my humble opinion.
