In South Africa, researchers have developed a new approach to deter poaching and protect rhinos from harm. Unlike previous methods that involved capturing and de-horning rhinos, this innovative technique uses radioactive isotopes to identify poachers.
Twenty live rhinos at a nursery in Limpopo province have had radioactive isotopes embedded into their horns. The idea behind this method is that the radiation emitted by these isotopes will be detected at any border crossing, identifying anyone who has handled a rhino horn. This makes it much more difficult for poachers to evade detection and sell their illicit horns.
Nuclear researchers at the University of the Witwatersrand’s Radiation and Health Physics Unit injected the isotopes into the rhinos as part of the project. Professor James Larkin, who led the project, explains that this new method leverages a global network of radiation monitors designed to prevent nuclear terrorism.
While poaching elephants for ivory is often driven by a desire for unique material, rhino horn poaching is motivated by illegal trafficking to criminal groups in Asia who falsely believe it has therapeutic properties. This innovative anti-poaching measure aims to protect these majestic animals from harm and preserve their populations for future generations.
Professor Nithaya Chetty, dean of the science faculty at Witwatersrand, reassures that the dosage of radiation used in this project was very low and extensively tested for any potential negative impacts on the animals. While existing methods have limitations, South Africa still loses numerous rhinos each year due to poaching. Innovation in poaching prevention is crucial in protecting these vulnerable creatures.
Overall, this new approach to discouraging poaching provides hope for Rhinos in South Africa and beyond by providing an effective way to identify those involved in illegal trafficking while minimizing harm to the animals themselves.
