Isotopes of polonium Polonium has 33 known isotopesall of which are radioactive. They have atomic masses that range from to u. It was Curie's hope that naming the element after her native land would publicize its lack of independence.
Alexander Litvinenko Alexander Litvinenko was a former officer of the Russian Federal Security service who escaped prosecution in Russia and received political asylum in the United Kingdom. In his books, Blowing up Russia: He alleged that a key element of the FSB's strategy was to frighten Russians by bombing apartment buildings in Moscow and other Russian cities.
Kovtun is now a businessman. Litvinenko had also had lunch at Itsua sushi restaurant on Piccadilly in London, with an Italian officer and " nuclear expert", Mario Scaramellato whom he reportedly made allegations regarding Romano Prodi 's connections with the KGB. He passed Litvinenko papers supposedly concerning her fate.
On 20 November, it was reported that Scaramella had gone into hiding and feared for his life. At one point, he could not walk without assistance.
As the pain intensified, Litvinenko asked his wife to call an ambulance for assistance. Surrounded by friends, Litvinenko became physically weak, and spent periods unconscious. A photograph was taken of Litvinenko on his deathbed and released to the public. Scientists at AWE tested for radioactive poison using gamma spectroscopy.
No discernible gamma rays were initially detected; however, a small gamma ray spike was noticed at an energy of kilo-electron volts keVbarely visible above the background. The BBC reported that by coincidence another scientist, who had worked on Britain's early atomic bomb programme decades before, happened to overhear a discussion about the small spike and recognised it as the gamma ray signal from the radioactive decay of polonium, which was a critical component of early nuclear bombs.
On the evening of 22 November, shortly before his death, his doctors were informed the poison was likely to be polonium Further tests on a larger urine sample using spectroscopy designed to detect alpha particles confirmed the result the following day.
This explained why tests conducted by doctors and Scotland Yard at the hospital with Geiger counters were negative. Both gamma rays and alpha particles are classified as ionizing radiation which can cause radiation damage.
An alpha-emitting substance can cause significant damage only if ingested or inhaled, acting on living cells like a short-range weapon. British and US government officials said the use of Po as a poison had never been documented before, and it was probably the first time anyone had been tested for the presence of Po in their body.
The poison was in Litvinenko's cup of tea. It was reported that early tests appeared to confirm the presence of the poison.
Litvinenko attributed his initial survival to his cardiovascular fitness and swift medical treatment. It was later suggested a radioactive isotope of thallium might have been used to poison Litvinenko. Hours before his death, three unidentified circular-shaped objects were found in his stomach via an X-ray scan.
You may succeed in silencing me but that silence comes at a price. You have shown yourself to be as barbaric and ruthless as your most hostile critics have claimed. You have shown yourself to have no respect for life, liberty or any civilised value. You have shown yourself to be unworthy of your office, to be unworthy of the trust of civilised men and women.
You may succeed in silencing one man but the howl of protest from around the world will reverberate, Mr Putin, in your ears for the rest of your life.
May God forgive you for what you have done, not only to me but to beloved Russia and its people. Litvinenko's movements at relevant times, including when he first became ill and identify people he may have met.
There will also be an extensive examination of CCTV footage. The first attempt took place on 16 Octoberwhen radioactive traces were found in all places visited by the FSB operatives before and after their meeting with Litvinenko. They administered the poison to his tea, but he did not drink it.
Apparently, Lugovoy and Kovtun did not fully realize they were handling a radioactive poison. Journalist Luke Harding described their behaviour as "idiotic, verging on suicidal"; while handling a leaky container, they stored it in their hotel rooms, used ordinary towels to clean up leaks, and eventually disposed of the poison in the toilet.
On 17 October, perhaps realizing they contaminated their rooms, they prematurely checked out, moved to another hotel, and left London the next day.#ARROWFIRE UPDATE: Heavy smoke from the fire in the Santa Fe Dam is impacting the Metro Gold Line and traffic on the freeway and Foothill Blvd.
