Popis:	The rates of poly (vinylidene fluoride) (PVDF) degradation under synchrotron (SR) and conventional X-ray radiation have been measured and compared. NEXAFS spectra of fluorine show significant changes in their shape and intensity with elevation of radiation dose (or duration of SR exposure). Non-monochromatic AlK α radiation and the flow of secondary electrons accompanying it also cause surface degradation of PVDF. XPS allows one to measure relative content of fluorine by three ways: via relative intensities of F2s/C1s, F1s/C1s, spectra and using the features arising due to of C1s peaks in CF 2 and CF groups.
