US 2003/0213315 A1 · Selective profiling of bulk building material for characterization using a concrete contamination profiling technology

Abstract

Disclosed is a method and system to characterize the contamination levels of bulk materials, the method comprises drilling into the material, sampling material from the drill point at predetermined intervals, and analyzing the sampled material. Such an embodiment may be accomplished by using a drill with a specialized cutting and sampling head, drill bits, a sample collection units and a vacuum pump. The embodiment in conjunction with portable radiometric instruments produces a profile of radiological or chemical contamination through the material being studied.

Claims19

Dependent claims

A method of analyzing the amount of contaminants in building material, the method comprising:

drilling into contaminated material an incremental distance to create a powder from the contaminated material,
collecting the powder during the drilling by using a continuous vacuum force, and
analyzing the collected powder to determine the amount of contaminants in the contaminated material at the incremental distance.

Dependencies are inferred from the claim text.
