Abstract : Although synchrotron radiation X-Ray fluorescence (SR-XRF) is among the least destructive analysis methods applied to rare extraterrestrial grains, we have observed radiation damage effects following high flux synchrotron analyses. Track 30 of the IS collector of the Stardust mission , containing 2 candidates dubbed Orion and Sirius was analyzed at ESRF, France, on beamlines ID13 and ID22NI by nano-XRF/XRD scanning methods. Beam damage effects were noticed on both samples and a quantitative analysis of their irradiation history was established , allowing us to propose new experimental protocols as well as fluence limits, minimizing such effects in the future. The purpose of this study is to present these facts, analyze potential damage mechanisms and offer alternatives.
