[ 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 ] - اندازه‌گیری دز گامای ایجاد شده توسط نوترون‌های حرارتی در دزسنجTLD-700
Neutron response Induced in Thermoluminescence Dosimeter TLD-700 chips due to reactions of thermal neutrons with slab phantom and Badge Dosimeter TLD-600,700 materials in a neutron-gamma mixed field was measured. Using the linear relationship between thermal neutron fluence and the thermal neutrons induced TL response with slab phantom, Badge-TLD Materials, an empirical relationship was introdu...
[ 3 ] - 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...
[ 4 ] - بررسی جذب هسته پرتوزای Ra226موجود در آب به‌وسیلۀ جلبک سبز منطقه‌ای رامسر
In this research work, the biological effect of local green algae on adsorption of 226Ra concentration in 5 samples of hot spring̕ s water of Ramsar city has been investigated. To increase the cellular adsorption capacity of green algae it was first treated by one molar solution of NaCl for omission of obtrusive ions. The radioactivity of 226Ra in the samples was measured using HPGe spectrometr...
[ 5 ] - 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 ...
