  1. بسم الله الرحمن الرحيم Radioactive waste management Presented by:Hajo Idriss Researcher Sudan atomic energy commission RSI hjoidriss@gmail.com

  2. Radioactive waste Define as the type of waste consist of radionuclides exceed the level a adopted by IAEA

  3. Philosophy of radioactive waste management Protection of people and environment from the harmful effects of ionizing radiation

  4. Basic concept radiation protection • Time • Shielding • Distant

  5. Sources of radioactive waste • Oil drilling : NORM waste {238U ,226Rn 222Rn} • Mining : {238U ,226Rn 222Rn} • Medical : {60Co ,137Cs and 125,131I} • Industry : {90Sr ,192Ir and Am Be } • Reactor {Spent fuel and Fuel processing} • Military :depleted uranium

  6. Spent fuel NORM

  7. Military industry Medical

  8. Classification of radioactive waste Type of radiation physical Properties chemical Properties activity Half-life gamma Liquid high long Acidic neutron gas intermediate medium Alkaline alpha low beta short Solid

  9. Applicability • Planning assumptions • Concept of operations • Logistics • Plan maintenance

  10. Am-Be

  11. 192Ir

  12. 192Sr

  13. 60Co

  14. 99mTe

  15. Health risk of radioactive material • How does radioactive material case health effect ? • strip away electrons from atoms • break some chemical bonds

  16. What kinds of health effects does exposure to radiation cause? • stochastic • non-stochastic

  17. Is any amount of radiation safe? There is no firm basis for setting a "safe" level of exposure above background for stochastic effects.

  18. How do we know radiation causes cancer???????????????????? (depend on human immune system)

  19. Aren't children more sensitive to radiation than adults? • Yes, because • children are growing more rapidly • there are more cells dividing

  20. Type of radiation exposure Inhalation Ingestion

  21. Ingestion Internal External

  22. Health effect of radioactive material health effect of radiation DU 60Co

  23. Radiation detection instrument

  24. Contamination measurement

  25. Safety equipment

  26. Radiation accident

  27. Any question
