Wellington Branch Event – XRF101: Practical and Theory of Using a Field Portable X-ray Fluorescence for Contamination Investigations

Portable X-ray fluorescence spectroscopy (XRF) is a valuable tool in the toolbox for contaminated land professionals allowing for in-field screening of heavy metals. However, there are constraints with its use and handled poorly it can give inaccurate results.

This XRF 101 session offers the chance to hear the underlying theory on using a portable XRF, key considerations in calibrating and sample preparation and how to interpret and validate results.

Led by Dave Bull, a principal author of the MfE guide on Field use of X-ray fluorescence spectroscopy for investigation of contaminated soils, the session will mix theory, case studies and hands-on experience with the equipment to give an introductory session, as well as learning for more experienced operators, on fitting this method into site investigations.

The event will finish with networking and chance for questions and answers at a local brewery.
