Gamma-ray detection has an important role in the enhancement the nuclear safety and provides a proper environment for applications of nuclear radiation. To reduce the risk of exposure, aerial gamma survey is commonly used as an advantage of the distance between the detection system and the radiation sources. One of the most important issues in aerial gamma survey is the detection noise. Various...
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...
The detection of radioactive target is becoming more important recently in public safety and national security. By using the physical law for nuclear radiation isotopes, this chapter proposes a statistical method for wireless sensor network data to detect and locate a hidden nuclear target in a large study area. The method assumes multiple radiation detectors have been used as sensor nodes in a...
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...
Background: The increasing prevalence of thyroid cancer among the survivors of atomic bomb attacks in Japan, nuclear fallout in the Marshall Islands, and Chernobyl nuclear power plant accident indicate a strong relationship between nuclear radiation and the occurrence of thyroid cancer. Materials and Methods: Systematic researches were conducted in the medical database of the American National ...
We have just concluded the study of radiation interaction with matter in which the basic mechanisms of charged particle, neutron and gamma interactions were discussed separately. A topic which makes use of all this information is the general problem of detection of nuclear radiation detection. Although this subject properly belongs to a course dealing with experimental aspects of applied nuclea...
Background & Objective: In the recent years, nuclear medicine has enjoyed remarkable growth thanks to such novel technologies as SPECT-CT and PET, which are utilized for the recognition of new detectable molecules and radiopharmaceutical medicines. Therefore, the current regulations on radiation protection require revision. Namazi Hospital of Shiraz is one of the first nuclear medicine center...
background: the aim of the study was to analyze the effective dose record of occupationally exposed radiation workers at bahawalpur institute of nuclear medicine and oncology department. materials and methods: annual effective doses of occupationally exposed workers were measured by film badge dosimetry by sending the dosimeters to radiation dosimetry laboratory (rdl), pakistan institute of nuc...
Introduction: Medical workers in the departments of radiology, computed tomography, nuclear medicine, and radiotherapy are always exposed to ionizing radiations. Complete blood count (CBC) test is commonly used to monitor the health of radiation workers. The aim of this study was to evaluate the hematological parameters of radiation workers of Isfahan, Iran, and reveal...
