Nuclear science education in Taiwan, 1956–1992

The nuclear science education has been established in Taiwan at the College of Nuclear Science, National Tsing Hua University since 1956, the only one among 123 universities and colleges in Taiwan where nuclear-related education is offered. The Nuclear/Radiochemistry program, with nine faculty members, offers bachelor's, master's, and doctorate degrees in Nuclear Science. Lectures and lab classes of nuclear chemistry, radiochemistry, and allied branches in health physics, nuclear instruments, nuclear engineering, nuclear medicine, radiation biology, and environmental monitoring are given to the 17 undergraduate students and 33 postgraduate students currently registered. Support from the well-developed local nuclear power industry and government agencies is converged with rapid growth rate toward the Nuclear/Radiochemistry program; the 1992 annual research contracts for the program amounted over one million US dollars. Careerplacement program for graduates is developed to orientate them into the local nuclear power utilities as well as agricultural, medical, industrial, academic, and govemmental sects where nuclear chemists and radiochemists at all levels are desperately needed.     

Nuclear-physical methods in macro- and microanalytical investigations of contamination with radionuclides at Semipalatinsk Nuclear Test Site

Summary The paper presents a complex of nuclear-physical methods developed in the Institute of Nuclear Physics of Kazakhstan National Nuclear Center for the investigations of the rate, character and peculiarities of contamination with radionuclides of the Semipalatinsk Nuclear Test Site (SNTS). The developed method combines both macroinvestigations (radionuclide analysis, NAA, XRFA, ESR- and NGR-spectroscopy) and microinvestigations (MS, micro-PIXE, electron microscopy). The results of the investigations at the main SNTS test sites “Opytnoye pole' and “Degelen' are presented.

Anwendung der neutronenaktivierungsanalyse zur bestimmung von chemischen elementen in heilschlamm aus einem österreichischen moorbad

The content of various elements of mud from Neydharting Austria, that is used for Fango therapy, was determined by neutron-activation analysis. ASTRA-reactor of the Research Centre Seibersdorf and the reactor of the Institute of Nuclear Energy of the Bulgarian Academy of Sciences, Sofia, were used. The concentrations of Ca, Cr, Sc, Fe, Zn, Rb and Co found in our laboratory were in good agreement with the results reported by the Institute of Nuclear Research and Nuclear Energy of the Bulgarian Academy of Sciences, Sofia. All investigated elements in mud with exception of the relatively high uranium values are in good agreement with the values obtained for the distribution of elements in different culture soils.

Education in nuclear science at IPEN - CNEN,São Paulo,Brazil: Advanced School of Nuclear Energy—EAEN

EAEN (Advanced School of Nuclear Energy, 2010) is an annual school that consists of a week of activities in the area of Nuclear Physics, Radiochemistry and uses of Nuclear Energy for a public made of high school students. The EAEN project represents a pioneering program on science education and dissemination of knowledge, conducted by researchers and focused mainly on high school and scientific education for the population in general. The school’s priority is to explore the failures and the lack of education in the dissemination of nuclear energy for high school students as well as to attract prospective students with great potential for graduate courses of IPEN and other institutions in Sao Paulo and in Brazil.

Compton suppression instrumental neutron activation analysis performance in determining trace- and minor-element contents in foodstuff

In 2003–2004, several food items were purchased from large commercial outlets in Coimbra, Portugal. Such items included meats (chicken, pork, beef), eggs, rice, beans and vegetables (tomato, carrot, potato, cabbage, broccoli, lettuce). Elemental analysis was carried out through INAA at the Technological and Nuclear Institute (ITN, Portugal), the Nuclear Energy Centre for Agriculture (CENA, Brazil), and the Nuclear Engineering Teaching Lab of the University of Texas at Austin (NETL, USA). At the latter two, INAA was also associated to Compton suppression. It can be concluded that by applying Compton suppression (1) the detection limits for arsenic, copper and potassium improved; (2) the counting-statistics error for molybdenum diminished; and (3) the long-lived zinc had its 1115-keV photopeak better defined. In general, the improvement sought by introducing Compton suppression in foodstuff analysis was not significant. Lettuce, cabbage and chicken (liver, stomach, heart) are the richest diets in terms of human nutrients.
