Radium Weapons are a type of weapon used by Adeptus Mechanicus Skitarii. These weapons are so volatile that they eventually kill their wielders. Their purpose is to not only slay the enemy with a blast of radioactive force, but to also render the battlefield a deadly rad-waste. Each weapon's bullet cylinder is so thoroughly bathed in radium that a volley can cause a localized radiation storm. Those inside soon find their flesh blackening and sloughing away.
