Can XRF detect lead?
Both XRF hand-held lead detection devices can be used to detect lead in the soil. In addition, they can be programmed with software that allows them to detect highly toxic elements such as arsenic, cadmium, chromium, copper, mercury, nickel, selenium, silver, vanadium, and zinc.

What is XRF Lead Testing?
XRF lead testing involves a surface-by-surface investigation to determine whether lead-based paint is present in a house, dwelling unit, or residential building. The inspector holds the XRF analyzer directly on each painted surface in order to take measurements, which are then classified based on EPA / HUD standards.
Which lead test is the most accurate?

Does lead paint fluoresce?
Lead white and lithopone feature intense fluorescence due to the binders they are mixed with. Among the four white pigments only titanium white is characterized by the lack of fluorescence in any of the binders, thanks to its strong absorption band in the UV region.
What is XRF lead-based paint?
An XRF is a portable x-ray machine that is frequently used by lead inspectors. XRF stands for x-ray fluorescence. It can see through a surface and tell if lead paint is underneath. XRF testing is non-destructive, fast, and cost effective.

Prices increase based on surface areas and square footage. Expect to pay an extra $150 to $300 to add a water or soil test.
What is an XRF device?
An X-ray fluorescence (XRF) spectrometer is an x-ray instrument used for routine, relatively non-destructive chemical analyses of rocks, minerals, sediments and fluids. It works on wavelength-dispersive spectroscopic principles that are similar to an electron microprobe (EPMA).
How reliable are lead test kits?
The FDA reported that the swabs were able to detect the presence or absence of lead in 96.6% of the pieces tested. The NIST found that the swabs were able to detect lead in paint as well as or better than other methods.
