The UK’s Health Protection Agency has a follow-up on their monitoring of people and places potentially contaminated with the extremely dangerous alpha-emitter, Polonium-210, the weapon used to kill Russian dissident Alexander Litvinenko (see our posts here and here about Polonium-210, and here and here about the murder). Their spin is that tests “so far” show…

More on the Polonium-210 poisoning

We mostly like being right, but we sometimes wish we weren’t. A few days ago we concluded a post) on some scientific background about Polonium-210 by saying this assassination could also become a public health problem. That now seems to be the case, as a trail of radiation is being found in the victim’s wake.…

Polonium-210, Part II.

[This is Part II of our explanation of some of the science behind the Polonium-210 poisoning case of Alexander Litvinenko. Part I. is here.] In Part I. we sketched the physical background to understand radioisotopes like Polonium-210, the agent in the Litvinenko poisoning, but have yet to explain its connection to the biology. That’s today’s…
