I. Extension of Radiation Sterilization for Commercial Production
The most fruitful result of our project in this year is “ The Philippines started to supply Bio‐N biofertilizers made by irradiated carrier”.

Super Water Absorbent (SWA) for Soil Conditioner in Semiarid /Arid Region
Hydrogel SWA is effectively produced from natural polymers, such as cassava starch by radiation cross-linking or radiation grafting
1 gram of the SWA absorbs 400 – 500 gram of water
Soil mixed with small amount of SWA canretain longer the scarce rain or irrigated water
Field tests in Vietnam showed crop yield increase by10-30% by the use of SWA

Conclusion Radiation application in industry, agriculture and
environmental protection will further develop to contribute for sustainable development in both developing and developed countries
Radiation medicine effectively improve health care through nuclear medicine diagnosis and radiation treatment of cancer
IAEA plays important roles for supporting MSs to develop nuclear applications
FNCA is implementing 5 projects to develop nuclear applications in member countries
