An Irradiation Projector, also known as a Rad-Cleanser or Irad-Cleanser, is a class of projected radiation devices used as potent anti-personnel weapons. These weapons were a relic from the Dark Age of Technology and were used exclusively by the forces of the Mechanicum, particularly during the Great Crusade and Horus Heresy eras of the late 30th and early 31st Millennia.
Any type of Irradiation Projector is commonly comprised of a bulky generator unit that terminates in a dish-like projector that unleashes a powerful blast of deadly cross-spectrum radiation. Any organic victims caught in the blast of such a weapon suffer an appalling death as they are boiled alive from within -- their tissues blasted apart on a cellular level by the potent ionising radiation. While thick barriers of solid matter between the beam and the target can provide some protection, victims who survive the initial blast will often die later of extreme radioactive contamination.
Types of Irradiation Projectors
The following are all known types of Irradiation Projectors that were once used by the ancient Mechanicum:
- Lucifex Pistol - A pistol-type Irradiation Projector, these rare weapons were only carried by a high ranking Magos, such as a Magos Prime.
- Rad-Cleanser or Irad-Cleanser - A rifle-sized Irradiation Projector, this weapon was the most common type carried by Mechanicum forces. It was commonly found in use by many Mechanicum units such as Myrmidon Secutors and Destructors, Scyllax and Vorax Battle-Automata, the mighty Questoris Knight Magaera, Questoris Knight Styrix and the various Magi of the Omnissiah.
- Irradiation Engine - The Irradiation Engine was the largest known Irradiation Projector used by the Mechanicum. These weapons were known to have been used by the fearsome Myrmidon Destructors and by the Macrocarid Explorator heavy transports.
