This is a list of criminal (or arguably, allegedly, or potentially criminal) acts intentionally involving radioactive substances. Inclusion in this list does not necessarily imply that anyone involved was guilty of a crime. For accidents or crimes that involved radioactive substances unbeknownst to those involved, see the Nuclear and radiation accidents and incidents.
Murder and attempted murder
The Karlsruhe plutonium affair Johannes M. was convicted of attempting to poison his ex-wife in 2001 with plutonium stolen from WAK (Wiederaufbereitungsanlage Karlsruhe), a small scale reprocessing plant where he worked. He did not steal a large amount of plutonium, only rags used for wiping surfaces and a small amount of liquid waste. At least two people (besides the criminal) were contaminated by the plutonium. Two flats in Landau in the Rhineland-Palatinate were contaminated, and had to be cleaned at a cost of two million euro. Photographs of the case and details of other nuclear crimes have been presented by a worker at the Institute for Transuranium Elements.
The Litvinenko assassination
Alexander Litvinenko died from polonium-210 poisoning in London in 2006. British officials said investigators had concluded the murder of Litvinenko was "a 'state-sponsored' assassination orchestrated by Russian security services." On 20 January 2007 British police announced that they had "identified the man they believe poisoned Alexander Litvinenko," Andrei Lugovoi. On 21 September 2012, a story was posted in various UK newspapers suggesting the existence of an ongoing cover-up by the British Government over the material facts of the case. The report suggests that many aspects of the case may "never see the light of day" due to the significant risk to UK/Russian relations and the implications of the declaration that an act of nuclear terrorism took place on British soil.
Roman Tsepov homicide Roman Tsepov, a politically influential Russian who provided security to Vladimir Putin and others, fell sick on 11 September 2004 after a trip to Moscow, and died on 24 September. A postmortem investigation found a poisoning by an unspecified radioactive material. He had symptoms similar to Aleksandr Litvinenko.
Zheleznodorozhny criminal radiological act An unnamed truck driver was killed by five months of radiation exposure to a 1.3 curies (48 GBq) caesium-137 source (about 15 mg) that had been put into the door of his truck around February 1995. He died of radiation-induced leukemia on 27 April 1997.
Vladimir Kaplun radiation homicide In 1993, director of the Kartontara packing company Vladimir Kaplun was killed by radioactive material (cobalt-60 and/or cesium-137) placed in his chair. He died of radiation sickness after a month of hospitalization. The source of the radiation was found after his death.
