“Visualize” invisible radioactive hotspots in three dimensions —Understanding the distribution of radioactive substances, and developing technology to help restore the environment of Fukushima—

Inside the Fukushima Daiichi Nuclear Power Station of Tokyo Power Electric Holdings Inc., there is still a high dose rate, and an environment that does not allow entry by workers.
Collaborative Laboratories for Advanced Decommissioning Science (CLADS) has developed technology effective for reducing the radiation dose in decommissioning work at the Fukushima Daiichi Nuclear Power Station.
The newly developed system is based on the Compton camera, and can visualize the distribution of radioactive substances in three dimensions.

The 99th element einsteinium opens the way to the science of heavy elements

Einsteinium is a little-known element.
This is an artificial element named after one of the world’s most prominent physicists, Albert Einstein. Today, einsteinium is the heaviest element available to mankind for use in physical and chemical experiments. This element is produced in minute quantities – about one microgram or one-millionth of the weight of one gram, using neutron capture process in isotope-production reactors.

For the first time in Japan, JAEA is conducting experiment using einsteinium.

Recovering Satoyama in Fukushima - New Technique to Suppress Migration of Radioactive Cesium from Forests -

Satoyama, a border zone between mountain foothills and arable flat land, is the surrounding natural land that has supported the traditional life of rural villages in Japan.
Such satoyama zones used to be a place of residential life in Fukushima Prefecture, where about 70% of the prefectural area is covered with forest.
But in forests, radioactive cesium tends to accumulate in the leaf mold layer that lies between the defoliated-leaf layer and the soil layer. When the radioactive cesium is eluted to water, it causes contamination of forest plants. Furthermore, in sloping lands, the cesium can slowly move downhill by the action of rainwater, resulting in recontamination of residential areas that had been previously decontaminated.
Since immediately after the nuclear accident, JAEA has continuously been working on radiation monitoring as well as research and development of decontamination methods. JAEA is now conducting a demonstration of a new technique for suppressing migration of radioactive cesium, jointly with Ibaraki University and Kumagai Gumi.

Aomori Research and Development Center ~Mutsu district~

Mutsu city in Aomori Prefecture is located on the Shimokita Peninsula, facing Mutsu Bay and the Tsugaru Strait, at the northernmost end of the island of Honshu. The Sekine Facility and Ominato Facility of the Aomori Research and Development Center are located here.

The Sekine Facility was the port where maintenance and inspection of the nuclear-powered ship "Mutsu" were implemented and, after completing its last experimental voyage, the ship returned. Today, the nuclear reactor facility of the ship is being decommissioned here.

The Ominato Facility was started as the port which the "Mutsu" was first brought into after its hull was completed.
At present, using a system called accelerator mass spectrometer or “AMS” which can measure infinitesimal amount of radionuclide, etc. existing in the global environment with the accuracy of the highest level in the world, analysis of samples in a broad-ranging areas such as geoscience, life science and archaeology, as well as development of such analysis technology, is carried out.

Director Yabuuchi with the experience as the “Mutsu” crewmember introduces these facilities.

Without blood drawing with a prick ~Towards development of a palm-sized non-invasive blood sugar sensor~A Thread of “Light” to People with Diabetes

The number of diabetic patients is said to be 400 million in the world, and in Japan the number increases every year. Under such circumstance, JAEA has successfully developed a non-invasive type (without damaging living body) blood sugar sensor.
If this sensor, enabling blood sugar test without painful blood sampling, becomes widely used, the burden of patients as well as that of medical staff engaged in blood sampling and data input will be alleviated, and time taken for treatment will be reduced.
Also, if the non-invasive type blood sugar sensor is placed in city halls, libraries and other public and private organizations and thus become conveniently available to people like the blood pressure measuring apparatus, it will help daily prevention of diabetes.
