SYNCHROTRON RADIATION X-RAY FLUORESCENCE ANALYSIS OF ELEMENTS IN HUMAN GASTRIC CANCER

Synchrotron radiation microprobe XRF analysis has been used in the multielements analysis of human gastric cancer tissues. Elements of P, S, Cl, K, Ca, Ti, Mn, Fe, Cu, Zn, Se, Br and Rb were detected. The relative concentrations of P and K in cancer are higher than in normal tissue, but it is contrary for Cl, Ca, Se and Br.
