– Researchers hurt at Ibaraki nuclear facility (Japan Times, Kyodo News, May 26, 2013):

At least six researchers suffered internal radiation exposure when an experiment involving elementary particles went awry and up to 24 more are feared to have been similarly exposed, the Japan Atomic Energy Agency said Saturday.

Radioactive substances leaked following the accident Thursday in the Hadron Experimental Facility of the Japan Proton Accelerator Research Complex (J-PARC) in Tokai, Ibaraki Prefecture, the government-affiliated agency reported.

Officials from the Ibaraki Prefectural Government raided the complex Saturday afternoon to investigate the delay in reporting the incident. A malfunction occurred at 11:55 a.m. Thursday during an experiment to produce elementary particles by aiming a proton beam at a target made of gold, the agency said.

An alarm went off shortly afterward and the experiment was halted. But a researcher in charge of the equipment restarted it at 12:08 p.m., despite not having pinpointed the cause of the alarm, sources familiar with the investigation said.

Radioactive Japan: Miyagi, Tochigi, Ibaraki, Chiba To Have Final Disposal Sites For Highly Radioactive Ashes

– #Radioactive Japan: Miyagi, Tochigi, Ibaraki, Chiba to Have Final Disposal Sites for Highly Radioactive Ashes from Garbage Incineration, Sludge

Goshi Hosono’s Ministry of the Environment is on the sudden offensive against citizens and residents of Kanto and Tohoku, again.

According to the Yomiuri Shinbun article, the Ministry of the Environment is already talking with the officials in the municipalities in three prefectures to built final disposal sites in their cities and towns.

As the wide-area disposal of disaster debris winds down as it is now widely revealed that there is simply not enough debris to widely distribute, Mr. Hosono looks desperate to do something so that he can claim he has made people “share the pain”.

From Yomiuri Shinbun (8/21/2012):

– 6,264.74 Bq/Kg from house dust in Ibaraki (Fukushima Diary, Dec. 14, 2011):

Journalist Kinoshita Kota conducted measurements for house dust in Tokyo, Chiba, Ibaraki, and Aichi.

As a result, no wonder, it turned out that cesium has gotten into the houses already.

Radiation Hot Spots All Around Elementary School In Ibaraki (30 km From Tokyo), 120,000 Bq/Kg of Cesium In Soil Near Entrance

– 120,000 Bq/Kg from elementary school in Ibaraki (Fukushima Diary, Nov. 5, 2011):

A local NPO group “Save children from radiation” measured 120,000 Bq/kg of Cs in the soil near entrance of Ryugasaki Kubodai elementary school.
Beside the pool,they also measured 11,720~19,050 Bq/Kg from soil of 4 locations.

In the area of the elementary school,at 1m high from the ground,2 micro Sv/h at 2 locations,1 micro Sv/h at 14 locations.
In mid october,they decontaminated the area but still they measure 1 micro Sv/h at 6 locations.

In this city,they also measure over 0.23 micro Sv/h at 178 locations.

Obviously,evacuation is the better way to survive than decontamination.

– Radioactive materials found off Miyagi and Ibaraki (NHK, May 28, 2011):

Japan’s science ministry has detected extraordinarily high levels of radioactive cesium in seafloor samples collected off Miyagi and Ibaraki Prefectures.

Experts say monitoring should be stepped up over a larger area to determine how fish and shell fish are being affected.
