• RADIATION PROCESSING APPLICATIONS FOR HEALTH
  AND THE ENVIRONMENT
• Lead Country PHILIPPINES
• Project Lead Country Coordinator L. V. Abad
• 31st NRM, Tokyo, Japan, 21 24 April 2009

2

• OBJECTIVES
• - to apply radiation processing to natural
  polymers for use in the health and the
  environment sectors
• - to establish the appropriate radiation
  processing technology for environmental
  remediation
• - to promote the utilization of the developed
  radiation processing technology to end-users

• ACCOMPLISHMENTS
• Regional activities
• - Mid-Term Review Meeting, Quezon City, the
  Philippines, 7-11 April 2008
• - Regional Executive Management Seminar for
  Policy Makers and Entrepreneurs, Takasaki,
  Japan, 8-12 December 2008

5

• ACCOMPLISHMENTS
• National programs (13/14 participating MSs)
• a) Health applications
• - Different natural polymers available in
  the region (agar, carageenan, chitosan,
  polylactic acid, polysaccharide derivatives,
  HA-chitosan) have been modified by radiation to
  synthesize new products (hydrogel wound
  dressing, materials for tissue engineering
  applications incl. bone substitute, hydrogel
  for pain relief, drug delivery system,
  nanoparticles,). These products are at
  different stages of development and technology
  transfer (R D, pre-clinical trials, clinical
  trials, pilot scale, transfer to industry)

6

• ACCOMPLISHMENTS
• National Programs
• a) Health applications
• - modification of synthetic polymers
  (polyurethane, PVA, etc.) for the synthesis
  of new products at different stages of
  development
• b) Environmental applications
• - radiation-modified polymers for metal
  adsorption, soil conditioning
• - radiation is effective in degrading
  organic pollutants ( POPs, 4-Cl-phenol)

7

• ACCOMPLISHMENTS
• 2. National Programs
• b) Environmental applications
• - integrated EB-ion exchange-biological
  treatment for recycling of industrial
  wastewater of the textile and food
  beverage industries with large reduction in
  COD and BOD values
• - development of copolymer/composites by
  radiation for waste water treatment/
  enhanced oil recovery
• - development of nanomaterials

8

• ACCOMPLISHMENTS
• 2. National programs
• c) Radiation facilities development/upgrading
• - construction of 350 kCi Co-60 irradiator
  in Bangladesh
• - establishment of a multipurpose
  irradiation facility in Sri Lanka
• - upgrading of multipurpose irradiation
  facility (semiautomated handling system
  and loading of 150 kCi Co-60) in the
  Philippines
