Claims

1. A METHOD FOR TESTING THE MATERIALS FORMING A TERRESTRIAL SURFACE AREA, WHICH METHOD COMPRISES:

PRODUCING FROM A SOURCE WITHIN A TESTING APPARATUS NUCLEAR RADIATIONS OF A FORM WHICH WILL INTERACT WITH THE MATERIALS OF THE AREA, PROVIDING THE TESTING APPARATUS WITH A DETECTOR OF NUCLEAR RADIATIONS, SAID DETECTOR BEING SPACED FROM THE SOURCE, SPACING THE PORTION OF THE TESTING APPARATUS CONTAINING THE SOURCE AND DETECTOR OF NUCLEAR RADIATIONS A PREDETERMINED DISTANCE ABOVE THE SURFACE OF THE AREA TO BE TESTED AND SEPARATED THEREFROM BY AN AIR SPACE, TRAVERSING THE SURFACE FOR THE TEST AREA WITH THE TESTING APPARATUS, CONTINUOUSLY DETECTING AND RECORDING THE INTERACTION OF THE MATERIALSA FORMING THE AREA WITH THE NUCLEAR RADIATIONS THEREBY PROVIDING A CONTINUOUS LOG OF THE AREA BEING TESTED.
