Field demonstration of the SCAPS XRF Metals Sensor

摘要

The SCAPS XRF Metals Sensor adds metals detection capability to the DOD Site Characterization Penetrometer System (SCAPS). It works using X-ray Fluorescence (XRF) to detect all metals above calcium in the subsurface soil. The sensor head contains a miniature x-ray tube and cooled solid-state detector to achieve performance comparable to laboratory units in a down-hole sensor. The sensor may be pushed to depths as far as 150 feet by the cone penetrometer system and is designed to detect metals at concentrations below 100 ppm in all soil types regardless of moisture level.
