Abstarct: In the past few decades, revolutionary developments of science and engineering have moved at a very fast pace towards synthesis of materials, are considered. Nanostructured materials include a broad class of materials in the form of thin films, coatings, powders, or bulk materials. As the grain size decreases, there is a significant increase in the volume fraction of grain boundaries or interfaces, which strongly influences the chemical and physical properties of the material. The radiations emitted by radioactive nuclei can have wide applications to modify properties of the materials. Irradiating solids with energetic particles is thought to introduce disorder. But recent irradiation studies have demonstrated that radiation can play a crucial role in the engineering of nanomaterials. The radiation effects could be a way for the design of new materials. In this thesis, the first step is to calculate the amount of absorbed dose on the surface of materials, using Geant4 simulation code. Knowing this dose one can predict changes in structure and properties of materials. In the next step, the growth of nanostructures using radiation from radioactive materials were investigated. For this purpose copper samples were used. sources was used in the experiment. After the expriment, the samples were taken SEM images. The surface morphology changes, the effects of radiation on the surface of the material was found.
