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...

in this study, natural and artificial radioactivity concentration in agaricus bispora (nourished mushroom) and their composts, cantharellus cibarius and coprinus micaceuc (wild species) were determined. samples were collected from sahne and two kinds of wild mushroom species from songhor koliai township gardens all located in kermanshah province were collected. hpge gamma ray spectrometry syste...

indoor radon concentration (irc) is among the emerging environmental and health issues in republic of korea. due to lack of epidemiological studies and insufficient public awareness about radon, effective parameter ranking system is required to establish protocols for future field sampling and settlement construction. this research propose the irc parameter ranking system based on field measure...

the activity concentrations of 226ra, 232th, 40k and 137cs in water and sediment samples from hot springs of mahallat and  soil samples from their neighboring environs  have been determined using two high resolution high purity germanium (hpge) detectors with relative efficiencies 38.5% and 55%. the activity concentrations of 226ra, 232th, 40k and 137cs in sediment samples from hot spring donbe...

background: the most popular building materials are soil bricks and different types of stones. radon is released into ambient air from soil and stones due to ubiquitous uranium and radium in them, thus increasing the airborne radon concentration. the radioactivity in soils is related to radioactivity in the rocks from which the soil is formed. in the present investigation, the radon emanated fr...

abstract  background: the essential constituents of cements like lime, silica and alumina are derived from earth’s crust in which radioactive elements like uranium, thorium etc are also present in varying amounts almost everywhere. these two elements are considered as the parent elements of uranium and thorium radioactive decay series in which radon and thoron are produced respectively as decay...

introduction: one of the sources of natural occurring radiation was soils. the purpose of article was to determine soil pollution by radiation absorbed dose rate, radium equivalent activity, external hazard index, annual gonad dose equivalent and annual effective dose equivalent. methods & materials: the soil samples was located in chahbahar city in blouchestan of iran, was chosen for studying ...
