On the XRF device they use:

"Any new soil results discussed in this release have been analysed in the field using a handheld XRF machine. - The details of the instruments used include: - Olympus Innov-X Delta Premium portable XRF analyzer is used with a Rhenium anode in soil and mines mode at a tube voltage of 40kV and a tube power of 200µA. The resolution is around 156eV @ 40000cps. The detector area is 30mm2 SDD2. A power source of Lithium ion batteries is used. The element range is from P (Z15 to U (Z92). A cycle time of 120 seconds Soil Mode was used and beam times were 40 seconds. A propylene3 window was used. No calibration factors were applied. - Blanks and standards are analysed at after every 5th XRF sample. - Surface XRF analysis of this type is used to determine element anomalism relative to a regional background. Concentrations are c o n s i d e r e d approximate only and anomalism is determined as statistically relative to the determined regional background levels."
