Fukushima News 1/19/14: Highly Radioactive Water Leak Continues;Protests Grow In Japan
16
January, 2014
A
study published in the Elsevier journal Anthropocene late
last year has revealed that many of the rivers, streams and other
waterways located throughout coastal Japan have inadvertently become
delivery systems for transporting radioactive waste directly from the
stricken Fukushima Daiichi nuclear power facility into the Pacific
Ocean.
Researchers from both France and Japan discovered this after conducting a thorough sediment and soil erosion analysis, which revealed the presence of cesium-137, cesium-134 and even radioactive silver in the runoff from coastal rivers. A total of 2,200 soil samples were collected as part of the study, which was originally designed to look at the normal biogeochemical cycles and dispersion of contaminants via rivers and waterways.
Since it is already known that rivers play a functional role in cleansing the natural environment of toxins, a team of scientists from the Laboratory for Climate Sciences and the Environment in France and the Center for Research in Isotopes and Environmental Dynamics in Japan decided to look at how this process works with respect to radiation distribution.
With Fukushima radiation as the source indicator, the team looked for the presence of radioactive isotopes in soil samples collected all along the coastal regions of Japan. By tracking radiation in this way, the team was able to monitor from where the soil and sediment came to gain a better understanding of the transport patterns of particulate matter -- and what they found is telling.
Based on the behaviors of the catchments observed, as well as their relation to the rivers that connect them to nearby mountain ranges, the team determined that many coastal rivers in Japan are a constant source of Fukushima radiation that ends up flowing directly into the Pacific Ocean. Early speculation that radioactive isotopes were probably concentrating in the upper layer of nearby soils also proved to be true.
"Our findings show that [the] Fukushima accident produced original tracers to monitor particle-borne transfers across the affected area shortly after the catastrophe," wrote the authors of the study in their abstract. "We thereby suggest that coastal rivers have become a perennial supply of contaminated sediment to the Pacific Ocean."

Contaminated rivers also sending deadly radiation into lakes, water reservoirs
But
it is not just the Pacific Ocean that is suffering as a result of
constant contamination from Fukushima. A similar study published
earlier in the year in the Journal
of Environmental Radioactivity found
that irrigation waters, paddy fields and lakes are all being poisoned
by the runoff from Fukushima.
After collecting soil samples from two small rivers located in the mountainous region of Fukushima Prefecture, scientists from the Japan-based Institute for Environmental Sciences learned that aerial deposits of nuclear contamination are occurring all across the region, and especially in the top layers of soil found in catchments.
"Our results are extremely important to quantitative assessment of the migration of radiocesium and decontamination of radiocesium in the watersheds impacted by fallout from the accident," concluded the authors about their findings.
Accumulation of radioactive cesium has also been identified in over 20 woody plant species tested in Abiko, which is located some 125 miles southwest of Fukushima and just to the northeast of Tokyo. Researchers from the Central Research Institute of Electric Power Industry, or CRIEPI, found that the leaves of both coniferous and deciduous tree species had become contaminated as a result of radioactive rainfall.
"Further and continuous investigations are necessary to determine how long and how much radiocesium accumulates in the canopy and under the woody plants," the researchers wrote.

Water
leak found inside Fukushima reactor building
NHK,
18
January, 2014
The
operator of the crippled Fukushima Daiichi nuclear power plant says
it has found water pouring into a drain inside the number 3 reactor
building.
Tokyo Electric Power Company says it is yet to determine where the water comes from, or how much radioactive material it contains.
The company said that the water leak was spotted on the first floor of the reactor building on Saturday by a camera installed on a remote-controlled robot used for removing rubbles. It said that the water flow was about 30-centimeters wide and constant.

TEPCO added that the water is likely flowing
toward the building's basement where a large amount of radioactive
water has accumulated.
TEPCO says that inside the reactor
building there is water for cooling melted fuel and water in the
spent fuel storage pool. It says rain water may have entered the
damaged building.
TEPCO is trying to find out the source of
the leaking water by analyzing footage taken by the camera, as
radiation levels are too high for workers to approach the site.
