South Africa has launched an innovative anti- poaching campaign, injecting rhino horns with radioactive isotopes to deter illegal trafficking.

Conservation scientists in South Africa are injecting rhino horns with radioactive isotopes. The doses are too weak to harm the animals, but strong enough to set off nuclear security system alarms at international border crossings.

In Mokopane, South Africa, researchers at the University of Witwatersrand, Johannesburg have launched the Rhisotope Project, an initiative that aims to disrupt the illegal rhino horn trade by making rhino horns radioactive. Don’t worry — this comes at no harm to the animals.
