[ 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 ] - ارزیابی پرتوگیری مردم از پرتوهای طبیعی زمینه گاما و رادن در شهر کاشان
In this research work public dose of Kashan inhabitants has been evaluated. Average annual effective dose due to inhalation of radon gas as well as external exposure to gamma rays have been evaluated to be 2.77±0.22 mSv and 0.97±0.05 mSv respectively. This leads to average annual public dose of 3.74 ± 0.22 mSv. Passive methods such as TLD pellets of LiF:Mg,Cu,P and polycarb...
[ 3 ] - اندازه‌گیری غلظت رادن در برخی ساختمان‌های مسکونی شهر کاشان
Radon concentration was measured in some dwellings in Kashan city. List of buildings was chosen randomly including old buildings made up of mud brick & clay and new buildings constructed with bricks and cement. Population weighted Radon concentration survey was followed and measurements were carried out using polycarbonate (lexan) track detector at the levels of basement to second floor of the ...
[ 4 ] - Evaluation of public exposure in high background natural radiation areas (HBNRAs) of Ramsar
Some areas in Ramsar, a northern city of IRAN, have the most natural radiation level in the world which is due to high concentration of 226Ra and its daughter products specially 222Rn and therefore these regions have been interested for radiation related investigations. The aim of this study also has been to evaluate public exposure in such areas in Ramsar, in order to obtain up to date informa...
[ 5 ] - 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...
[ 6 ] - Measurement of Contemporary and Retrospective Radon Concentration in Ramsar Dwellings Using Polycarbonate Detector
The origins of radon gas are the amount of uranium decay in the soil that is released into space and through the interior gaps of buildings. Radon can enter the respiratory system and cause radiation hazards. Recently research has identified Radon as the second leading cause of lung cancer after cigarette smoking. The indoor concentration of Radon progeny is mentioned as an important issue reg...
