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 ofAu,Ni,Ag,Cu,Co,Ir andPd, and a shell comprising SiOsurrounding 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.
