Therefore, one has not to expect the "vacuum" Cherenkov effect. If the neutrino outruns its self-radiation, then, according to Kohen-Glashow calculations [23], it would lose almost its total energy for the production of a pair of particles, which has not been observed experimentally.
As a way to make radiation safer and better, Dartmouth began to investigate a scientific phenomenon called the Cherenkov effect in 2011.
