Publikováno v: Heliyon, Vol 9, Iss 4, Pp e14153- (2023)

The long-lived U isotopes, 233U and 236U, have been used increasingly in recent years as marine circulation tracers and for identifying sources of uranium contamination in the environment. The sedimentation histories of these two U isotopes in combin

DISTRIBUTION OF IODINE-127 IN MARINE ORGANISMS FROM COASTAL WATERS AROUND AOMORI, JAPAN

Autor: Shoko Imai, Kensaku Matsushita, Yuichi Takaku, Yoshio Ishikawa

Publikováno v: Radiation Protection Dosimetry. 198:1066-1070

We measured the concentrations and determined the distribution of the stable isotope 127I in the marine organisms. Marine fish were collected from the Pacific Ocean near Aomori, Japan. The mean 127I concentrations in the muscle of marine fish ranged

IODINE ABSORPTION BY APPLE LEAF SURFACES

Autor: Masumi Yanai, Hitoshi Kawabata, Yuichi Takaku

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

Apple is an important agricultural product in Aomori Prefecture, Japan, where the first commercial nuclear fuel reprocessing plant is currently under construction. As the behavior of radioiodine deposited on the surface of apple leaves is not well kn

INVESTIGATION OF SHORT-TERM CHEMICAL CHANGE IN STABLE RUTHENIUM ADDED TO RAINWATER THROUGH X-RAY ABSORPTION FINE STRUCTURE ANALYSIS

Autor: Yusuke Unno, Akira Takeda, Yuichi Takaku

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

Radioactive ruthenium may be accidentally released from spent nuclear fuel reprocessing plants to the surrounding environment. To obtain basic information regarding the effect of radioactive ruthenium on the environment, we investigated changes in th

TRANSFER OF CESIUM AND IODINE FROM THE SURFACE TO THE INTERIOR OF APPLE FRUIT

Autor: Hitoshi Kawabata, Masumi Yanai, Yuichi Takaku, Shun’ichi Hisamatsu

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

We investigated the transfer of stable Cs + and I− applied as droplets directly on the fruit surface of 3-y-old plumleaf crab apple trees to the fruit interior at different developmental stages. The proportions of Cs and I transferred to the fruit

SOIL-SOIL SOLUTION DISTRIBUTION COEFFICIENT OF RADIOIODINE IN SURFACE SOILS AROUND SPENT NUCLEAR FUEL REPROCESSING PLANT IN ROKKASHO, JAPAN

Autor: Akira Takeda, Yusuke Unno, Hirofumi Tsukada, Yuichi Takaku, Shunichi Hisamatsu

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

The soil-soil solution distribution coefficient (Kd) of radioiodine in soil samples with various total carbon (TC) contents was measured in a batch sorption experiment using 125I tracer spiked as I−. The log values of Kd−125I and TC concentration
