Synthesis and Characterization of LiAlO<sub>2</sub>for Passive Dosimetry

引用

World Journal of Nuclear Science and Technology 2022年第1期12卷 21-27页

作者： nguyen thi thu ha Trinh Van Giap Bui Duc Ky Institute for Nuclear Science and Technology Vietnam Atomic Energy Institute Hanoi Vietnam

Lithium aluminate (LiAlO2) powder was synthesized by sol-gel with EDTA method. The resultant powders were characterized by X-Ray Diffraction (XRD) and Scanning Electronic Microscopy (SEM) techniques. In addition, several thermoluminescence properties of synthesized LiAlO2 powder were reported. The results from X-ray diffraction (XRD), the powder prepared by sol-gel with EDTA method showed pure γ-phase when it was calcined at >900°C. Scanning electron microscopy (SEM) results show that the size of the lithium aluminate particles depended strongly on calcination temperature. The linearity is observed of synthesized LiAlO2 powder by sol-gel with EDTA with regression coefficient (R2) is 0.9971.

Thoron （Rn-220） is an invisible, odorless radioactive gas and nine times heavier than air. Purpose of project is to set up procedure to determine Rn-220 concentration which has been carried out in laboratory using Solid State Nuclear Track Detector （SSNTD） based passive detector technique. In this study, technical procedure has been applied in Karlsruhe diffusion chamber and LR-115, Type II strippable （Kodak Pathe, France） detector. The results have investigated how LR-115 work for Rn-220 by using Monazite ore to simultaneously measure Rn-222 and Rn-220. To carry out experiment, Karlsruhe diffusion chamber is used to with and without Poly-Ethylene （PE） membrane. Karlsruhe diffusion chamber with PE membrane only detect Rn-222, without PE membrane detect total Rn-222 and Rn-220. Precision evaluation by duplicate measure at 8 cm detector-source distance with relative standard deviation is less than 2.54%. Testing technical procedure, detectors have been sent to National Institute of Radiological Science （NIRS） for Rn-220 calibration exposure. After detectors have been calibration exposure at NIRS, it carried out all the following steps of procedure which set up at laboratory in 1NST, Vietnam. Finally, calibration factor calculated is 0.21 （tracks-cm2/Bq·m3·h） and constructed curve between integrated Tn-220 concentration and tracks density with factor R2 = 0.975.

上世纪九十年代起,随着经济效益的进一步提升,企业社会责任开始在世界范围内得到重视。与此同时,越南也紧跟世界经济潮流,开始愈加关注企业社会责任。越南通过不同手段促进企业履行社会责任,但碍于各种因素均未取得显著成效。台湾味丹公司驻越南分公司违规排放污水污染河流,Pouyuen公司为了满足生产经营需要无视防疫要求等案例,均体现出目前越南企业在履行社会责任方面的欠缺。在越南各类企业中,中小企业的重要性开始逐渐凸显,对于社会经济发展作用也愈发突出。本文以胡志明市中小企业为主要研究目标,对于其履行社会责任问题展开研究,分析胡志明市履行社会责任现状,并结合其驱动因素展开模型分析,并根据分析结果提出相应的措施加以改善。本文基于现有研究梳理胡志明市中小企业社会责任以及驱动因素主要内容,并结合假设的提出与模型的建立,通过问卷方式对于假设变量进行统计分析,结合分析结果发现:胡志明市中小企业企业履行社会责任存在不足,主要表现为企业承担不足、维护职工权益不到位等。引起上述问题的原因在于地方政府对于企业监管力度不足,企业并未建立相应理念以及员工缺乏维权意识等,并据此提出建议:胡志明市中小企业履行社会责任不仅需要发挥政府的监督与约束作用,同时还需提升社会组织监督作用,进而提高当地中小企业的履责积极性。本文立足于当前胡志明市中小企业对于社会责任的履行状况,对于其存在的问题加以改善,能够提供给更多的越南中小企业借鉴与参考,帮助其更好的履行社会责任。

Assessment of Radiation Dose Caused by Radioactive Gaseous Effluent Released from Nuclear Power Plant Ninh thuan 1 under Scenario of Normal Working Conditions

World Journal of Nuclear Science and Technology 2015年第3期5卷 183-191页

作者： nguyen Tuan Khai Do Xuan Anh Le Dinh Cuong Duong Duc Thang Vuong thu Bac nguyen thi thu ha nguyen Quang Long Trinh Van Giap nguyen hao Quang Institute for Nuclear Science and Technology (INST) Hanoi Vietnam Vietnam Atomic Energy Institute (VINATOM) Hanoi Vietnam

Based on guides RG 1.109, RG 1.111 published by United States Nuclear Regulatory Commission (USNRC), our research concentrates in assessing radiation doses caused by radioactive substances released from the nuclear power plant (NPP) Ninh thuan 1 under the scenario of normal operation using software package NRCDose72 provided by the USNRC. The database including the released radioactive nuclides, meteorology, terrain, population and agricultural production activities have been collected and processed to build the input data for the model calculation. The wind rose distribution obtained from the meteorological data in a five-year period from 2009-2013 showed that the radioactive nuclides released to environment spread in two main wind directions which are North East and South West. The X/Q (s/m3) and D/Q (s/m2) qualities which are, respectively, the ratio of activity concentration to release rate and that of deposition density of radioactive nuclides to release rate were calculated within an area of 80 km radius from the NPP site using XOQDOQ. Population doses were calculated using GASPAR. The XOQDOQ and GASPAR are two specific softwares in NRCDose72 package.

越南是东盟重要的成员国之一,从1986年进行“革新开放”的经济改革,越南经、政治社会体制也发生了重大的变化,劳动关系作为一个支撑经济改变稳定顺利进行的重要子系统。2007年1月越南正式加入WTO,越南丰富的劳动力资源为外资企业进入越南市场提供了良好的前景。这几年来,为提高越南劳工标准,越南的政府不断的修改劳工政策及法律法规,提升人工满意度。在此背景下在越的外资企业不但面临着市场竞争力,而且严格实行劳工标准使得企业成本增加,企业需要降低劳工的薪酬,导致劳资矛盾和冲突多发。因此,了解集体行动倾向和薪酬满意度的影响因素是一项重要而有意义的研究课题,希望此为企业管理者解决劳资关系冲突问题提供有益借鉴和思考。本研究从劳动关系视角出发,简单介绍越南企业劳动关系现状,基于社会认知理论和理性行动理论,分析劳动者的法律认知、薪酬满意度和集体行动倾向之间的关系,然后分析薪酬满意度在法律认知和集体行动倾向关系的中介作用,最后分析工会职能发挥感知对薪酬满意度和集体行动倾向的调节作用。从此提供庆和省如何解决劳动关系冲突管理的策略。本研究通过问卷调查了292员工样本,运用SPSS 21.0和AMOS 21.0数据分析软件进行数据分析以检验研究假设结构方程模型。研究结果显示:第一,法律认知对集体行动倾向具有显著负相关关系;第二,法律认知对薪酬满意度具有显著正相关关系;第三,薪酬满意度对集体行动倾向显著负相关关系;第四,薪酬满意度对法律认知和集体行动倾向具有显著中介作用;第五,工会职能发挥感知对薪酬满意度和集体行动倾向具有显著调节作用。基于上述结论,本文研究员工的法律认知、薪酬满意度、工会职能发挥感知和集体行动倾向之间关系,对政府、企业、工会以及员工提出了和谐越南劳动关系的建议。因此本研究在一定的程度上,丰富了劳资关系的理论模型,且具有实践的意义。

越南作为社会主义制度的发展中国家,自1989年经济革新以来,经济体制由计划经济向市场经济转变,由此带来了劳动关系规制的变化,而加入TPP则是越南劳动关系新的转折点。本文分析了越南劳动关系规制在加入TPP前后的转型过程和特征,发现其治理模式正由政府主导向劳资自治的模式转型,即政府将转变其角色,在市场失灵后调解劳资冲突,但与此同时有可能带来越南企业和劳工之间的冲突增多。本文最后建议中资企业在"一带一路"建设中实施在越投资战略时,需要考虑劳资冲突风险,并制订好相应的应对预案。
