These range from threatening to blow up a nuclear power reactor, to spreading radioactive waste in a target building of water supply, or arranging to illegally dump nuclear waste.
The Ignalina, a larger version Chernobyl-type reactor, was shut down following the threats. Kestutis Mazuika, who claimed to work for a secret Lithuanian organisation called NUC-41 W, was arrested in Sweden, after he threatened to blow up Ignalina unless paid $8 million. Reportedly, murderer Dekanidze's father, Georgy Dekanidze, had also threatened to blow up the nuclear plant. The plant was closed, following a tip from the Germans, from Dekanidze's "Vilnius Brigade" gang.
A joint Swedish-Lithuanian team found no explosives at the plant, and it was re-started without incident. Ignalina was the first incident of a mob threatening to blow up an atomic reactor.
The Italian environmental group Legambiente collected extensive documentation indicating that Giorgio Comerio, owner of a variety of businesses in Italy and Malta, provided radioactive waste disposal, and was part of the illegal mob business. Comerio, partly funded by the international Euratom agency, and with $ 125 million of United States and Japanese money, disposes of radioactive waste in 16 meter-long torpedoes which penetrate deep into the sea bed, each one carrying up to 200 tons of radioactive waste.
Italian magistrate Domenico Porcelli, said that a
substantial part of this waste ends up at the bottom of the
Adriatic and Mediterranean seas, threatening to turn Italy into a
"nuclear cemetery."

Legambiente "also said that the Italian secret services had leads on
traffickers, the mafia and representatives of Third World
governments all linked to the nuclear trade, while Bologna, in
northern Italy, has become an illicit international uranium
exchange."
