Background: Alexander Valterovich Litvinenko (Russian: Aleksandr Val'terovich Litvinenko, IPA: [aljI'ksandr 'valtir@vjItc ljItvjI'njenk@]; 30 August 1962 (Or 4 December 1962 by father's account - 23 November 2006) was a British naturalised Russian defector and former officer of the Russian FSB secret service who specialised in tackling organised crime. According to US diplomats, Litvinenko coined the phrase Mafia state. In November 1998, Litvinenko and several other FSB officers publicly accused their superiors of ordering the assassination of the Russian tycoon and oligarch Boris Berezovsky.
Context: On 1 November 2006, Litvinenko suddenly fell ill. On 3 November, he was admitted to Barnet General Hospital in London. He was then moved to University College Hospital for intensive care. His illness was later attributed to poisoning with radionuclide polonium-210 after the Health Protection Agency found significant amounts of the rare and highly toxic element in his body. In interviews, Litvinenko stated that he met with two former KGB agents early on the day he fell ill - Dmitry Kovtun and Andrei Lugovoy. Though both denied any wrongdoing, a leaked US diplomatic cable revealed that Kovtun had left polonium traces in the house and car he had used in Hamburg. The men also introduced Litvinenko to a tall, thin man of central Asian appearance called 'Vladislav Sokolenko' who Lugovoy said was a business partner. Lugovoy is also a former bodyguard of Russian ex-Acting Prime minister Yegor Gaidar (who also suffered from a mysterious illness in November 2006). Later, Litvinenko had lunch at Itsu, a sushi restaurant in Piccadilly in London, with an Italian acquaintance and nuclear waste expert, Mario Scaramella, to whom he made the allegations regarding Italy's Prime Minister Romano Prodi. Scaramella, attached to the Mitrokhin Commission investigating KGB penetration of Italian politics, claimed to have information on the assassination of Anna Politkovskaya, 48, a journalist who was killed at her Moscow apartment building in October 2006. Marina Litvinenko, his widow, accused Moscow of orchestrating the murder. Though she believes the order did not come from Putin himself, she does believe it was done at the behest of the authorities, and announced that she will refuse to provide evidence to any Russian investigation out of fear that it would be misused or misrepresented. On a court hearing in London in 2015, a Scotland Yard lawyer concluded that "the evidence suggests that the only credible explanation is in one way or another the Russian state is involved in Litvinenko's murder".
Question: How was he poisoned?
Answer: His illness was later attributed to poisoning with radionuclide polonium-210

Background: Queens of the Stone Age are an American rock band formed in 1996 in Palm Desert, California. The band's line-up includes founder Josh Homme (lead vocals, guitar, piano), alongside band members Troy Van Leeuwen (guitar, lap steel, keyboard, percussion, backing vocals), Michael Shuman (bass guitar, keyboard, backing vocals), Dean Fertita (keyboards, guitar, percussion, backing vocals), and Jon Theodore (drums, percussion). Formed after the dissolution of Homme's previous band, Kyuss, Queens of the Stone Age developed a style of riff-oriented, heavy rock music. Their sound has since evolved to incorporate a variety of different styles and influences, including working with ZZ Top member Billy Gibbons, Nirvana drummer and Foo Fighters frontman Dave Grohl, and Screaming Trees frontman Mark Lanegan who has been a steady contributor to the band.
Context: Foo Fighters frontman and former Nirvana drummer, Dave Grohl, joined in late 2001 to record drums for their third album. Songs for the Deaf was released in August 2002, again featuring Lanegan, along with former A Perfect Circle guitarist Troy Van Leeuwen to the touring line-up following the album's release. Also featured on Songs for the Deaf for the final track "Mosquito Song" were former A Perfect Circle bassist Paz Lenchantin on viola and piano, and Dean Ween on guitar. This record was supposed to sound bizarre--like lightning in a bottle. We also were extremely fucked up. It even sounds that way to me, like a crazy person. The radio interludes are supposed to be like the drive from L.A. to Joshua Tree, a drive that makes you feel like you're letting go--more David Lynch with every mile. Songs for the Deaf was a critical hit and was certified gold in 2003, with sales of over 900,000. The singles "No One Knows" and "Go with the Flow" became hits on radio and MTV, with the former just outside the Billboard Top 40. "No One Knows" and "Go with the Flow" were also featured on the first iterations of the popular video games Guitar Hero and Rock Band (respectively). The Songs for the Deaf tour culminated in a string of headline dates in Australia in January 2004. Grohl returned to his other projects and was replaced on the European leg of the tour by former Danzig drummer Joey Castillo, who joined the band full-time. After the tour, Homme fired Oliveri, as he was convinced that Oliveri had been physically abusive to his girlfriend: "A couple years ago, I spoke to Nick about a rumor I heard. I said, 'If I ever find out that this is true, I can't know you, man.'" Homme considered breaking up the band after firing Oliveri, but found a new determination to continue. Oliveri countered in the press that the band had been "poisoned by hunger for power" and that without him, they were "Queens Lite." He later softened his opinion and said: "My relationship with Josh is good. The new Queens record kicks ass." The two reportedly are still friends and as of October 2006, Oliveri was interested in rejoining the band. Oliveri later contributed to a Queens of the Stone Age for the first time in nine years, contributing backing vocals to the band's sixth album, ...Like Clockwork.
