Abstract
A cone-tipped penetrometer for in situ analysis of soil or sediment by X-ray fluorescence spectroscopy. Rather than using a radioactive source, a miniature x-ray tube is powered by a filament isolation transformer located inside the penetrometer pipe which has an outside diameter of about 2 inches or less. The x-rays pass out through a special x-ray transmissive window, such as a low metal impurity-containing high strength boron carbide, into the soil or sediment below the surface and the resulting x-rays from the metals in the soil or sediment return through the window to a detector. The signal is transmitted back up to the surface where the x-rays are quantitatively analyzed to determine the concentration of metals in the soil. This real-time in situ x-ray fluorescence spectroscopy of soil or sediment samples permits field analysis of hazardous waste sites and other underground soil and underwater sediments.
