Riaan has a National Diploma and National Higher Diploma in Nuclear Technology from Pretoria Technikon (now Tshwane University of Technology), a Master Degree in Physics from the University of Witwatersrand and a PhD in Physics from University of Pretoria. He has also completed several short courses in ISO management systems, health and safety management, risk assessment and environmental (radiological) risk assessment.
