Overview

• Five wild rhinos in Mokopane were injected on July 31, marking the transition from pilot trials to operational rollout
• Low-dose isotopes have been shown to be harmless to rhinos while reliably triggering standard customs radiation scanners
• Tests confirmed that isotope-tagged horns can be detected even when concealed inside full 40-foot shipping containers
• The University of the Witwatersrand is urging private reserves and public custodians to enroll their rhinos for mass isotope tagging
• The project has secured support from the International Atomic Energy Agency to link tagged horns with global radiation-detection infrastructure
