BA radiation

By Michael J.W. Stickings

From WaPo:

British authorities investigating the death of former Russian spy Alexander Litvinenko have discovered low levels of radiation on two British Airways jetliners, prompting the airline to ground the planes and issue warnings to as many as 33,000 passengers who traveled in the past month on those aircraft and on a third plane grounded in Moscow, company officials said Wednesday...

The radiation found on the planes is an important new clue for investigators who are trying to solve an extraordinary case that has caused political tensions between London and Moscow. It may help determine where the material that killed Litvinenko, called polonium-210, came from as detectives follow the trail created by the radioactive substance.

Odd. And interesting. And, well, a bit scary. The BBC has more here.
