Nondestructive analysis of a porous inhomogeneous, generally cylindrical object such as a soot, boule, comprised of n known components where n is an, integer, is achieved by scanning the boule with a beam comprised of photons, each having a distinct energy within one n-1 energy groups. The intensity of the photons within each of the n-1 energy groups leaving the boule is detectedby a detector and is measured by a pulse height/scaler analyzer at each of a plurality of separate heights ti of the beam as measured from the center of the boule. A computer determines each of n-1 attenuation coefficients µ1(r), µ2(r),...µn(r), representing the attenuation of the intensity of the photons in each of …
