Production and Application of Radionuclides

Verbal

To perform chemical experiments of superheavy elements (SHEs) on a single-atom scale, it is important to investigate the optimal experimental conditions in advance using long-lived and carrier-free radiotracers of their homologue elements. The isotopes 95gNb (T1/2 = 34.991 d) and 179Ta (T1/2 = 1.82 y) are the useful radiotracers for the basic studies of element 105, Db [1,2]. In this work, we...

110. Production of 236gNp and 236Pu in proton induced nuclear reactions on natU

Production and Application of Radionuclides

Verbal

Radiochemical analysis of 237Np is important in a number of fields, such as nuclear forensics, environmental analysis and measurements throughout the nuclear fuel cycle. However analysis is complicated by the lack of a stable isotope of neptunium. Although various tracers have been used, including 235Np, 239Np and even 236Pu, none are entirely satisfactory. However, 236gNp would be a better...

35. Synthesis of the radioisotope Mn-56@SiO2, Sm-153@SiO2, and Dy-165@SiO2 hybrid nanoparticles for radiotracer

Production and Application of Radionuclides

Verbal

Radioisotope hybrid nanoparticles (NPs) such as Mn-56@SiO2, Sm-153@SiO2, and Dy-165@SiO2 were synthesized by neutron irradiation of the Mn-55@SiO2, Sm-150@SiO2, and Dy-163@SiO2 NPs using HANARO research reactor, respectively. The Mn-55@SiO2, Sm-150@SiO2, and Dy-163@SiO2 NPs were synthesized by calcinations of the hybrid NPs, which is prepared by sol-gel reaction of tetraethyl silicate in...

250. Preparation of Enriched Nickel- 63 for nuclear β-voltaic batteries

Production and Application of Radionuclides

Verbal

Modern technology in the field of microsystem technology allows producing subminiature and reliable devices for engineering and medicine. Energy for these devices should be also supplied from miniature and reliable power sources with a long service life. Atomic batteries (AB ) on the β-voltaic effect (the analog of the photovoltaic effect) most fully meet these requirements. Among possible β-...

22. Evaluating the Irradiation and Processing History of Potential Radiological Device Materials

Production and Application of Radionuclides

Verbal

Cobalt-60 and iridium-192 sources are both generated in nuclear reactors through the irradiation of stable target materials. However, variation in: neutron energy, flux and irradiation time; target material characteristics and purity; the activation cross sections of the desired reactions; decay and daughter progeny in-growth; and any post irradiation processing, can play a key part in...

70. Two-stage polonium evaporation from liquid lead-bismuth at low temperature

Mr Borja Gonzalez Prieto (SCK-CEN and KU Leuven)

Production and Application of Radionuclides

Verbal

Understanding polonium evaporation from liquid lead-bismuth eutectic (LBE) is crucial for the safe design of innovative spallation targets and accelerator driven systems in which LBE is used as target material and coolant. Po evaporation from LBE has been investigated by several research groups in the last decade [1-5]. However, these evaporation experiments were carried out at higher...

90. Ionchromatographic Isolation of n.c.a. Se-73,75 and New Cross Sections of its Impurity As-74 with 40 MeV Protons

Production and Application of Radionuclides

Verbal

Selenium-73 (half-life: 7.1 h; positron energy = 1.3 MeV) is a very promising radionuclide for application in positron-emission-tomography (PET). With its optimal radionuclidic properties it is the only suitable option for PET-tracer analogues of sulfur-compounds and for authentic labelling of organic selenium molecules [1]. It is preferably produced by the nuclear reaction As-75(p,3n)Se-73 in...
