zno and zno: mn nanocrystals synthesized via reverse micelle method. the structural properties nanocrystals were investigated by xrd and transmission electron microscopy (tem). the xrd results indicate that the synthesized nanocrystals had a pure wurtzite (hexagonal phase) structure. the various optical properties of these nanocrystals such as optical band gap energy, refractive index, dielectr...
Widespread use of ionizing radiation in medicine, industry, agriculture, education and research, the increasing production of nuclear waste and nuclear incidents, has exposed humans and organisms to this radiation. Despite the benefits of ionizing radiation, these beams can cause serious damage to living systems. Hence, the need for radiation protection actions requires accurate, fast, inexpens...
In this paper, digital signal processing for precise gamma ray spectroscopy is presented. The basis of this system is a 14bit waveform digitizer which samples the output of pre-amplifier signals directly. The advantages and limitations of the digital spectrometer compared with analog spectrometer has been tested and analyzed from precise gamma ray spectroscopy point of view. The results shows t...
background: the earlier atomic bomb explosion in hiroshima and nagasaki, and three worth mentioning nuclear accidents - detonation at fukushima daiichi nuclear plant, chernobyl nuclear fallout and an accident at three mile island nuclear power plant have made us more worried about the secure exploitation of nuclear energy. the central focus of this paper is to review radiation-mediated health e...
Background: The earlier Atomic Bomb explosion in Hiroshima and Nagasaki, and three worth mentioning nuclear accidents - detonation at Fukushima Daiichi nuclear plant, Chernobyl nuclear fallout and an accident at Three Mile Island nuclear power plant have made us more worried about the secure exploitation of nuclear energy. The central focus of this paper is to review radiation-mediated health e...
the currently reactor wreckage in fukushima raised the following important questions: is our knowledge of the possible dangers of ionizing radiation sufficient to warrant special action? what is the role of the medical community in technical radiation accidents from windscale to fukushima? what is the role of the medical community in terrorist radiation attacks? are we prepared for those challe...
Introduction: Ionizing radiation in medical imaging is one of the dominant sources of exposure, and correct knowledge of radiation protection, affects staff safety behaviors during procedures. This study aimed to assess the radiation protection Knowledge, Attitude and Practice (KAP) amongst nuclear medicine centers' staff in Iran. Methods: To evaluate the...
today, nuclear medicine has rapidly been developed so that in some cases, plays a unique role in diagnosis but unfortunalty in spite of diagnostic and therapeutic advantages, the term “nuclear” can induce worries in patients and society. in this article, base on new documents, we intend to show that this worries has no scientific basis. to produce a realistic view, regarding to radiation protec...
isotopic and nuclear techniques play an important role in food and agriculture, health and industry. in the agricultural sciences and food technology sectors, recent research has elucidated the new potential application of radiation for microbial decontamination, food preservation, improve the nutritional quality of foods and effectively utilise its potential as human food or animal feed. the...
