ABSTRACT:
An apparatus and method for detecting changes in a physical property of the material beneath a large storage vessel, such as a landfill. The apparatus includes one or more tubes defining elongate channels in the material beneath the storage vessel. A sensing probe is moved through the channel while taking and collecting measurements of the physical property of the material in the vicinity of the probe. Typically, moisture and/or density may be measured using conventional nuclear sources and associated detectors. The measurements are compared with reference data to thereby detect a change indicating a leak in the storage vessel.
