A photo-optical and radiophysical study into the destruction process of the internal structure of plexiglass (PMMA) after its exposure to an ionizing electron irradiation and a subsequent external mechanical point impact was carried out. Enlarged macrophotography of the picture of the radiation-mechanical internal destruction of plexiglass was performed at different shooting modes. An analysis and explanation of physics of the formation mechanism of the tree-like branched fractal structure of PMMA destruction is carried out based on the dynamics of impulse compression and a spherical single wave arising at the impact action. The radiophysical parameters of PMMA with radiation damage were measured using the waveguide method in the microwave range.
