The use of ionizing radiation is an effective tool for stimulating a controlled modification of structural and conductive properties of nanomaterials. The paper presents the results of studies of the influence of Ar 8+ ions irradiation with an energy of 1.75 MeV/nucleon with a fluence from 1 × 10 9 to 5 × 10 11  ion/cm 2 on structural and conductive properties of Zn nanotubes. It was established by scanning electron microscopy, X-ray diffraction and electron diffraction analysis methods that irradiation with Ar 8+ ions makes it possible to modify the crystal structure of nanotubes, increasing their conductivity and decreasing the resistance of nanostructures, without destroying the structure. Zn nanotubes with a diameter of 380 nm were synthesized using the electrochemical synthesis method. An analysis of dislocations density change and stresses in irradiated nanostructures indicates that a deformation in structure and subsequent relaxation of internal stresses are observed. Also, it is shown that as the irradiation fluence increases, an insignificant increase in the parameters of the unit cell is observed, which may be due to an increase in the contribution of thermal vibrations.
