British health authorities say 10 people affected by poison that killed ex-Soviet spy

Ten people have shown signs of low-level exposure to polonium-210, the rare radioactive element that killed one-time Russian intelligence agent Alexander Litvinenko - but they are unlikely to get ill, British

health authorities said Thursday.

The Health Protection Agency said those affected had not suffered enough exposure to cause illness in the short term, and the long-term risk of illness is very small. (AP)
