Description

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 the presence of the complex precursors, in air flow at 500 ℃ for 8 h. Mn-55, Sm-150, and Dy-163 for radiotracers were selected because these elements can be easily gamma-activated from neutrons (activation limits: 1 picogram (Dy), 1-10 picogram (Mn), 10-100 picogram (Sm)). The successful synthesis of the radioisotope hybrid NPs were confirmed via Transmission Electron Microscopy (TEM), Energy Dispersive X-ray Spectrometer (EDS), Scanning Electron Microscopy (SEM), and Gamma spectroscopy analysis, respectively. The synthesized the radioisotope hybrid NPs could be used as radiotracers in science, environmental, engineering, and industrial fields.
