What Is XRF Lead Testing?
XRF stands for X-ray fluorescence, a non-destructive testing method used to detect lead-based paint on surfaces. During an inspection, a certified professional uses a handheld XRF analyzer to scan painted areas and determine whether lead is present. The device sends low-level X-rays into the surface. If lead is present, the material emits a specific energy signature that the device detects and measures. The results appear instantly on the screen. Key features of XRF testing:- Non-destructive and safe
- Immediate results
- Highly accurate
- No need to remove paint samples
- Accepted by government and regulatory agencies
