Vertical distribution of radioactive cesium-rich microparticles in forest soil of Hamadori area, Fukushima Prefecture

Autor: Takahiro Tatsuno, Hiromichi Waki, Naoto Nihei, Nobuhito Ohte

A lot of radionuclides were scattered after the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident. Previous studies showed that there were FDNPP-derived radioactive cesium-rich microparticles (CsMPs) with the size of a few μm in the soil and ri

Radioactive cesium-rich microparticles (CsMPs) derived from the Fukushima Daiichi Nnuclear Power Plant accident were detected from soils and river water around Fukushima Prefecture, Japan. Because CsMPs are insoluble and rich in radioactive cesium (R

Publikováno v: Radiation protection dosimetry. 198(13-15)

Cesium-rich microparticles (CsMPs) with high cesium-137 (137Cs) concentrations were released and deposited in surface soil after the Fukushima Daiichi Nuclear Power Plant accident. Radioactive materials on the soil surface layer enter rivers owing to

Vertical migration of cesium in weathered granite soil under flowing water condition depending on Cs concentration and states of dissolved organic matter

Autor: Takahiro Tatsuno, Shoichiro Hamamoto, Naoto Nihei, Taku Nishimura

Publikováno v: Journal of Environmental Management. 306:114409

After the accident at the Fukushima Daiichi nuclear power plant in Japan, the migration of radioactive cesium (Cs) in soils has become a crucial issue since this can negatively affect human health and the surrounding environment. Dissolved organic ma

Publikováno v: Anthropocene. 22:40-50

Radionuclides released by the accident at the Fukushima Daiichi Nuclear Power Plant included 137Cs (Cesium-137) and 134Cs (Cesium-134), which were deposited on land as a result of fallout and concentrated in the uppermost 2–5 cm of the soil. In thi

Effects of the dissolved organic matter on Cs transport in the weathered granite soil

Autor: Takahiro Tatsuno, Shoichiro Hamamoto, Naoto Nihei, Taku Nishimura

Publikováno v: Journal of environmental management. 254

It is important to understand the migration of Cesium (Cs) in soils, particularly after the nuclear power plant accident at Fukushima Dai-ichi, Japan. Dissolved organic matter (DOM) is one of factors affecting the migration of Cs in soils under flowi

Hybrid Friction Stir Welding of Carbon Steel

Autor: Manabu Tanaka, Hidetoshi Fujii, Takahiro Tatsuno, Kazuhiro Nakata, Takuya Tsumura

Publikováno v: Materials Science Forum. :393-396

A new welding technique called hybrid FSW was developed to decrease the tool load and the defects during the FSW of high melting point materials. This method consists of FSW and a laser for preheating ahead of the tool. The hybrid FSW enables the pro
