Physics Seminar Series 293 (1/20/17)

Mihai R. Gherase, California State University, Fresno

Abstract:

For the past 50 years medical x-ray fluorescence (XRF) studies highlighted the importance of trace elements metabolism and toxicity to human health. The talk will introduce the physics behind XRF and place past and current medical and biological applications in a broad scientific context. Instrumentation, methods, and results of several studies focused on the measurements of arsenic and selenium in skin phantoms and human nails and lead in bone phantoms will be presented. Time allowing, the capabilities of the microbeam XRF unit recently developed at Fresno State will be presented in connection with present and future research interests.
