Question 1

What is X-ray fluorescence testing in real estate?

Accepted Answer

X-ray fluorescence (XRF) testing: a non-destructive analytical technique used to determine the elemental composition of materials. In RE: XRF is primarily used to: detect lead-based paint in buildings constructed before 1978 (the year lead paint was banned for residential use). The XRF analyzer: emits X-rays that interact with the surface material and measures: the resulting fluorescent X-rays to determine: the lead content. The test: is fast (results in seconds), non-destructive (no sampling required), and accurate (can detect lead at levels below the EPA action threshold of 1.0 mg/cm²).
