Japan is bracing itself for the most
dangerous operation at the Fukushima nuclear plant since it was
crippled by a quake and tsunami in March 2011. The company running the
facility plans to move radioactive fuel rods to safe storage. RT's
Alexey Yaroshevsky is in Japan for us. Christina Consolo, Founder and
Host of Nuked Radio, doubts that engineers will be able to pull this off
- given the level of damage at the plant.

Fukushima plant prepared for uranium and plutonium removal
engineers in Japan are preparing to move uranium and plutonium fuel
rods at Fukushima, their most difficult and dangerous task since the
plant's runaway reactors were brought under control two years ago.

IAEA experts inspect seawater checks off Fukushima
experts from the International Atomic Energy Agency have inspected the
procedures for checking radioactivity in seawater off the damaged
Fukushima plant.
David Osborn directs the IAEA Environment
Laboratories in Monaco and Hartmut Nies is the head of the IAEA
Radiometrics Laboratory.
They left Onahama port in Fukushima Prefecture on board a boat for seawater monitoring on Thursday.
plant's operator, the Tokyo Electric Power Company, commissioned the
boat to collect water samples within 20 kilometers of the facility.
inspection took place after Japan's Nuclear Regulation Authority and
the IAEA agreed to cooperate to bolster the credibility of seawater
checks and analysis.
International concern over radioactive
contamination of the sea is growing because of repeated leaks of tainted
water at the plant.
Osborn said methods to collect seawater samples
were appropriate under international standards. He said the IAEA will
continue to cooperate if requested by Japan.
On Friday, the team is scheduled to visit a facility where collected samples are analyzed for levels of radioactive substances.

Large-scale Soviet nuclear tests, dumping of spent fuel and two  scuttled nuclear-powered submarines are a major source of pollution  in the Arctic ocean, a Russian research institute has said.

There are 17,000 containers and 19 vessels holding radioactive waste  submerged in the Kara Sea, as well as 14 nuclear reactors, said  a report passed by Russia to the Norwegian authorities  in 2012, according to Bellona, an environmental group that  acquired a copy of document.

As the Arctic thaws under the influence of global warming,  oceanic currents in the region could strengthen, carrying  the radioactive material to other continents, Alexander Shestakov,  head of the Global Arctic Program at WWF, or World Wildlife Fund,  said.

The sinking of nuclear material and scuttling of ships  used to be widespread practice. Of particular worry now is  the Soviet nuclear submarine, K-27, scuttled in 1981 in the Kara  Sea. The boat, equipped with two nuclear reactors, was filled with bitumen  and concrete before being sunk, according to the Russian Nuclear  Safety Institute, to ensure that it would lie safely on the ocean  floor for 50 years.

That period is nearly up. Last year, speakers at a joint seminar with  Bellona and state nuclear company Rosatom warned that a nuclear  reaction could occur on the K-27.

"Before that, no-one knew about the danger," Igor Kudrik, a nuclear  safety expert at Bellona said.

4170 Bq/Kg of Radioactive Cesium in Crickets in Iitate-mura, Fukushima

A researcher (vice president) at Tokyo University of Agriculture and Technology collected 500 crickets (1 kilogram) in Iitate-mura in Fukushima Prefecture, and found 4,000 becquerels/kg of radioactive cesium. He also tested locusts in different locations in Fukushima, and found radioactive cesium in them.

Bio-concentration at work. No information whether he tested other nuclides like radioactive silver (Ag-110m). Professor Bin Mori of Tokyo University found radioactive silver highly concentrated (1000 times the amount in the environment) in Nephila clavata he caught in Iitate-mura.

From Yomiuri Shinbun (1/12/2012):


A survey conducted by Hajime Fugo, vice president of Tokyo University of Agriculture and Technology (specialty: insect physiology) found over 4,000 becquerels/kg of radioactive cesium in crickets (500 of them that weigh about 1 kilogram) from within the planned evacuation zone 40 kilometers away from Fukushima I Nuclear Power Plant.


In another location, 200 becquerels/kg of radioactive cesium was found from locusts.


The survey was done in October last year. 500 crickets were collected in the northern part of Iitate-mura in Fukushima Prefecture, which is in the planned evacuation zone 40 kilometers from the plant. 2,000 locusts were collected in locations 60 to 80 kilometers from the plant, including Motomiya City (around City Hall), northern part of Sukagawa City, Koori-machi (near Town Hall) and near Inawashiro Lake in Inawashiro-machi.


Average 4,170 becquerels/kg of radioactive cesium was detected from crickets in Iitate-mura, 196 becquerels/kg from locusts in Sukagawa City, 82 becquerels/kg and 75 becquerels/kg from locusts in Koori-machi and Motomiya City respectively.
