Wits-led project begins putting radioactive pellets into rhino horns to deter poachers

The Rhisotope Project, led by Johannesburg's University of the Witwatersrand, has begun inserting radioactive pellets into rhino horns to deter poaching. This innovative method aims to protect South Africa's rhino population by making their horns less attractive to poachers. The pellets, detectable at borders and airports, pose no harm to the animals but could deter illicit trade. With over 10,000 rhinos poached since 2008, this project offers a promising solution..Sign up for your early morning brew of the BizNews Insider to keep you up to speed with the content that matters.

Photographer: Cebisile Mbonani/Bloomberg.The Rhisotope Project, which is being run by Johannesburg's University of the Witwatersrand, is just one of a number of ways ranging from staining horns with dye to cutting them off that conservationists in the country with the world's biggest rhino population are seeking to protect the animals. It has the added advantage in that horns implanted with the pellets could be detected as they pass through borders, airports and harbors..The aim of the project, which this week installed the pellets in the horns of a large group of rhinos for the first time at an orphanage for the animals a three-hour drive north east of Johannesburg, is to make them unattractive to poachers. Since 2008 more than 10,000 rhinos have been killed illegally in South Africa, their horns sawn off and sold illicitly in east Asia where they are displayed as a sign of wealth, given as gifts and are erroneously thought to cure cancer. .The installation of a radioactive pellet into the horn of a rhinoceros. Photographer: Cebisile Mbonani/Bloomberg.A rhino named Beckham with a radioactive pellet drilled into his horn.."If we can get to that position where we make the horn significantly less attractive, significantly less valuable, then hopefully these animals get to live and breed," said James Larkin, a professor at the University of Witswatersrand who founded the project, as he operated a drill with rhinos being sedated before having the radioisotopes inserted and then being brought back to consciousness. .Read more: 🔒 Life Healthcare pivots from hospital chain to diagnostics as admissions plateau.While projects such as Rhisotope aimed at protecting the animals have proliferated in recent years, the number of rhinos killed by poachers in South Africa rose to a four-year high of 499 last year. That's left about 22,500 rhinos, of the white and smaller black variety, across Africa, of which 79% live in South Africa, according to government statistics..The dose levels are only slightly higher than naturally occurring radiation and will not harm the animals, according to the project's website. Still, buyers could fall ill if they consume enough of the horns. .The fact that the horns can be picked up by the more than 11,000 radiation detection monitors that have been installed at ports of entry globally could aid an otherwise limited number of border officials trained to detect wildlife trafficking. .Members of the Rhisotope Project prepare to install a radioactive pellet at a rhino orphanage in Limpopo province. Photographer: Cebisile Mbonani/Bloomberg.The Rhisotope Project started up in 2021 when it injected harmless stable isotopes into the horns of two animals named Denver and Igor. At the time some of its support came from Russia's state-nuclear company Rosatom. The program took a decision to end its relationship with the company after the war in Ukraine broke out, said Jessica Babich, a conservationist involved in the program. .Read more: 🔒 FT: SA proposes a controversial medical tourism plan involving rhino horns.The program is now searching for more funding from investors and donors, and may sell shares in the project. .If the 20 rhinos injected with the radioisotopes this week are healthy in six months time the service may be rolled out commercially at a cost of 24,000 rand ($1,317) per animal or less if larger groups are treated, Babich said. The radioisotopes in the horn need to be "topped up" after five years because it will grow and the radioactive half-life of the material weakens..James Larkin, founder of the Rhisotope Project..And, Larkin said, it's preferable to cutting the horns off, an increasingly common way of combating poaching. ."Nature doesn't waste energy growing something on the head of an animal if it doesn't need it," said Larkin, who has served as chairperson of the International Atomic Energy Agency. .Read also:.Howard Buffett, Walton Family among billionaires backing unprecedented effort to save white rhinosWe need to have an honest debate about farming rhino to save them – Jonathan OppenheimerWe need to have an honest debate about farming rhino to save them – Jonathan Oppenheimer.© 2024 Bloomberg L.P.
