Nuclear tests to curb rhino poaching

Researchers in South Africa have injected radioactive material into the horns of 20 rhinos to combat poaching, leveraging global radiation detection systems at border crossings to intercept traffickers. This initiative, led by the University of the Witwatersrand, involves tranquilizing the animals and inserting isotopes into their horns. It's a novel approach to combat the drastic decline in rhino populations, which have plummeted due to poaching for horns sold on the black market. Critics question its effectiveness, noting poachers may bypass traditional border crossings.

• Radiation detectors at borders can now identify these treated horns, aiding authorities in arresting poachers.

• The process involves tranquilizing rhinos, drilling holes in their horns, and inserting nuclear material.

• The project is led by Professor James Larkin, leveraging global radiation monitors to combat poaching.

• Rhino populations have dropped from 500,000 two decades ago to 27,000 due to poaching, necessitating innovative solutions.

• Critics argue that poachers may bypass traditional border crossings, reducing the method's effectiveness.
