A South African startup that’s promoting the use of implanted radioactive pellets to deter the poaching of endangered animals such as rhinos is seeking venture capital support to roll out the project commercially. The Rhisotope Project, which began in 2021, last month inserted the pellets into the horns of 20 rhinos as the final research stage before marketing the technology. Now, in order to roll out the program, it needs to raise close to $1-million.
