A Caution on Using XRF Alone for the Identification of Problem Drywall
X-ray fluorescence (XRF) is an analytical method using emission spectroscopy to identify the presence of specific elements in most materials. Every element has a unique emission signature, making it possible to quantify the presence of an element by the relative strength of the emission. Instrumentation has evolved to the point where hand-held XRF can be […]
