Radiation/Legends

Radiation was a byproduct of many natural and artificial substances. Deadly items that were of this nature were deemed radioactive. Radiation encompassed the entire electromagnetic spectrum, including gamma rays, ultraviolet, infrared, and microwave radiation. It was categorized into five phases, with Phase 5 being the deadliest.

Doses of radiation could produce genetic mutations in creatures, resulting in mutants and other ghastly beings such as Coruscani ogres.

Sources of radiation
Natural radiation of all kinds was emitted from stars and interstellar gases, as well as certain materials and elements such as uranium, and even volcanic lava on various planets such as Qat Chrystac.

Radiation was also weaponized, and used in launchers that delivered payloads of radioactive material.

Radiation would also be emitted as propulsion from certain types of spacecraft as ion particles in twin ion engines, and from certain atmospheric speeders like the Koro-2 all-environment exodrive airspeeder.

It was also produced from the explosion of nuclear bombs and neutron bombs. If a Hypermatter reactor exploded, it could produce a cloud of radioactive dust.

Imperial TIE fighters also used radioactive fuel.

History
During the Invasion of Naboo and the subsequent Clone Wars, radiation launchers were used by the battle droid forces of the CIS. They were known to have devastating effects.

The Galactic Empire created the elite Radiation zone assault trooper, or Radtrooper, to work in environments saturated in radioactivity. A radiation bomb was also used by Commander Thrawn in 27 BBY to eradicate life aboard Outbound Flight.

Radiation detectors were worn around 4 ABY to alert the wearer while in the presence of high levels of radiation. The bounty hunter and slaver Bossk wore a radiation detector on his hip while he inspected Boba Fett's ship Slave I for hidden traps.

The planet Tund was turned into a virtual wasteland as a result of radiation emitted from an electromagnetic torpedo, which was unleashed by the last Sorcerer of Tund, Rokur Gepta.
