Novel Sr analysis of environmental samples by Ion-Laser InterAction Mass Spectrometry.

The sensitive analysis of Sr with accelerator mass spectrometry (AMS) was developed to advance environmental radiology. One advantage of AMS is the ability to analyze environmental samples with Sr/Sr atomic ratios of 10 in following a simple chemical separation. Three different IAEA samples with known Sr concentrations (moss-soil, animal bone, Syrian soil: 1 g each) were analyzed to assess the validity of the chemical separation and the AMS measurement.

Use of thermal treatment with CaCl and CaO to remove Cs in the soil collected from the area near the Fukushima Daiichi Nuclear Power Plant.

A massive amount of soils and inflammable materials of plants etc. contaminated by radiocesium are generated from decontamination work in the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident affected area. In present study, the removal experiments of Cs in a soil collected from the FDNPP accident affected area were carried out in a lab-scale electrical heating horizontal furnace through thermal treatment with CaCl addition over a temperature of 900 - 1300 °C.

Reconstruction of anthropogenic I temporal variation in the Japan Sea using a coral core sample.

The anthropogenic long-lived radionuclide I is receiving increased attraction as a new oceanic tracer in addition to usage as a fingerprint of radionuclide contamination of the marine environment. To demonstrate the robustness of I as an oceanic tracer in the Northwest Pacific area, specifically in the Japan Sea, the input history of I to surface seawater was reconstructed using a hermatypic coral core sample from Iki Island in the Tsushima strait. Iodine isotopes in each annual band were measured using AMS and ICP-MS after appropriate pre-treatments of small amounts of coral powder.

Vaporization Mechanisms of Water-Insoluble Cs in Ash During Thermal Treatment with Calcium Chloride Addition.

The vaporization mechanisms of water-insoluble Cs in raw ash and Cs-doped ash during thermal treatment with CaCl addition was systematically examined in a lab-scale electrical heating furnace over a temperature range of 500-1500 °C. The results indicate that the water-insoluble Cs in the ash was associated with aluminosilicate as pollucite. Addition of 10% CaCl caused the maximum vaporization ratio of Cs in the raw ash to reach approximately 80% at temperatures higher than 1200 °C, whereas approximately 95% of Cs was vaporized at temperatures higher than 1300 °C when 30% CaCl was added.

Depth profile and mobility of (129)I and (137)Cs in soil originating from the Fukushima Dai-ichi Nuclear Power Plant accident.

The (129)I derived from the FDNPP accident were clearly identified near the surface and showed a trend of rapid decrease with depth. The FDNPP (129)I and (137)Cs was 51.6 ± 1.

Role of endoscopic ultrasonography in the diagnosis of early esophageal carcinoma.

Endoscopic ultrasonography (EUS) for the diagnosis and staging of early esophageal carcinoma is discussed. Based on the nine-layered structure of esophageal wall, which is in good correspondence with histological layers, depth of carcinoma invasion can be investigated. Ultrasound endoscopes and probes are used for the examination.
