While they can be a useful survey tool, they typically operate at about ¾” depth and can be susceptible to other elements within the slab such as rebar, certain types of aggregates
Interpretation of '5%' There is nothing wrong with the contents of the Digest as it is actually written. Less than 5% total moisture content at the base of a wall is unlikely to represent severe rising dampness, and around 5% at the base of a wall (the base of a wall means the base, i.e., at the floor/wall junction not 100mm, 250 mm, etc, above!) is a broad guideline to suggest some action
