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 cross section of 235U has been measured with a nominal resolution of 1 nsec/m from 20 eV to 100 keV. Structure is seen over the entire range with fluctuations as great as 40% in the range 10 to 100 keV. These measurements have an average absolute accuracy of 8% and are based upon the 6Li(n, α) cross section. Some questions are raised concerning existing cross sections that assume smooth energy variation in the region of 10 to 50 keV.
