Cronau radiation

"Do the sensors detail any instances of ships jumping to lightspeed?''" "''None, sir. No instances of Cronau radiation—though the interdiction field would make that a long shot, in any case."

- Wilhuff Tarkin and a comm specialist Cronau radiation was a type of radiation emitted by starships upon jumping into hyperspace. The Imperial-class Star Destroyers of the Galactic Empire were equipped with sensors that could detect Cronau radiations, thus enabling their crews to detail instances of vessels entering hyperspace.
