JOHANNESBURG - There seems to be no abating the scourge of rhino poaching in South Africa.
Almost 500 rhinos were poached last year, that's an increase of 51 from 2022.
Now, scientists are going nuclear to stop the scourge.
They're injecting radioactive material into live rhino horns to make them easier to detect.
It also makes the horns poisonous for human consumption but poses no risk to the animals.
To tell us more about this is James Larkin from Wits University's Radiation and Health Physics Unit.
