It was used primarily as a method of interfering with sensors and transporter systems, (; ) seen as a byproduct of alien appearances, (; ; ) used for medical purposes, () and used as a basis for weaponry (although it could result in instability in the weapon). ()

High levels of thoron radiation were found around the Nechisti shrine. ()

Antithorons can be generated on a large scale by  starships and have been used both to interfere with force fields and decontaminate planetary crusts prior to mining. () Thoron radiation may also hinder transporter operations, presumably by interfering with sensor readings.
