In South Africa, radioactive material has been injected into the horns of rhinos to prevent poaching.
The researchers inserted the tiny radioactive chips into the animals as part of a research project. The goal is that with the help of radioactive material it would be easier to detect animal horns at border stations.
Radioactive material does not affect the animal’s health in small doses.
Most of the world’s rhinos live in South Africa.
