    Mathematical simulation of radiolysis process in water under the influence of low-energy electrons
    (Azerbaijan National Academy of Sciences Institute of Radiation Problems ve Turkish Atomic Energy Authority, 2006) Jafarov, Y. D.; Bölüm Yok
    The physical (10-16-10-15 sec.) and physicochemical (10-14-10-11 sec.) stage of radiolysis process in liquid water under the influence of low-energy electrons were mathematically simulated using Monte-Carlo and single collision methods. Radiation-chemical yields of the products, formed from their conversions in shortliving electron-excited state created by inelastic collision between electrons and water molecules in physical stage of the process, in direct single ionization of different molecular orbitals (H20+...e- ion pair) and later in physicochemical stage were calculated.

    Pollution of oil fields by norm and related doses
    (Azerbaijan National Academy of Sciences Institute of Radiation Problems ve Turkish Atomic Energy Authority, 2006) Huseynov, V. I.; Guliyev, R. I.; Guliyev, E. G.; Naghiyev, J. A.; Jafarov, Y. D.; Bölüm Yok
    Peculiarities of pollution of oil production fields by naturally occurring radionuclides were investigated. It is established, that produced water is a main source of this pollution. Gamma-radiation background survey showed that pollution mainly has localized character and radioactive spots have sizes from few centimeters up to several meters and are separated each from other by hundreds meters. Levels of soil pollution in such spots were determined using gamma spectrometry. Using these results, exposure, equivalent and effective dose rates and annual effective dose were modeled. It is established that only spots with maximal observed levels of pollution and mean diameters more than 40 m can cause annual effective doses inside the spot exceeding limits allowed in Radiation Safety Standards.
