  1. 356. Behavior of cadmium(II) in irradiated aqueous solutions

    Radiation Chemistry
    Poster
    The radiation removal of cadmium(II) from aqueous solutions in presence of different scavengers has been investigated. 100 mg/L of cadmium dissolved from Cd(NO3)2 requires dose of 15 kGy to be effectively removed from the system containing 1×10-2 mol/L of HCOOK as a scavenger of OH radicals. The positive effect of deaeration with N2O or N2 was...

    Poster
    In this work, is analyzed the interactions of the γ-radiation with two alkali halide single crystals: NaCl doped with Ca2+ (0.3 %) or Mn2+ (0.3 %), at two irradiation temperatures (298 K and 77 K), and different doses at a fix dose rate, for their possible use as dosimeters. The irradiated crystals were analyzed using their thermoluminescence properties. The...

    Radiation Chemistry
    Poster
    In order to isolate long-lived radionuclides from the environment it is necessary to immobilize them into highly stable forms (matrices). Crystalline materials of the mineral-like type are considered to be the most promising form of the matrix incorporating high-level waste (HLW). Alpha particles and heavy recoil nuclei lead to the damage of actinide-containing crystalline phase structures of...

  4. 357. Radiation chemistry approach to the study of sedimentary microenvironments as models for the protection of bio-organic molecules on the early Earth

    Radiation Chemistry
    Poster
    Studies in radiation chemistry can provide a deeper insight into the chemical process that may have importance for chemical evolution studies that led to the origin of life. Chemical evolution encompasses the physical and chemical aspects that try to explain the origin/permanence of bio-organic compounds prior the appearance of life. Our aim is to stress the relevance of ionizing radiation as...

  5. 120. Radiographic effects during self-irradiation of curium intermetallic compounds
    Prof. Viacheslav Radchenko (JSC "State Scientific Center - Research Institute of Atomic Reactors")

    Radiation Chemistry
    Poster
    Considered are changes in the elementary cell volumes versus time at room temperature and annealing behavior of some curium intermetallic compounds with platinum metals (Pt, Ir, Rh and Pd) etc. caused by internal irradiation by alpha-decay products of radioactive component [1,2,3]. The intermetallide x-rays show that with increasing irradiation dose a decrease in the diffraction reflection...
