  1. Safe, Green & Clean International Developments in Radiation Processing Paul Wynne – Director & General Manager Paul Wynne – Director & General Manager

  2. Irradiation Technologies - Established • Gamma & Electron Beam – Complementary technologies • Gamma – Mainly contract irradiation facilities • Electron Beam – Mainly Inhouse manufacturing

  3. Irradiation Technologies - Developing • X-ray is becoming increasingly viable • X-ray targets convert electrons to photons • Photons – isotopic v directional • Dose rate and dose uniformity ratio (DUR) • Low energy uses & systems are also developing fast

  4. Industrial Developments in Radiation Processing Global terrorism; security concerns over use of radiological material Ignoranceof nuclear technologies; contribution to global health & wellbeing Alternativetechnology debate; - pressure to consider alternatives Cobalt supply considerations – operational & commercial concerns Technologicaldesign improvements; especially for electron beam New Applications; food safety & security, environmental & health

  5. Global Terrorism • Member States – Primary responsibility for security national governments. • IAEA role - developing & harmonizing policies, laws and regulations. • Users/Operators are responsible for the implementation of laws, regulations and best practice obligations.

  6. Global Terrorism • 10 CFR Part 37 implementation

  7. Global Terrorism

  8. Ignorance v knowledge

  9. Ignorance v knowledge 17

  10. Alternative Technologies

  11. Alternative Technologies • The flux of photons have similar properties • X-ray targets convert electrons to photons • Photons – isotopic v directional • Dose rate and dose uniformity ratio (DUR) • Incremental doses

  12. Alternative Technologies • Re-registration (for established products) – cost, time, changes in regulation • Material compatibility • Familiarity & risk aversion • Limited availability • First mover reluctance Conclusion: There are many reasons to conclude that change will happen slowly

  13. Cobalt Supply Considerations • Supply availability and cost • Transportation • Disposal

  14. Technological Development • Gamma • Control systems • Security • Eb & X-ray • High energy • Low energy • Control systems

  15. New Applications & New Challenges

  16. Summary and Conclusions • Radiation Processing • Be proud and tell our story • “Our Work Protects Your World”* • Collaboration is vital • Safe, Green and Growing • Steris
