An investigation was under way on Saturday into Russia's black market trade in radioactive materials amid concern that quantities of polonium 210, the substance that killed former spy Alexander Litvinenko, are being stolen from nuclear sites.
Officials from Britain's Atomic Weapons Research Establishment and Porton Down, the government's Defense Science and Technology Laboratory were trying on Saturday to track down the precise source of the polonium 210 that was used in the murder of Litvinenko.
As British police drew up a list of witnesses for questioning over the death, experts warned that thefts from poorly protected nuclear facilities in the former Soviet Union were a major problem.
A senior source at the International Atomic Energy Agency (IAEA), said he had no doubt that the killing of Litvinenko was an "organized operation" which bore all the hallmarks of a foreign intelligence agency.
Theories that the death may have involved some form of state sponsorship were being investigated by MI5 and MI6 (British intelligence and counter intelligence) who are investigating the possibility that foreign agents may have been behind the death of Litvinenko.
A senior British security source said they were providing the police with material on "hostile intelligence agencies" operating in the UK, including those from Russia.
"Russia has never really decreased their activity in the UK from the end of the Cold War," he said.
More than anything, the death of the London-based former KGB spy has placed Russia's still thriving trade in radioactive material under scrutiny.
One of the few figures available, a database compiled by researchers at Stanford University in the US, revealed that about 40kg of weapons-usable uranium and plutonium were stolen from poorly protected nuclear facilities in the former Soviet Union between 1991 and 2002.
Although the IAEA has no confirmation of polonium finding its way in to the underground trade, there have been several unconfirmed reports of thefts.
In 1993 the Bulletin of Atomic Scientists reported that 10kg of polonium had disappeared from the Sarov, which produces the rare radioactive material and is described as Russia's own version of Los Alamos, the US government's nuclear research base in New Mexico.
Globally, there have been more than 300 cases during the past four years where individuals have been caught trying to smuggle radioactive material. Last year there were 103 confirmed incidents of trafficking and other unauthorized activities involving radioactive materials, many involving Russia.
A humanoid robot that won a half-marathon race for robots in Beijing on Sunday ran faster than the human world record in a show of China’s technological leaps. The winner from Honor, a Chinese smartphone maker, completed the 21km race in 50 minutes and 26 seconds, said a WeChat post by the Beijing Economic-Technological Development Area, also known as Beijing E-Town, where the race began. That was faster than the human world record holder, Ugandan Jacob Kiplimo, who finished the same distance in about 57 minutes in March at the Lisbon road race. The performance by the robot marked a significant step forward
Four contenders are squaring up to succeed Antonio Guterres as secretary-general of the UN, which faces unprecedented global instability, wars and its own crushing budget crisis. Chile’s Michelle Bachelet, Argentina’s Rafael Grossi, Costa Rica’s Rebeca Grynspan and Senegal’s Macky Sall are each to face grillings by 193 member states and non-governmental organizations for three hours today and tomorrow. It is only the second time the UN has held a public question-and-answer, a format created in 2016 to boost transparency. Ultimately the five permanent members of the UN’s top body, the Security Council, hold the power, wielding vetoes over who leads the
South Korea’s air force yesterday apologized for a 2021 midair collision involving two fighter jets, a day after auditors said the pilots were taking selfies and filming during the flight and held them responsible for the accident. “We sincerely apologize to the public for the concern caused by the accident that occurred in 2021,” an air force spokesman told a news conference, adding that one of the pilots involved had been suspended from flying duties, received severe disciplinary action and has since left the military. The apology followed a report released on Wednesday by the South Korean Board of Audit and Inspection,
An earthquake registering a preliminary magnitude of 7.7 off northern Japan on Monday prompted a short-lived tsunami alert and the advisory of a higher risk of a possible mega-quake for coastal areas there. The Cabinet Office and the Japan Meteorological Agency said there was a 1% chance for a mega-quake, compared to a 0.1% chance during normal times, in the next week or so following the powerful quake near the Chishima and Japan trenches. Officials said the advisory was not a quake prediction but urged residents in 182 towns along the northeastern coasts to raise their preparedness while continuing their daily lives. Prime
