This is the paper that is being used to link the presence of Graphene in the environment or in the vaccinated and the detection of some kind of ionizing radiation.

Basically it says that Graphene can be used to increase the stimulation of radiation of surface plasmon polaritons when hit by an electron source, by three orders of magnitude, turning them into effective sources of Cherenkov radiation.

I know there’s no direct way to relate five gee radiation to this, but it provides an interesting starting point of research.
