Abstract The experimental evaluation of photon radiation interaction with charged material was undertaken. Gamma and X-ray radiation was directed at graphene deposited on copper foil with a constant electrostatic charge. The radiation counter measured changes in the radiation intensity after passing the graphenous slab. It was confirmed that additional charge can increase the total cross section of photon interaction with matter, and the relative reduction of radiation intensity by (0.42 ± 0.15)% per 10-5 C/cm2 on the single slab proved that it is possible to construct thin and lightweight radiation shields. This result is important for radiation protection during deep space travel, for example.
