[ 1 ] - شبیه سازی آهنگ دز جذب شده سیب درختی در سامانه گاما سل 220 با استفاده از کد MCNPX
In this study, the dose rates in a gamma cell 220 device for apple were calculated by using MCNPX code in two states. In first state, apple uniformly fills the whole space of gamma cell. In second state, it was supposed that apples are spherical form that the empty space between them is filled by air. Generally, the results show that in both states the distributed dose rates are non-uniform. In...
[ 2 ] - اندازهگیری ضریب نفوذپذیری حرارتی محلول نانوذرات طلا با استفاده از پرتودهی گاما
Thermal diffusivity of Au nanofluid was measured by using a dual beam mode-mismatched thermal lens method. The samples were prepared in various sizes by utilizing the gamma radiation method. In the dual beam mode-mismatched thermal lens, a diode laser (532 nm) was used as an excitation beam and a He-Ne laser with the beam output at 632.8 nm was used as a probe beam. Thermal diffusivity of gold...
[ 3 ] - مطالعه دینامیک آبشاری اتم کائونیک نیتروژن به روش مونت کارلو
Cascade dynamics of kaonic nitrogen atom (K-N) in a gaseous target was simulated using a simple model. In this model the radiative transitions, internal Auger, K-electron refilling, nuclear absorption, and kaon decay processes were included. The effect of the K-electron refilling process on some of quantities of cascade dynamics such as X-ray yields, the averaged K-electron shell number, fract...
