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...
We study thorium-doped CaF2 crystals as a possible platform for optical spectroscopy of the (229)Th nuclear isomer transition. We anticipate two major sources of background signal that might cover the nuclear spectroscopy signal: VUV-photoluminescence, caused by the probe light, and radioluminescence, caused by the radioactive decay of (229)Th and its daughters. We find a rich photoluminescence...
■ ■ What are the motivations for working on extreme-ultraviolet technology today? The extreme-ultraviolet (XUV) spectral range is a largely unexplored frontier for high-resolution laser spectroscopy. Until very recently, no one thought it possible to have access to continuous-wave-like radiation in this spectral region. Now, with the convergence of ultrafast laser science, strongfield physics a...
Measurements of high-energy photons from cosmic sources of nuclear radiation through ESA's INTEGRAL mission have advanced our knowledge: new data with high spectral resolution showed that characteristic gamma-ray lines from radioactive decays occur throughout the Galaxy in its interstellar medium. Although the number of detected sources and often the significance of the astrophysical results re...
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, ...
ABSTRACT Background : The application of DU emanation for first time contaminated certain areas in the south west region of Iraq after the second Gulf war (1991). These contaminated areas were discovered in 1994. Radioactive contamination was detected using the nuclear enterprise PCM5/1 in soil samples collected from two regions near by grazing lands. This study was done for assessment of D...
introduction: occupational exposure to ionizing radiation due to medical activities (both diagnostic and therapeutic procedures) has increased sharply in recent years. among the occupationally exposed workers in these fields, those most affected by this increased exposure to ionizing radiation are nuclear medicine workers. in this study, annual average effective dose, annual collective effectiv...
objective: reporting some biological side effects with special attention to reproductive points which were seen after different experiments in laboratories of the plasma physics & nuclear fusion in atomic energy organization of iran. materials and methods: dosimeter analysis and interpretation of biological side effects of research studies in nuclear fusion laboratories. results: in the last 3 ...
When the first atomic structures of salt crystals were determined by the Braggs in 1912-1913, the analytical power of X-ray crystallography was immediately evident. Within a few decades the technique was being applied to the more complex molecules of chemistry and biology and is rightly regarded as the foundation stone of structural biology, a field that emerged in the 1950s when X-ray diffract...
