Subspace radiation is a form of radiation associated with subspace phenomena. The detonation of an Omega molecule produced dangerous subspace radiation. As a result, the Omega Directive mandated multiphasic shielding be installed around the warp cores of any responding ships. (VOY: "The Omega Directive") A testing ground for long-range subspace warheads encountered by the USS Voyager in 2378 contained high levels of subspace radiation from the weapons' detonations. This radiation impaired Voyager's ability to form a stable warp field. (VOY: "Human Error") de:Subraumstrahlung
