For the structures irradiated by protons with energies of 100 MeV and 1 GeV, radiation resistance was estimated. The comparison of the results of radiation resistance under irradiation by protons and reactor neutrons at fluencies from 1018 to 1019 cm−2 was carried out. It is shown, that endofullerenols are more stable under the proton and neutron irradiation than initial endofullerenes. The molecules containing Eu, Gd and Sm with large thermal neutron capture cross sections were found to be the most stable under neutron irradiation.The mechanism of rebuilding of secondary endofullerenols Eu, Sm, Gd, as well as other factors’ influence on radiation resistance are discussed.</p></abstract><kwd-group xml:lang="en"><kwd>fullerenes</kwd><kwd>endometallofullerenes</kwd><kwd>fullerenols</kwd><kwd>fullerene complexes with biopolymers</kwd><kwd>radiation resistance</kwd><kwd>proton irradiation</kwd><kwd>neutron irradiation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Piotrovsky L.B., Kiselev O.I.
