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.

Measurements have been made of the anisotropy of neutron slowing down in Al-H2O plate lattices. The moments of the slowing down distribution from fission to 1.46 eV were determined in the two characteristic directions at two volume ratios using the point-source, point-detector method. For the 1:1 case, with an Al plate thickness of 0.25 in., the ages parallel and perpendicular to the plates were 65.4 ± 0.8 and 60.8 ± 0.8 cm2, respectively, giving an anisotropy of 1.076 ± 0.02. In the 2:1 (A1:H2O) case, with an Al thickness of 0.50 in., the corresponding values are 100.3 ± 1.5 and 92.5 ± 1.3 cm2, giving an anisotropy of 1.085 ± 0.02. The higher moments were characterized by higher anisotropics.
