-  Study on application on the purpose of environmental remediation and protection.

With those high practically applicable research orientations in the period of 2011-2015, R&D department had implemented 17 scientific researches in which 2 research contracts with International Atomic Energy Agency (IAEA), 3 ministerial projects, 1 pilot production project and 11 primary projects. The findings of the research have been meet requirement for radiation sterilization of medical items and food pasteurization as well as to expand the scope of radiation technology applications. In addition, many products have been commercialized at the center such as silver nanoparticles applied as an antibacterial, oligochitosan applied as resistance in agriculture and aquaculture, gold nanoparticles applied in cosmetics, supper water absorption (Gamsorb) and foliar fertilizer nanopolidone applied in agriculture and antibacterial cloth, plastic, water purification candle applied in medical and household. These products are the results obtained from the scientific research works.
