In a groundbreaking initiative unveiled by scientists from the University of the Witwatersrand, South Africa is taking a bold step to deter poachers by injecting rhino horns with a harmless radioactive material. Dubbed the Rhisotope Project, this effort is designed to enable customs officers to easily identify and intercept smuggled rhino horns as they are trafficked worldwide. Despite the ongoing crisis where hundreds of rhinos are killed annually, the project promises a proactive approach to conservation, building upon six years of rigorous research costing approximately £220,000 ($290,000).

Radioactive Rhino Horns: South Africa's Innovative Anti-Poaching Initiative
South African scientists aim to combat rhino poaching by injecting horns with a harmless radioactive substance.
Professor James Larkin, a key figure in the project, emphasized the urgency of the situation, noting that poaching continues at an alarming rate—at least one rhino falls victim each day. In a pioneering pilot study involving twenty rhinos, researchers confirmed that the radioactive material used was completely safe for the animals. Collaboration with the International Atomic Energy Agency further bolstered the project's credibility, showcasing its potential to detect horns within large shipping containers.
Renowned conservationist Jamie Joseph hailed the Rhisotope Project as an "innovative and much-needed" initiative that could help disrupt the illegal poaching networks, though she cautioned that more stringent legislation and political support are essential for a long-term solution. The annual poaching figures remain stark, with over 400 rhinos falling prey to illegal hunters in South Africa since 2021, according to the conservation charity Save the Rhino.
Jessica Babich, the head of the Rhisotope Project, reaffirmed their commitment to deploying this technology widely, aiming to protect African rhinos, both white and black, which are increasingly threatened by poachers driven by demand in Asian markets. The conservation community remains hopeful that this innovative approach might turn the tide in the ongoing battle against rhino poaching and safeguard a vital part of Africa's natural heritage.
