Gravimetric radiation
From Memory Alpha, the free Star Trek reference.
Gravimetric radiation was the transmission of energy in the form of fast moving gravitons.
In 2376, the USS Voyager encountered high level of gravimetric radiation emitted by a graviton ellipse that was traveling through subspace. The Doctor prepared an inoculant to counter the dangerous effects of gravimetric radiation. (VOY: "One Small Step")
