Dose rates and seasonal variations of U-238, Th-232, Ra-226 K-40 and Cs-137 radionuclides in soils along Thrace, Turkey
(Springer, 2014)
Concentrations of U-238, Th-232, Ra-226, K-40 and Cs-137 are measured in collected soil samples from various locations in the Thrace region of Turkey. The activity concentrations range from 12.82 to 101.75 Bq kg(-1) d.w. ...
Annual effective dose of naturally occurring radionuclides in soil and sediment
(Taylor & Francis Ltd, 2014)
In this study, the natural radioactivity level of soils and sediments due to the usage of fertilizers, particularly phosphate fertilizers, in agricultural lands of the Buyuk Menderes River Basin, Western Turkey, have been ...
A suggestion to radiological hazards characterization of Ra-226, Th-232, K-40 and Cs-137: spatial distribution modelling
(Elsevier Science Bv, 2018)
Spatial distribution modelling has been proposed to characterize the radiological hazards associated with concentration of natural Ra-226, Th-232, K-40 and artificial Cs-137 radionuclides in the nature. These elements have ...
Determination of radiation dose from patients undergoing Tc-99m Sestamibi nuclear cardiac imaging
(Springer, 2019)
To date, myocardial perfusion (MP) has been utilized to assess the adequacy of blood flow to the myocardium in order to determine the ischemic heart diseases. With the advent of SPECT/CT, MP became the most common investigation ...
Determination of indoor radon levels at campuses of uskudar and Okan Universities
(Springer, 2019)
Radon is the largest source of natural radiation all people exposed to. It can form in houses due to building materials or enters through cracks in walls, basement floors and with water used in bathroom showers and faucets. ...
Measurement of indoor radon concentration and annual effective dose estimation for a university campus in Istanbul
(Springer Heidelberg, 2019)
Radiation is a natural part of the environment that people interact continuously, and radon is one of the most important sources because of its abundance and mobility. Due to gas form, radon can reach and accumulate in ...
Descriptive statistics and risk assessment for the control of seasonal pollutant effects of Po-210 and Pb-210 in coastal waters (Canakkale, Turkey)
(Springer, 2018)
Po-210 is absorbed into the human body by seafood intake. Especially, mollusks and mussels are known to have much higher Po-210 concentration than fish among various other types of seafood and are consumed in large quantities ...
Electrical characteristics of Au/n-GaAs structures with thin and thick SiO2 dielectric layer
(Pleiades Publishing Inc, 2011)
The aim of this study, to explain effects of the SiO2 insulator layer thickness on the electrical properties of Au/n-GaAs Shottky barrier diodes (SBDs). Thin (60 ) and thick (250 ) SiO2 insulator layers were deposited on ...
Tuning of electronic structure, magnetic phase, and transition temperature in two-dimensional Cr-based Janus MXenes
(Amer Physical Soc, 2021)
Two-dimensional (2D) transition metal carbides and nitrides, called as MXenes, displaying astonishing properties are emerged as a new class of 2D layered materials. In this study, we have studied the structural, electronic, ...
