XRF readings:
Lead: 5000 ppm · Cadmium: 0 ppm · Arsenic: 0 ppm
Verdict: High: FluoroSpec test required
This Kitchen table positive for 1,400 ppm Lead, yet overlooked by an inspector as an exposure source for a child’s Blood Lead Level. tested at 5000 ppm lead, significantly elevated. The bioavailability question (can this lead reach a person?) depends on whether the lead is locked into a fired matrix or sitting on a painted surface.

XRF measures lead presence on the surface. It does not measure whether that lead can reach a person. That distinction matters for how you should react to this number. Read the full primer.
