Fukushima nuclear disaster will impact forests, rivers and estuaries for
hundreds of years, warns Greenpeace report
Tokyo, 4 March 2016 - The
environmental impacts of the Fukushima Daiichi nuclear disaster will last
decades to centuries, warns a new Greenpeace Japan report. Man-made, long-lived
radioactive elements are absorbed into the living tissues of plants and animals
and recycled through food webs, and carried downstream to the Pacific Ocean by
typhoons, snowmelt, and flooding.
“The government’s massive
decontamination program will have almost no impact on reducing the ecological
threat from the enormous amount of radiation from the Fukushima nuclear
disaster. Already, over 9 million cubic metres of nuclear waste are scattered
over at least 113,000 locations across Fukushima prefecture,” said Kendra
Ulrich, Senior Nuclear Campaigner at Greenpeace Japan.
“The Abe
government is perpetuating a myth that five years after the start of the nuclear
accident the situation is returning to normal. The evidence exposes this as
political rhetoric, not scientific fact. And unfortunately for the victims, this
means they are being told it is safe to return to environments where radiation
levels are often still too high and are surrounded by heavy
contamination.”
The report is based on a large body of independent
scientific research in impacted areas in the Fukushima region, as well as
investigations by Greenpeace radiation specialists over the past five years. It
exposes deeply flawed assumptions by the International Atomic Energy
Agency and the Abe government in terms of both decontamination and ecosystem
risks. It further draws on research on the environmental impact of the 1986
Chernobyl nuclear catastrophe as an indication of the potential future for
contaminated areas in Japan.
The environmental impacts are already
becoming apparent, with studies showing:
- High radiation concentrations in new leaves, and
at least in the case of cedar, in pollen;
- apparent increases in growth mutations of fir
trees with rising radiation levels;
- heritable mutations in pale blue grass butterfly
populations and DNA-damaged worms in highly contaminated areas, as well as
apparent reduced fertility in barn swallows;
- decreases in the abundance of 57 bird species
with higher radiation levels over a four year study; and
- high levels of caesium contamination in
commercially important freshwater fish; and radiological contamination of one
of the most important ecosystems – coastal estuaries.
“There is no end
in sight for communities in Fukushima - nearly 100,000 people haven’t returned
home and many won’t be able to. The Japanese government should put its citizens
first, the majority of who reject the restart of nuclear reactors. Many
are demanding the only safe and clean options that can meet Japan’s needs -
renewable energy,” said Ulrich.
Greenpeace has conducted 25 radiological
investigations in Fukushima since March 2011. In 2015, it focused on the
contamination of forested mountains in Iitate district, northwest of the
Fukushima Daiichi nuclear power plant. Both Greenpeace and independent research
have shown the movement of radioactivity from contaminated mountain watersheds,
which can then enter coastal ecosystems. The Abukuma, one of Japan’s largest
rivers which flows largely through Fukushima prefecture, is projected to
discharge 111 TBq of 137Cs and 44 TBq of 134Cs, in the 100 years after the
accident.
Currently, a Greenpeace Japan led research team is
investigating the radiation contamination of the ocean and river estuary
sediments along the coastline of Fukushima. The underwater investigation is
being conducted from a Japanese research vessel, supported by the Greenpeace
ship, the Rainbow Warrior. The Fukushima disaster is the single largest release
of radioactivity into the ocean and one of only two Level 7 nuclear disasters in
world history - the other being Chernobyl.
