The Chronicle Editorial LiveJournalists tossed a little chemistry at readers today:
There is no evidence that Putin or anyone in the Kremlin had Litvinenko killed. The radioactive material, polonium-120, must be produced by a nuclear reactor or research lab, but could have come from anywhere and been acquired on the black market.
Actually, as Matt Bramanti suggested in an email earlier, Polonium 120 might well have been created by those mad-scientist Editorial LiveJournalists/Leftover Physicists down at 801 Texas Avenue, but it was the radioactive Polonium-210 isotope that killed former Russian spy Alexander Litvinenko.
