Distronic explosives were powerful but unstable weapons, used on many worlds as components of explosive warheads attached to missiles. The explosives were highly dangerous, even before they were detonated, causing anyone exposed to unshielded distronics to develop distronic toxaemia. In just a short time, this disorder caused fatigue and killed the victim. (TV: Genesis of the Daleks) As distronic explosives decayed, they became unstable and when subsequently exposed to sunlight, were prone to spontaneous detonation. Because of this instability, distronic explosives were at one time banned throughout the galaxy. (COMIC: Smart Bombs)
