[ 1 ] - بهینه سازی طیف نوترونی در بیم تیوب شمال غربی راکتور تحقیقاتی تهران جهت استفاده در روش درمانی نوترون تراپی با بور، توسط کد محاسباتی مونت کارلو
In order to gain the neutron spectrum with proper components specification for BNCT, it is necessary to design a Beam Shape Assembling (BSA), including moderator, collimator, reflector, gamma filter and thermal neutrons filter, in front of the initial radiation beam from the source. According to the result of MCNP4Csimulation, the Northwest beam tube has the most optimized neutron flux between ...
[ 2 ] - ارزیابی پرتوهای فرابنفش لامپ‌های کم‌مصرف از نوع فلورسنت فشرده
Iranians are replacing traditional incandescent lamps with Compact Fluorescent Lamps (CFLs), because they use about a quarter of the power of incandescent lamps and their lifecycle is up to ten times longer. Government encourages public to use CFLs too, for saving energy and reducing carbon dioxide emissions. Small amounts of mercury are used in CFLs, released to the environment if they are bro...
[ 3 ] - محاسبه طیف و شار نوترونی در سه بیم‌تیوب شمالی راکتور تحقیقاتی تهران برای استفاده در نوترون‌تراپی با بور با کد محاسباتی مونت کارلو
In order to investigate the possibility of using the T.R.R beam tubes in BNCT, it is necessary to select the best one from three north beam tubes. This beam tube should have more flux and better spectrum compared to others. So, after simulation of the last configuration of reactor’s core (NO.55) by MCNP4C code, the neutron flux and spectrum were calculated at the start, middle, and end of each ...
[ 4 ] - مقایسه آماری میزان نشتی امواج مایکروویو در اطراف فرهای مایکروویو خانگی وارداتی به ایران بین سال‌های 1384 الی1388
According to radiation protection regulations, microwave radiation intensity should not exceed general public exposure limit defined in "Iranian Standard-Non ionizing radiation-exposure limits". Based on this standard, exposure limit for microwave ovens, which work at 2450 MHz, is 1mW/cm2. By implementing such standard, about 575 imported ovens, including different models and brands w...
[ 5 ] - ارزیابی خطرات پرتوهای نوری در کاربردهای عمومی آن از دیدگاه حفاظت در برابر اشعه
Use of consumer products applying optical radiation (ultraviolet, visible and infrared radiation) sources is growing, in the society which also simplifies everyday ordinary jobs as well as raising the accuracy. There is some phobia in general public on such instruments that have not been approved scientifically. On the other hand optical radiation can cause health hazards especially for eyes an...
[ 6 ] - ارزیابی پرتوگیری مردم از آنتن‌های ایستگاه‌های تلفن همراه در کشور
Fast growth of the number of mobile phone subscribers in Iran, over the last few years, is the reason for construction of more and more base stations (BTS) especially in residential areas. As the BTS antennas emit radiofrequency (RF) electromagnetic energy, so it is the main concern of general public about their health and safety. The aim of this research work is to assess public exposure...
