The theoretical investigations on the concept of new active radiation shields based on graphene are discussed. The cross section of the gamma and X radiation interaction with a charged graphene layer is presented and used to calculate the linear attenuation coefficient of the proposed shield. Finally, the technical concept and potential applications of the graphene shield, as well as some potential difficulties, are discussed.read more

Theoretical estimation of the increase in the photoelectric effect cross section of the X-ray interaction with charged graphene
TL;DR: Theoretical perspective discussions about negatively charged graphene slabs and their radiation properties are presented in this article, where 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.
