BACKGROUND The radiological quality of (226)Ra, (232)Th and (40)K in some samples of water resources collected in Anarak-Khour a desertic area, Iran has been measured by direct gamma ray spectroscopy using high purity germanium detector in this paper. RESULT The concentration ranged from ≤0.5 to 9701 mBq/L for (226)Ra; ≤0.2 to 28215 mBq/L for (232)Th and < MDA to 10332 mBq/L for (40)K. The ra...
this study was conducted to determine the radioactivity concentration in soil samples of anarak-khour district located at central iran. 48 soil samples from a depth of 10-15 cm were taken from seven different sites for monitoring. the radioactivity concentration of 238u, 232th, 137cs and 40k in soil samples was determined, using a high resolution (hpge detector, p-type) γ-spectrometry by detect...

The Anarak ophiolite, with E-W trending, located at north of Anarak. In addition to the gabbros in Anarak ophiolite sequence, intrusion of metasomatized gabbros injected into the ophiolite of Anarak in the form of stocks and dykes. metasomatized gabbros are younger than Anarak ophiolite and older than Anarak metamorphic assemblage and contain diopside, augite, actinolitic hornblende, actinolite...
Since the most important climatic parameter affecting sugar beet cultivation is the temperature, we carried out this research considering climatic elements such as temperature, precipitation and freezing days in relation to autumn sugar beet planting. Daily temperatures of selected stations in a period of 10 years (2005-2015) has been used for agroclimatic analysis. In order to evaluate that, t...
In the upper Proterozoic Anarak ophiolite, the marbles are present and havr excellent exposures in different areas. Their best exposure is in southern slope of Chah-Gorbeh mountain (Chah-Mahdi valley). In the field, marbles have massive and dike like exposures. Petrographic studies and geochemistry of minerals show that marbles consist of carbonate (calcite), garnet (andradite), clinopyroxene (...
Eocene volcanic rocks of north Anarak area are as scattered as masses. These rocks cross the Anarak schists and Ashin-Zavar ophiolites but had not metamorphosed them. Their outcrops follow the direction of within the area faults. Mineralogicaly, these rocks are limited in composition from Andesi-Basalt and Andesite to Dacite. These rocks have phenocrysts of amphibole and plagioclase in microcry...
geographical bases have significant function in human settlements in terms of distribution and sustainability. thisstudy attempted to provide an insight into the role of geographical bases in rural settlement distribution in arid areas.accordingly, this study was done in the rural area of khour-biabanak, naein city in esfahan province. themethodology was that of a correlative research, to reali...
In this study, the distribution coefficient of Nickel on Anarak nuclear repository was studied considering effects contaminant concentration, soil particle size, and soil/solution ratio. For purpose, two experiments were designed. The sample collected from inside trench Nuclear Repository by channel method its characteristics determined using ASTM method. batch employed while different concentr...
