Millions of birds migrate to Alaska each summer and most have never been to Japan. Many other seabirds and sea ducks stay in Alaska year-round. For some birds like pintails, only a very small number of them may winter in Japan and then migrate to Alaska. Of the relatively few Alaska birds that may have been exposed to radiation in Japan, the likelihood of a bird living and migrating to Alaska is much less if the exposure was high. If a bird is exposed and healthy enough to migrate, much of the radiation will be eliminated by the time it gets to Alaska. We believe that there is very little chance that you will come across a bird with radiation from Japan’s nuclear accident.
