  1. TECHNOLOGICAL IRRADIATION ValentinMoise Head of IRASM Department IFIN-HH, Romania irasm@nipne.ro

  2. Industrial application of ionizing radiation: • Modification of properties of products/materials by irradiation • Sterilization • Crosslinking (polymerization, grafting, degradation, etc) Gamma (Cobalt-60, up to 12MCi) E-beam (<10MeV, up to 560kW) X-Ray (<7.5 MeV) - cold process - high penetration (gamma, X-ray) - high productivity (high dose rate - e-beam) 93rd Meeting in Bucharest-Magurele, October 12-13, 2018

  3. Crosslinking • Cables • Pipes • Heat-shrinkable • Wrap-foils • (automotive, aero-space) Radiation sterilization • Sterilization of single use medical devices, pharmaceutical packaging and active ingredients • Food irradiation • Cultural Heritage Preservation Degradation • PTFE recovery • Plant growth promoters (chitosan, carragenan) Gemstone irradiation 93rd Meeting in Bucharest-Magurele, October 12-13, 2018

  4. IRASM - MULTIPURPOSE IRRADIATION FACILITY • Department of IFIN-HH since 2000 (1993-1999: IAEA TC Project) Industrial Co-60 irradiator • Research Co-60 irradiator • Self shielded (max 14kCi) • 5dm3 irradiation cell Laboratories -tote box conveyor (10m3) -250-500kCi (max.2MCi) -wet source storage • High dose dosimetry • Microbiology • Physical&Chemical testing • ICP-MS • GC-MS • FT-IR/FT-Raman • EPR • Mechanical, Colour, etc 93rd Meeting in Bucharest-Magurele, October 12-13, 2018 4 IAEA Consultants Meeting on “Quality Management Practices on Radiation Facilities” 03-06 July 2018 IAEA Vienna

  5. IRASM - MULTIPURPOSE IRRADIATION FACILITY Main products: ISO certifications Laboratory plasticware ready to use culture media vials, dropers, sprays (Grece) wound dressings blood lines, dyalisers (Bulgaria) pharmaceutical ingredients 9001, 13485, 11137, 15378, 17025, GMP archives feed stock peat soil 93rd Meeting in Bucharest-Magurele, October 12-13, 2018

  6. R&D topics: • Cooperation with industry: developing new products/improving products by g irradiation (2016-2021: ~1.5 M€ - 88% EU cohesion funds) • Cultural heritage: - treatment/consolidation of degraded wood - molecular marking for works of art • Radiation resistance: “Photonics devices under extreme operating conditions”; “Physical and numerical experiments for studying the laser accelerated particles and their interaction with crystalline materials” • Radiation ageing • On-line measurements • (10Gy – 10MGy, 0.1-50kGy/h) • Biotechnologies: - use of g irradiation in biotechnological processes with applications in bioeconomics - synthesis of bioactive compounds in the mycelia of the phytoparasitefungi • Textiles&leather: developing advanced eco-nanotechnology solutions for multifunctional textiles and leather treatments 93rd Meeting in Bucharest-Magurele, October 12-13, 2018

  11. EfficacyEfficiency Gamma irradiation for cultural heritage preservation • High energy photons penetrates any material, at any depth, for any shape • Biocidal effect can be characterized by statistical means (lethal dose, D10) • Large quantities can be treated in short time, with low costs Modern wooden sculptures , “Braila” Museum, Romania Museum collection of BucharestNationalTeather International Conference on Applications of Radiation Science and Technology, 24 to 28 April 2017, Vienna, Austria
