You have to remember that Neutron back scatter units measure the hydrogen density so it is not really measuring the top of the foam.  The gamma detectors will respond to anything that is in between the gauge and the radiation source (ie. the top of the foam).  The gamma system is better in determining exactly where the top of the foam is actually located.
