In the University Center of Defense in San Javier, composite sheets based on carbon fiber and epoxy matrix have been prepared, with some of them doped with graphene oxide or with 0.1% graphite from Sigma-Aldritch and manufatured by us.
These sheets were then irradiated with X-rays in the radiodiagnosis service of the Mesa del Castillo Hospital, Murcia, Spain. Radiation absorption measures via image analysis were performed and it has been shown that graphene-doped sheets absorb an important part of the X-ray intensity over a wide range of energy. These experiments were repeated over various ranges of frequency and energy with similar results.
