[ 1 ] - مطالعه مقایسهای دو ساختمان با زیر ساخت متفاوت از نظر نفوذپذیری در برابر گاز پرتوزای رادن
Radon concentration was measured in ground floor of two buildings with moisture controlled sub slab construction and slab on the ground. Results show that radon concentration in ground floor of the building with moisture controlled sub construction is more than 11 times smaller than that of the building with slab on the ground. Also indoor radon concentration in this building is about %41 highe...
[ 2 ] - بررسی مقایسهای پاسخدهی و رفتار دزسنجهای گرماتاب فردی نوترون-گاما در میدانهای 241Am-Be و 252Cf
Neutron individual dosimetry is challenging subject in dosimetry field. Thermoluminescent dosimeter (TLD) is one of the types of personal dosimeters that is extremely used to determine the doses of neutron sources. Typically, this type of dosimeter is used in different centers with a variety of applications after calibration with a standard neutron radiation sources. Usually, materials of TL cr...
[ 3 ] - Design and calibration of a passive detector for separating neutron, proton and alpha particles in mixed radiation fields
In this study, calibration process was carried out for deigned new CR-39 nuclear track detector for protons, neutrons and alpha particles separately under the same etching condition. In order to aim this purpose, americium-beryllium standard source (241Am-Be) and Plexiglas phantom for neutron irradiation, brass collimators and americium standard source (241Am) for alpha irradiation and the acce...
