In a groundbreaking conservation initiative, scientists at the University of the Witwatersrand have begun injecting rhinoceros horns with low-level radioactive isotopes, an innovative strategy under the “Rhisotope Project” designed to deter traffickers by making horns easily detectable by radiation scanners at airports, ports, and border crossings.

This novel use of nuclear technology aims to disrupt the illegal trade in rhino horn by leveraging existing global security infrastructure. 

Extensive safety trials, including the treatment of 20 rhinos in a pilot phase, confirmed that the isotopes pose no harm to the animals. These tests also demonstrated that even a single horn, regardless of its location in luggage or cargo, can trigger radiation detectors effectively.

The project, now entering broader operational stages with additional rhino treatments, represents a bold fusion of science and conservation to protect a species facing severe poaching threats.
