Visited Iidatemura Fukushima to research how radiation affect swallows. Atmospheric dose was 4~5μSv/h at average, the highest reading was 8μSv/h on the ground. Rice fields were abandoned, all the villagers evacuated, we found only a few swallows.
It is not only swallow, we couldn’t find other summer birds such as Narcissus Flycatcher or blue-and-white flycatcher either. It reminded me of “Silent Spring” by Rachel Louise Carson. Forest of no chirp.
