Nuclear radiation apparatus and method for dynamically measuring density of test materials during compaction.

IT INCLUDES A GALGA (20) THAT INCLUDES A NUCLEAR RADIATION SOURCE (31) AND MEANS OF NUCLEAR RADIATION DETECTION (32) WHICH ARE ASSEMBLED IN SPACED RELATIONSHIP, FROM THE SURFACE OF THE TEST MATERIAL TO FORM AN AIR ZONE BETWEEN THEM. THE GALGA ALSO INCLUDES MEANS TO MEASURE THE SIZE OF THE AIR ZONE BETWEEN THE TESTING MATERIAL AND THE SOURCE AND DETECTOR SYSTEM AND MEANS TO COMPENSATE THE EFFECT OF THE SIZE OF THE AIR ZONE TO SO OBTAIN THE DENSITY OF THE TESTING MATERIAL.
