METHOD FOR INSPECTING AN INFRASTRUCTURE, COMPTON SCATTERING INSPECTION DEVICE AND METHOD OF OPERATING THEREOF

摘要

The method is for inspecting an infrastructure having a corrugated pipe atleast partiallysurrounded by soil. The corrugated pipe has a cylindrical wall which iscorrugated along alength thereof and forming a longitudinally extending series of corrugations.The methodgenerally has the steps of emitting, outwardly from the interior of thecorrugated pipe, abeam of radiation particles directed towards a given voxel positioned beyondan inner faceof the cylindrical wall and along a scanning plane parallel to an orientationof individualones of the corrugations of the cylindrical wall; detecting backscatteredphotons scatteredback from the given voxel and along the scanning plane; and generatinginspection databased on the detected backscattered photons associated with the given voxelfor use ininspecting the corrugated pipe.
