Abstract: Non-invasive methods of express analysis for mass monitoring of pathological states of human organism have been developed on the basis of X-ray fluorescence (XRF) elemental analysis of hair, nails, tooth enamel and skin. In addition, methods have been developed for studying sample preparations with the use of a universal X-ray fluorescence spectrometer mounted on a VEPP-3 storage ring. Data have accumulated over several geographical regions (Moscow Region, Chelyabinsk, Middle Asia, Novosibirsk Region, Maritime Region). The data of XRF analysis of hair samples from patients and animals mirror reliably differences in element concentrations. The methods can be useful in clinical medicine.
