Abstract:

This report addresses two sets of issues concerning the use of x-ray fluorescence as a sensor technology for the cone penetrometer. The first group concerns the applicability of XRF to this application, and includes investigation of detection limits and matrix effects. The second group is engineering issues involved with constructing a spectrometer within the physical constraints of the penetrometer. Metals, Sensor, X-ray absorption, Environmental, Penetrometer
