Patchy Hair Loss On Seals

Scientists in Alaska are investigating whether seals are being killed by radiation from Japan's crippled Fukushima nuclear plant.

Scores of ring seals have washed up on Alaska's arctic coastline since July either injured or killed by a mysterious disease which biologists first thought was a virus.

But the bleeding lesions on the hind flippers, irritated skin around the nose and eyes and patchy hair loss on the seals' fur coats may have been caused by radiation from the stricken nuclear plant.

Scary.
