About Rhisotope Project:
- It was started in 2021 in South Africa.
- It aims to make the rhinoceros horns easier to detect at border posts and render them useless for human consumption.
- The project involves inserting two tiny radioactive chips into the horns of 20 rhinos.
- The low-dose radioactive material is designed to be detectable by radiation sensors at international borders without harming the animals or the environment.
- The radioactive material is expected to last five years on the horn, making it a more cost-effective solution than dehorning every 18 months. Additionally, the team sprayed 11,000 microdots on each treated horn for further identification.
- The team of scientists will take follow-up blood samples to ensure the rhinoceroses are effectively protected.
- South Africa, home to the majority of the world’s rhinos, has been battling a poaching crisis driven by demand from Asia, where rhino horns are used in traditional medicine.
Q1: What is Radioactivity?
Radioactivity is the physical phenomenon of certain elements – such as uranium – of emitting energy in the form of radiation. This energy comes from the decay of an unstable nucleus.
