The contaminants of concern are lead, mercury, cadmium and arsenic. Once identified, a land owner can choose not to use the land or address the problem with remedial activity. King, who is based in Washington, and took advantage of the nearby XRF device demonstration to get some field measurements of natural radiation in the area and then near the device in various modes. No problems were detected. This technology provides an efficient and timely analysis for the customer so that they can make their land use decisions. Previously, aerial surveys and excavations were needed to get soil samples that were sent to laboratories for analysis. The increased use of suburban/urban interfaces for agricultural production is one of the reasons this device was brought into service is to detect metal content in soil that people may have put on the land.
