Rhinos go radioactive in the fight against poaching – Prof James Larkin

Every 20 hours, a rhino is poached in South Africa for its horn, with 35 rhinos lost in the Kruger National Park since the beginning of the year. The fight to protect these majestic animals is increasingly difficult, as rhino horn commands prices higher than gold, platinum, diamonds, and cocaine, according to Professor James Larkin from the University of the Witwatersrand.
In a groundbreaking effort, Professor Larkin and his team are combating rhino poaching by implanting harmless radioactive isotopes in rhino horns. This innovative approach leverages humanity's aversion to radioactive materials, effectively "piggybacking" on existing detection systems at international borders. The technology rollout is set to begin in July, with inquiries already coming in from Botswana. While Professor Larkin is cautious about calling it a "silver bullet," he sees it as a powerful new tool for anti-poaching rangers.
