Researchers in South Africa injected radioactive material into the horns of 20 rhinos to reduce poaching. The idea is for radiation detectors already installed at national borders to detect these horns and help authorities arrest poachers and traffickers. The research, involving veterinarians and nuclear experts, starts by calming the animal before carefully drilling a hole in the horn to insert the nuclear material. The researchers from the Health Physics and Radiation Research Unit at the University of Witwatersrand in South Africa injected these isotopes into 20 live rhinos. They hope the process can be replicated to save other vulnerable wildlife … Continue reading Can Radioactive Rhino Horns Prevent Poaching? South Africa Injects 20 Rhinos in Pioneering Study
