Abstract
Heteronuclear radioisotope nanoparticle of core-shell structure and a preparation method thereof are provided. The Heteronuclear radioisotope nanoparticle of core-shell structure comprising core of two different radioisotopes selected from a group consisting of 198Au, 63Ni, 110mAg, 64Cu, 60Co, 192Ir and 103Pd, and a shell comprising SiO2 surrounding the core.The Heteronuclear radioisotope nanoparticle of core-shell can be used as a tracer for the purpose of detecting variation of volume ratio or for the evaluation of the behavior characteristic of a water resource, based on information about phase ratio in the flow of multiphase fluid existing in a process which is operated under extreme condition such as high temperature and/or high pressure conditions.
