Researchers in South Africa have begun a unique project to protect rhinos from poaching by injecting their horns with radioactive material. The aim is to make it easier to detect the horns as they cross borders, using existing radiation detectors designed to prevent nuclear threats.
The project, led by Professor James Larkin at the University of the Witwatersrand's Radiation and Health Physics Unit, involved tranquilizing 20 rhinos and inserting isotopes into their horns. This process, which involves veterinarians and nuclear experts, is intended to deter poachers and aid authorities in intercepting trafficked horns.
The team hopes this method can be expanded to safeguard other vulnerable wildlife, such as elephants and pangolins, from illegal hunting and trafficking.
"We are leveraging global radiation monitoring networks to enhance border security and combat wildlife crime," explained Professor Larkin, highlighting the project's innovative approach to conservation.
