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.

Data obtained from three systems are presented and discussed in reference to the problem of radioactive carry-over in boiling reactors. Measurements of droplet carry-over have been made on a small scale laboratory boiling test unit and on a 600-psia loop under high purity water conditions using Cs137 tracer. Measurements have also been made on the Borax-III boiling reactor under actual operating conditions. Activation products present in the steam and condensate served as an indication of the radioactive carry-over. Analysis of the decay curves of the samples provided a means of differentiating activities carried as droplets from volatile radioactive carry-over.
