Scientists test injecting radioactivity into rhino horns to deter poachers

Scientists are testing a novel technique to deter poachers targeting endangered rhinoceroses for their prized horns. As part of a pilot study in South Africa, researchers have injected small, radioactive pellets into the horns of live rhinos. The goal is to make the horns radioactive so there is less demand for them on the black market. Marize de Klerk reports from the UNESCO Waterberg Biosphere Reserve.
