It reads like something out of a Japanese horror film from the 1960s. After the nuclear accident at Japan’s Fukushima nuclear plant, scientists have found mutations in three generations of butterflies after the exposure to the radiation. They include smaller wings and damaged eyes and affect over ten percent of just that one species — suggesting possible damage to other species exposed in the area.
The abnormalities were found in 12 percent of pale grass blue butterflies that were exposed to nuclear fallout. After three generations the mutations have continued in the species even with mating with unaffected butterflies.
Scientists say that at least one worker is believed to have died as a result of exposure and it may take decades to take a full account of the human toll on workers and citizens in the fallout.
