The presence of amino acids in comets and meteorites raises questions about how they have been formed in cosmic environments, as well as how long they can survive in outer space; radioresistance is essential information to predict half-lives and make advances on the origins of life studies. The main objective of the current work is to determine, via infrared spectrometry, destruction cross sections of common amino acids exposed to energetic ion and electron radiation. Before sample irradiation, valine vibrational band strengths and their infrared spectral dependence on temperature (10 – 400 K) were analyzed. Apparent destruction cross sections (sigma)d(ap) and sputtering yields (Y0) for glycine, valine and phenylalanine, irradiated by MeV H+, He+ and Nq+ ions and keV electrons, were measured. From experimental data: i) an approximately linear dependence between the apparent destruction cross section and the electronic stopping power (Se) is found: (sigma)d(ap) = (sigma)d + Y0 /N0 = a Sen (where n approximately 1) for MeV projectiles and for samples at room temperature; ii) (sigma)d(ap) preliminary results relative to multi-charged nitrogen ion beams are discussed; and iii) destruction cross section of valine irradiated by keV electrons, as well as its dependence on incident beam energy, on sample thickness and on sample temperature are presented. As a theoretical contribution, the evolution of organic matter damage by charged projectiles, particularly for electron beams, the CASINO-extended model was developed. When compared to experimental results, the model predictions underestimate the damage caused by electron beams, evidence that sputtering and probably some sample characteristics (as crystallographic structure) are involved. As astrophysical implications, cosmic ray half-lives for valine and phenylalanine are estimated to be about 10 million years in the interstellar medium; solar wind half-life at 1 au from the Sun is approximately 3 days for glycine. Aiming to simulate realistic astrophysical materials bombarded by keV electrons, the half-life of valine embedded into water and CO2 ices over a silicate substrate is also predicted.
