Theoretical perspective discussions about negatively charged graphene slabs and their radiation properties are presented. It is shown that additional electrons in graphene, injected in a charging process, can enhance the value of the total cross section of photon radiation interactions, especially for X-rays and lower energies. A detailed discussion about the photoelectric effect on electrons trapped in quantum wells in graphene supplements the investigations on light carbon radiation shields. It is concluded that hundreds of parallel graphene slabs would give a significant contribution to modern radiation protection.
