Scientists inject rhinos with radioactive material in attempt to curb poaching

Researchers in South Africa have conducted a study to combat rhino poaching. They injected radioactive material into the horns of 20 rhinos, aiming to use radiation detectors at national borders to detect the horns and apprehend poachers. The process involves tranquilizing the animal, drilling a hole in its horn, and inserting the nuclear material. The research hopes to replicate this method to protect other vulnerable species. The global rhino population has decreased significantly due to high demand for their horns on the black market. South Africa, with the largest population of rhinos, has seen an increase in poaching since the easing of COVID-19 restrictions. Though the method has faced ethical objections, the researchers emphasize the low radioactivity dosage used.
