Jakmanite is a radioactive element that isn't normally picked up by the sensors of a Galaxy-class starship.
Furthermore, along with Invidium, Saltzgadum, Selgninaem and Lucrovexitrin, it is one of only five undetectable substances that can exist in a nitrogen-oxygen atmosphere and can alter the molecular structure of glass.
Jakmanite has a half-life of about fifteen seconds and was thereby ruled out as having caused the malfunctions aboard the Enterprise at the end of 2366, as there wouldn't have been enough time to spread the substance all over the ship. (TNG: "Hollow Pursuits")
