Mutant Butterflies found in Fukushima

Fukushima ’caused mutant butterflies’ August 14, 2012 by Shingo Ito

Japan’s pale grass blue butterflies, showing signs of genetic mutation after last year’s Fukushima nuclear accident, according to researchers.
Genetic mutations have been found in three generations of butterflies from near Japan’s crippled Fukushima nuclear plant, scientists said Tuesday, raising fears radiation could affect other species.
Around 12 percent of pale grass blue butterflies that were exposed to nuclear fallout as larvae immediately after the tsunami-sparked disaster had abnormalities, including smaller wings and damaged eyes, researchers said.
The insects were mated in a laboratory well outside the fallout zone and 18 percent of their offspring displayed similar problems, said Joji Otaki, associate professor at Ryukyu University in Okinawa, southwestern Japan.
That figure rose to 34 percent in the third generation of butterflies, he said, even though one parent from each coupling was from an unaffected population.
The researchers also collected another 240 butterflies in Fukushima in September last year, six months after the disaster. Abnormalities were recorded in 52 percent of their offspring, which was “a dominantly high ratio”, Otaki told AFP.
Otaki said the high ratio could result from both external and internal exposure to radiation from the atmosphere and in contaminated foodstuffs.
The results of the study were published in Scientific Reports, an online research journal from the publishers of Nature. Otaki later carried out a comparison test in Okinawa exposing unaffected butterflies to low levels of radiation, with the results showing similar rates of abnormality, he said. “We have reached the firm conclusion that radiation released from the Fukushima Daiichi plant damaged the genes of the butterflies,” Otaki said.
The quake-sparked tsunami of March 2011 knocked out cooling systems at the Fukushima Daiichi nuclear power plant, causing three reactors to go into meltdown in the world’s worst atomic disaster for 25 years.
The findings will raise fears over the long-term effects of the leaks on people who were exposed in the days and weeks after the accident, as radiation spread over a large area and forced thousands to evacuate. There are claims that the effects of nuclear exposure have been observed on successive generations of descendants of people living in Hiroshima and Nagasaki when the US dropped atomic bombs in the final days of World War II.

Flowers Versus Fukushima Snow

Sunflowers melt Fukushima’s nuclear “snow”

FUKUSHIMA, Japan, Aug. 19, 2011 (Reuters) — Sparks from burning strips of paper swirled into the hot summer sky, carrying the names of the dead above a temple in Fukushima where thousands of sunflowers have been planted to help fight the omnipresent radiation.

he Fukushima Daiichi nuclear plant some 50 km away suffered a series of core meltdowns and explosions after the massive March 11 earthquake and tsunami knocked out cooling systems, setting off the world’s worst nuclear accident in 25 years and forcing tens of thousands from their homes.

“It is as if an invisible snow had fallen on Fukushima and continued to fall, covering the area,” said Koyu Abe, chief monk at the Buddhist Joenji temple.

“This snow, which doesn’t melt, brought a long, long winter to Fukushima.”

Some 80,000 people were forced to evacuate from a vast swathe of land around the reactor as engineers battled radiation leaks, hydrogen explosions and overheating fuel rods — and have no idea when, if ever, they can return to homes that have been in their families for generations.

Worse still, radiation spread well outside the mandatory evacuation zone, nestling in “hot spots” and contaminating the ground in what remains a largely agricultural region.

Rice, still a significant staple, has not been planted in many areas. Others face stringent tests and potentially harmful shipping bans after radioactive cesium was found in rice straw.

Excessive radiation levels have also been found in beef, vegetables, milk, seafood and water and, in hot spots more than 100 km from the plant, tea.

In an effort to lift the spirits of area residents as well as lighten the impact of the radiation, Abe began growing and distributing sunflowers and other plants.

“We plant sunflowers, field mustard, amaranthus and cockscomb, which are all believed to absorb radiation,” said the monk.
