Subject of Study

○	Alpha-decay properties of neutron-deficient americium isotopes (アメリシウム同位体($_{95}$Am)を含む中性子不足アクチノイド核種領域には，半減期が数分と予測されているにもかかわらず，未発見の核種や，その存在が確認されているものの壊変特性データの不明確な核種が多数ある．図1に，中性子不足アクチノイド核種領域を含むトリウムから112番元素までの核図表を示す．この核種領域の研究が困難な理由として，第一に，陽子ドリップライン近傍では，中性子の分離エネルギーが高くなり，蒸発残留核が生成しにくい．また，核分裂過程が強くなるために，蒸発残留核が生成したとしても残存する確率が低い．第二に，これら核種の主要な壊変形式が，電子捕獲(Electron Capture : EC)壊変であると予想され，EC壊変に伴う特性X線を検出する必要があり，バックグラウンドとの競争で検出限界が高くなる．この領域での未知核種の探索とその壊変特性に関する研究は，中性子が不足している原子核(陽子ドリップライン近傍核)の安定性や核構造を理解する上で非常に興味深い．主要な壊変形式は，EC壊変であるが，その分岐比の小さいα壊変特性は，超アクチノイド元素の原子核質量値を決定する上で重要な役割を果たす．たとえば，超アクチノイド核種の$^{255, 256}$Db，$^{259}$Sg，$^{261}$Bh，$^{266}$Mt，$^{253}$Rfは，比較的早い時期から米国，ドイツ，ロシアをはじめとする重元素合成実験(hot fusionやcold fusion)で合成されてきた．通常，それら核種同定は，α壊変連鎖を逐次観測し，α娘核までの到達によって行われている．そのα壊変連鎖の末端を，さらに下っていくと精度良く原子核質量値が求められている既知α娘核まで到達できる．そこから，各々のα壊変エネルギー(≒$Q_{lpha }$)を積み上げていくことによって，超アクチノイド元素の原子核質量を精度良く決定することができる．しかしながら，α壊変連鎖の途中に位置する中性子不足アクチノイド核種の分岐比の小さいα壊変特性のために，そのα壊変エネルギーの情報を得ることができず，超アクチノイド元素の原子核質量を正確に決定することができない．またさらに，中性子不足アクチノイド核種は，$Q_{athrm{EC}}$($> 3$ MeV)が大きく，娘核の核異性体の寿命が長いのが特徴で，特異的な核分裂過程である電子捕獲遅延核分裂(EC-delayed fission)を起す可能性が高い．この核分裂過程は，超新星爆発時の元素合成過程解明の鍵を握るβ壊変遅延核分裂と相補的な関係であるので，中性子不足アクチノイド領域核種の詳細な壊変特性データが得られるならば，今後の元素合成過程解明の基礎データとなる．)

(Summary) We have recently have developed an in-situ multiple-channel depth distribution spectrometer (DDS) that can easily acquire on-site measurements of the depth distribution of specific radioactivities of Cs-134 and Cs-137 underground. Despite considerable improvements in the hardware developed for this device, the quantitative method for determining of radioactivities with this DDS device cannot yet achieve satisfactory performance for practical use. For example, this method cannot discriminate each γ-ray spectra of Cs-134 and Cs-137 acquired by the 20 thallium-doped caesium iodine CsI(Tl) scintillation crystal detectors of the DDS device from corresponding depth levels of underground soil. Therefore, we have applied deep learning neural network (DLNN) as a novel radiation measurement technique to discriminate the spectra and to determine the specific radioactivities of Cs-134 and Cs-137. We have developed model soil layers on a virtual space in Monte-Carlo based PHITS simulations and transported γ-ray radiation generated from a particular single soil layer or multiple layers as radiation sources; next, we performed PHITS calculations of those specific radioactivity measurements for each soil layer using DDS device based on machine learning via the DLNN algorithm. In this study, we obtained informative results regarding the feasibility of the proposal innovative radiation measurement method for further practical use in on-site applications.

(Summary) We report the first ionization potentials (IP) of the heavy actinides, fermium (Fm, atomic number Z = 100), mendelevium (Md, Z = 101), nobelium (No, Z = 102), and lawrencium (Lr, Z = 103), determined using a method based on a surface ionization process coupled to an online mass separation technique in an atom-at-a-time regime. The measured IP values agree well with those predicted by state-of-the-art relativistic calculations performed alongside the present measurements. Similar to the well-established behavior for the lanthanides, the IP values of the heavy actinides up to No increase with filling up the 5f orbital, while that of Lr is the lowest among the actinides. These results clearly demonstrate that the 5f orbital is fully filled at No with the [Rn]5f7s configuration and that Lr has a weakly bound electron outside the No core. In analogy to the lanthanide series, the present results unequivocally verify that the actinide series ends with Lr.

(Summary) Following the Fukushima Nuclear Power Plant accident, the Japanese government created two supplemental texts about radiation reflecting the accident for elementary, middle school, and high school students. These texts were made to explain radiation and consequently to obtain public consent for the continuation of the nuclear program. The present study aimed to evaluate the appropriateness of the content of the texts and to collect the basic data on the level of understanding necessary to improve radiation education. Lectures on radiology including nuclear energy and the Fukushima accident were given to 44 fourth-year dental students in 2013. The questionnaire was administered in 2014 when these students were in their sixth-year. The survey was also administered to 40 first-year students and 41 fourth-year students who hadn't any radiology lectures. Students rated their level of understanding of 50 phrases used in the texts on a four-point scale (understanding = 3, a little knowledge = 2, having heard = 1, no knowledge = 0). Questions on taking an advanced physics course in high school and means of learning about radiation in daily life were also asked. The level of understanding of phrases in the supplemental text for middle and high school students was significantly higher among sixth-year students (mean = 1.43) than among first-year (mean = 1.12) or fourth-year (mean = 0.93) students (p < 0.05). Overall, the level of understanding was low, with scores indicating that most students knew only a little. First-year students learning about radiation from television but four-year and six-year students learning about radiation from newspaper scored significantly higher (p < 0.05). It was concluded that radiation education should be improved by using visual material and preparing educators to teach the material for improving the public's understanding of radiation use-especially nuclear power generation because the phrases used in the supplementary texts are very difficult for students to understand.

(Summary) Although the accumulation and distribution of metals from metallic orthodontic appliances in the oral mucosa have been studied extensively, they remain unclear because their concentration is quite low. In this study, metal specimens (Ni, Ni-Ti, and Co-Cr) were sutured in the unilateral oral mucosa of rats, and the distribution of the eluted elements in the mucosal tissue was estimated using inductively coupled plasma mass spectrometry (ICP-MS) and synchrotron radiation X-ray fluorescence analysis (SR-XRF). While the infiltrations of Ni, Co, and Cr into the oral mucosal connective tissue were observed with SR-XRF, significant increases were only found in Ni from the pure Ni group and Cr from the Co-Cr group. Furthermore, Ni and Co were estimated as hydrated ions while Cr was estimated in oxide form through X-ray absorption fine structure (XAFS) analysis.

(Summary) Although iron is an essential trace metal, its presence in excess causes oxidative stress in the human body. Recent studies have indicated that iron storage is a risk factor for type 2 diabetes mellitus. Dietary iron restriction or iron chelation ameliorates symptoms of type 2 diabetes in mouse models. However, whether iron content in the body changes with the development of diabetes is unknown. Here, we investigated the dynamics of iron accumulation and changes in iron absorption-related genes in mice that developed obesity and diabetes by consuming a high-fat diet (HFD-fed mice). HFD-fed mice (18-20 wk) were compared with control mice for hematologic features, serum ferritin levels, and iron contents in the gastrocnemius muscle, heart, epididymal fat, testis, liver, duodenum, and spleen. In addition, the spleen was examined histologically. Iron absorption-related gene expression in the liver and duodenum was also examined. Hemoglobin and serum ferritin levels were increased in HFD-fed mice. The HFD-fed mice showed iron accumulation in the spleen, but not in the heart or liver. Increased percentages of the splenic red pulp and macrophages were observed in HFD-fed mice and iron accumulation in the spleen was found mainly in the splenic red pulp. The HFD-fed mice also showed decreased iron content in the duodenum. The mRNA expression of divalent metal transporter-1 (DMT-1), an iron absorption-related gene, was elevated in the duodenum of HFD-fed mice. These results indicate that iron accumulation (specifically accumulation in the spleen) is enhanced by the development of type 2 diabetes induced by HFD.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society, Vol.2013 35th, 858-861, 2013. (Summary) We have developed bone cement introducing Strontium (Sr) to promote early bone regeneration. To prolong the release duration of Sr, we applied inorganic Sr filler for containing into the cement powder. The purpose of this study is to evaluate the mechanical properties, crystallinic properties, and ion release activities, especially Sr anion, of this cement. Alpha-TCP powder was mixed with Sr filler, with 0.1wt%, 0.5wt%, 1.0wt%, and 5.0wt%. These were mixed with mixing liquid and formed for each test. They were incubated and crystalized in 95% moisture for 1 week. The mechanical properties were studied by the compression, the diametral tensile strength and 4-point vending. Tested specimens were evaluated by X-ray diffraction(XRD) and scanning electron microscopic(SEM) imaging. The ion release behaviors were measured by inductively coupled plasma mass spectrometry(ICP-MS). The mechanical properties were increased in consistency of filler, but decreased in some samples because of declining the apatite matrix. And the Sr release showed interesting results as the sequential resource of Sr. By adjusting the mixing ratio or considering the application of these Sr releasable cements, this material would show good performance by its strength and longer Sr release for bone regeneration.

(Summary) Purpose: Our purposes were to establish suitable conditions for proton magnetic resonance spectroscopy (MRS) to measure dynamic changes in alcohol concentration in the human brain, to evaluate these changes, and to compare the findings with data from analysis of breath vapor and blood samples. Materials and Methods: We evaluated 4 healthy volunteers (mean age 26.5 years; 3 males, one female) with no neurological findings. All studies were performed with 3-tesla clinical equipment using an 8-channel head coil. We applied our modified single-voxel point-resolved spectroscopy (PRESS) sequence. Continuous measurements of MRS, breath vapor, and blood samples were conducted before and after the subjects drank alcohol with a light meal. The obtained spectra were quantified by LCModel Ver. 6.1, and the accuracy of the MRS measurements was estimated using the estimated standard deviation expressed in percentage (%SD) as a criterion. Results: Alcohol peaks after drinking were clearly detected at 1.2 ppm for all durations of measurement. Good correlations between breath vapor or blood sample and MRS were found by sub-minute MRS measurement.

Minoru Sakama, Yusuke Nagano, Takuya Saze, Shogo Higaki and Takashi Kitade : APPLICATION OF ICP-DRC-MS TO SCREENING TEST OF STRONTIUM AND PLUTONIUM IN ENVIRONMENTAL SAPMLES AT FUKUSHIMA, Applied Radiation and Isotopes, Vol.ARI, No.6184, S0969-8043(13)00146-2, 2013. (Summary) An application of sequential automated SPE separation equipment coupled to the quadrupole-based ICPMS instrumentation with a dynamic reaction cell such as a screening test system of (90)Sr and Pu isotopes in environmental samples was developed in this work. So far, during the course of a large number of reports as to various specific radioactivities in environmental samples surveyed at radioactive contaminated area around the Fukushima Daiichi Nuclear Power Plants (FDNPP), there is a much smaller number of reports on (90)Sr and Pu isotopes than that of (134)Cs and (137)Cs since the FDNPP accident, and then it would be expected to develop the simple analysis method of these isotopes instead of radiation measurements currently in use. In particular, a screening for (90)Sr in environmental samples has been accomplished using an isotopic ratio measurement mode in comparison with the characterization on the Solid Phase Elution (SPE) separation between strontium and zirconium isotopes around the mass-90 fraction. As a result, for a trial analysis of environmental samples of a muddy snow water and a soil which were collected at Fukushima, it was found that the present developed system makes it applicable for achieving up to the specific activity levels of several hundreds Bq/kg ((90)Sr) and about 1-2Bq/kg (Pu isotopes) as the screening test system.

(Summary) alpha-gamma and alpha-electron coincidence spectroscopy for a short-lived heavy actinide nucleus (257)No (T(1/2) = 24.5 s) has been performed using a gas-jet transport system and an on-line isotope separator. Spin-parities of excited states in (253)Fm fed by the alpha decay of (257)No have been identified on the basis of the measured internal conversion coefficients. The nu3/2(+)[622] configuration has been assigned to the ground state of (257)No as well as to the 124.1 keV level in (253)Fm. It was found that the ground-state configuration of (257)No is different from that of lighter N = 155 isotones.

(Summary) Fluoride complexation of element 104, rutherfordium (Rf), produced in the 248Cm(18O,5n)261Rf reaction has been studied by anion-exchange chromatography on an atom-at-a-time scale. The anion-exchange chromatographic behavior of Rf was investigated in 1.9-13.9 M hydrofluoric acid together with those of the group-4 elements Zr and Hf produced in the 18O-induced reactions on Ge and Gd targets, respectively. It was found that the adsorption behavior of Rf on anion-exchange resin is quite different from those of Zr and Hf, suggesting the influence of relativistic effects on the fluoride complexation of Rf.

(Summary) The purpose of this study was to evaluate the reproducibility of in vivo quantitative proton MR spectroscopy (MRS) by repeated-measure analysis of variance and intraclass correlation coefficient (ICC) including assessment of both inter- and intrasubject variation. The concentration of metabolites was quantified using long-TR and short-TE stimulated-echo acquisition mode sequences with a quadrature head coil. All preparation procedures for MRS measurement except volume of interest determination were done by an automatic preparation scanning system equivalent to a clinical setting. Analyses were conducted by an LCModel running based on our original basis set by two different reference methods. The ICC showed a good correlation (r = 0.61-0.99) in any metabolite and almost the same value between the two different reference methods, but the concentration of myoinositol had a large intersubject variation. Our results suggest that the reproducibility of quantified metabolite concentration is acceptable in the clinical setting regardless of the reference method, although quantified values may have different intersubject variations.

(Summary) The EC and α decays of neutron-deficient Am and Cm nuclei have been studied using a gas-jet coupled on-line isotope separator. Decay schemes of the EC decay of <SUP>235, 236</SUP>Am have been constructed, and weak α decays of <SUP>233, 235, 236</SUP>Am and <SUP>237, 238</SUP>Cm have been observed. The efficiency of the on-line mass separation of Bk nuclei was measured to be ∼1%. The Q<SUB>α</SUB> values, α-decay partial half-lives, and proton-neutron configurations are discussed.

(Summary) We investigated the environmental radiation in Shikoku area using a car-borne survey and obtained the change of dose rate by continuous survey. Dose rartes in Ozu city and its surrounding area, Ehime prefecture were the lowest in other areas of Shikoku. Dose rates obviously changed on the north side of it's low dose rates area but gradually changed on the south side. Dose rates in Ashizuri-misaki, Kochi prefecture were the highest in Shikoku and changed in accordance with the boundary of geological structure. Dose rate on the survey route, from Imabari city in Ehime prefecture to Shimanto city in Kochi prefecture, was the lowest at the surrounding area of the prefectural boundary. This lowest dose rate was considered to be caused by geological structure. The influence of altitued on dose rates was not observed in this survey route.The average dose rates of environmental radiation in Ehime prefecture and Kochi prefecture were almost the same and the lowest in Shikoku. Tokushima prefecture was the highest in the average dose rates of environmental radiation of other prefectures in Shikoku.

(Summary) After the accident of the Fukushima Daiichi nuclear power plant by the Great East Japan Earthquake on March 11, 2011, concern about radiation is increasing and monitoring of environmental radiation is performed even in Kagawa Prefecture. Then, we investigated for a short period of time for the purpose of creating the dose rate distribution map of Kagawa Prefecture while getting to know the dose rate of each municipality in Kagawa Prefecture in detail using a car-borne survey technique. As a result of measurement, the dose rates were low in the plain regions and those became high in the mountainous regions. Due to the average value of each municipality, the dose rates of municipalities in the southeastern prefecture, which contain Izumi Group and mountainous region affluent in granite, were high. The average dose rates of all municipalities in Kagawa Prefecture were obtained from this investigation, and the dose rate distribution map was created. From the tendency of the dose rate distribution in Kagawa, it has confirmed that a dose rate changed with geographical feature or geology.

(Summary) The end of the late19th century, nuclear and radiochemistry was firstly constructed by one of great chemists, Marie Curie. At that time, she had carried out the first discovery of two new elements, polonium and radium, using chemical decomposition and separation methods of the first exercise in radiochemistry of uranium ores. Currently, nuclear and radiochemistry plays an important role in various fundamental and applied research fields from physics, chemistry, and biology, toward the environment, energy, industrial materials, life science, medicine, agriculture, education, and so on. This review is focused mainly on the introduction of current nuclear and radiochemistry, in particular, from the nuclear sciences of transuranium nuclides including recent experimental works of superheavy element chemistry toward radioactivity in the environment, inorganic analytical chemistry and the application of scientific technology to development of medical device.

(Summary) Beginning in FY2009, funding for the equipment cost of ICP-MS analytical system was allowed to insert it in the budget of The University of Tokushima. % The aim of equipping this new system is to educate the undergraduate students in the Department of Radiologic Science to understand and train advanced elemental and isotopic analyses, which are also available for their graduation researches on radiologic sciences. % In addition, this system also will be effectively shared among biomedical researchers who are with faculties of medicine, dentistry, and pharmaceutical sciences at Kuramoto Campus in The University of Tokushima. % In particular, the present ICP-MS analysis will be expected to contribute to measure quantitatively trace and macro amounts of metal elements (metallomics) relative to environmental radioactivity, biology, medicine, and so on. % Through this construction, we have developed the integrated analysis system composed of decomposing various shaped samples (i.e. soil, alloyed metal, urine, tissues, and so on) by a microwave sample preparation, isolating target elements automatically by a SPE (Solid Phase Extraction) method, and measuring their signal intensities sensitively and effectively mass-separated using an unique ICP-DRC-MS (Dynamic Reaction Cell) type. % In this presentation, we have studied the experimental condition under this development.

Minoru Sakama, Takuya Saze, 北出崇 and 敷野修 : Development of elemental and isotopic analyses of uranium, thorium, and macro elements in the environment using an automatic SPE injection equipment coupled to ICP-DRC-MS, 第54回放射化学討論会, Sep. 2010. (Summary) Beginning in FY2009, funding for the equipment cost of ICP-MS analytical system was allowed to insert it in the budget of The University of Tokushima. The aim of equipping this new system is to educate the undergraduate students in the Department of Radiologic Science to understand and train advanced elemental and isotopic analyses, which are also available for their graduation researches on radiologic sciences. In addition, this system also will be effectively shared among biomedical researchers who are with faculties of medicine, dentistry, and pharmaceutical sciences at Kuramoto Campus in The University of Tokushima. In particular, the present ICP-MS analysis will be expected to contribute to measure quantitatively trace and macro amounts of metal elements (metallomics) relative to environmental radioactivity, biology, medicine, and so on. Until now, we have developed the integrated analysis system carried out from decomposing various samples, to isolate target elements automatically by a SPE (Solid Phase Extraction) method, and to measure their signal intensities quantitatively mass-separated using an unique ICP-DRC-MS (Dynamic Reaction Cell) type. In this presentation, we have reported the experimental condition under this development. (Keyword) radiochemistry / radiochemistry / uranium / 同位体比

(Summary) Recently, from a radiation safety management point of view, it has been discussed to construct guidelines on estimation of neutron fluxes produced via operating various medical small accelerators and to establish uniformly the clearance system related to having neutron activation effects into each accelerator facility. That is, it was the aim of this investigation to accumulate the data on estimation basis of neutron flux measurements at those medical small accelerators by an activation foil method and activation activities of materials in the accelerator facilities. In this work, the neutron fluxes at the 18 MV electron liniac apparatus of Hiroshima University Hospital have been measured by an activation Au foil method and activation activities of screws of wall sockets. For the activation activities of the screws of wall sockets, an 1115.55 keV gamma-ray peak of 65Zn produced via a 64Zn(n,γ)65Zn reaction was observed at each screw sample in the medical 18MV electron liniac room. The screw sample has contained about 35% zinc and 60% copper which were measured by an X-ray fluorescence analysis, and an isotope abundance of 64Zn is 48.6% in zinc isotopes. As a result of activation activities of 65Zn in the screws of wall sockets, it was also found that the thermal neutron fluxes would be distributed all around the electron liniac room and the measured values are over the range 3.3×104 to 9.9×104 cm-2 s-1.
