    The activity of leaves and roots of Pistia stratiotes from the Seversky Donets river has been measured. The visible activity of ¹³¹I in roots of plant is found. The content estimate of ¹³¹I in water of Seversky Donets river ...
  • Reconstruction of energy dependence of the sensitivity of CdZnTe- and TlBr-detectors through the restricted data 
    Skrypnyk, A.I. (Вопросы атомной науки и техники, 2014)
    Monte-Carlo method is used for investigating the energy dependence of sensitivity of CdZnTe- and TlBr-detectors of gamma-radiation, which operate in the mode of pulse-amplitude analysis. We researched the approximate ...
  • Resonant RF electromagnetic field input in the helicon plasma ion source 
    Alexenko, O.V.; Miroshnichenko, V.I.; Mordik, S.N. (Вопросы атомной науки и техники, 2014)
    Spatial distribution of RF electromagnetic field absorption by a plasma electron subsystem of ion source is studied. An ion source operates in a helicon mode (wci < w < wce < wpe). A simplified model of plasma RF source ...
  • Searches for SUSY at the LHC 
    Obikhod, T.V. (Вопросы атомной науки и техники, 2014)
