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.

Neutron transmission measurements of U233 and U235 have been obtained from 0.02 to 0.08 ev. The 2200 m/sec total neutron cross section values have been calculated from a linear least-squares fit to the data in this region and found to be 587 ± 6 and 690 ±10 barns, respectively. The data were taken with the Materials Testing Reactor (MTR) fast chopper with an instrument resolution of 2 µsec/m. Experimental techniques, involving the use of a 1024-channel time-of-flight analyzer for measuring total cross sections at low energies, are described.
