IAEA program uses radioisotopes to protect rhinos
After two years of testing, the International Atomic Energy Agency and the University of the Witwatersrand in Johannesburg, South Africa, have begun officially implementing the Rhisotope Project, an innovative effort to combat rhino poaching and trafficking by leveraging nuclear technology.

The fission product spectra in discharged fuel from fast fission power reactors have been calculated over a wide range of operating conditions (reactor operating times from 10 to 10,000 days and cooling times from zero to infinity). These calculations are based on recent yield data for fission of uranium and plutonium. From these calculated data are presented derived data of total curies and energy dissipation rates as functions of operating time and cooling time.
