Yasaman Amiri; Behjat Ghasemi; Zahra Shahbazi-rad

Volume 3, Issue 2 , May 2022, Pages 1-6

  In this study , cold atmospheric pressure plasma jet used in treatment application was studied using COMSOL Multiphysics with the Finite Element Method . The device operates with argon gas at atmospheric pressure and by an alternating current power supply . Effective plasma parameters for treatment such ...  Read More

Synthesis of hydroxyapatite through solid-state reaction method and study of its thermoluminesence dosimetric properties against gamma rays

Parisa Taghipour; Farhad Zolfagharpour; Hamideh Daneshvar

Volume 3, Issue 2 , May 2022, Pages 7-10

  In this research work, powder hydroxyapatite samples were synthesized using a solid-state reaction method to investigate the annealing effect. The crystal structure was carried out by XRD system produced data, and the Rietveld method using MAUD software. The samples were irradiated in different radiation ...  Read More

Shahryar Malekie; Sedigheh Kashian; Seyed Musa Safdari; Morteza Akbari; Arjang Shahvar

Volume 3, Issue 2 , May 2022, Pages 11-15

  In this experimental work, Polycarbonate/Bismuth Oxide (PC-Bi2O3) nanocomposites were prepared in various concentrations of 0, 10, 30, and 50 wt% with thicknesses of 1 mm and irradiated by a pure beta-emitter source of Sr-90. To fabricate the electrodes, copper sheets with thickness of 100 µm were ...  Read More

Replacement of SF₆ with N₂/CO₂ in design of a parallel-fed voltage multiplier for electrostatic accelerator

Oveis Hasanpour; Fereydoun Abbasi Davani; Farshad Ghasemi; Mahdi Aghayan; Mohammad Nazari; Shahin Sanaye Hajari

Volume 3, Issue 2 , May 2022, Pages 17-25

  Two main insulating gases of SF₆ and N₂/CO₂ mixture are employed to increase voltage capability of electrostatic accelerators. SF₆ offers more insulating capability, but environmental and technical disadvantages of SF₆ makes usage of N₂/CO₂ mixture a desirable option. This paper aims to ...  Read More

Experimental study of the film badge as an alternative personal dosimeter for thermal neutrons

Amir Moslehi; Mohammad Hossein Choopan Dastjerdi

Volume 3, Issue 2 , May 2022, Pages 27-30

  In the present work performance of film badge as an alternative personal dosimeter for thermal neutrons is investigated. To do this, a cadmium-lead (Cd-Pb) filter with the same thickness as the tin-lead (Sn-Pb) filter is attached to the AERE/RPS badge. Since thermal neutrons are mixed with gamma rays, ...  Read More

Study on the production of Cr-coated Zr-1%Nb tubes as an ATF evolutionary cladding candidate

Hamed Khodadadi; Amir Zareidoost

Volume 3, Issue 2 , May 2022, Pages 31-36

  After some accidents like TMI and Fukushima Daiichi, the belief that nuclear fuels can safely and reliably be used up to 65 MW.d/kgU was revised. Different short to long term concepts started to be assessed more seriously. Among these concepts, Cr-coated Zr cladding tubes were taken into consideration ...  Read More
