Distronic toxaemia

Distronic Toxaemia was a disorder that quickly causes fatigue before it kills the victim. It can be obtained by exposure to Distronic explosives, which are usually used in explosive rockets. Near the end of the Thousand Year War on Skaro, the Thals prepared to develop a rocket with a Distronic warhead in order to destroy opposing kaled Dome. The Thals using captured prisoners, including Sarah Jane Smith and [Sevrin]] as an expendable work slave labour to load the dangerous element into the warhead. (DW: Genesis of the Daleks)
