Radioactivity level and the measurement of soil gas radon concentration in Dikili geothermal area, Turkey
Background: The natural radioactivity level and the radon concentration of soil were measured at four important geothermal area located in Dikili geothermal region, Turkey. Materials and Methods: The natural radionuclide content of soil samples were measured by NaI(Tl) gamma spectrometer system and the soil radon concentration were determined using Kodak-Pethe LR-115 Type II Solid State Nuclear...
متن کاملEstimation of soil moisture using optical, thermal and radar Remote Sensing )Case Study: South of Tehran(
Traditional methods of field measurement of soil moisture in addition to the difficulty, the need for manpower and money and fail to take place on a large scale to be able to show moisture. Therefore, remote sensing has become a widespread use .Landsat 8 satellite data and Sentinel-1 radar satellite from Tehran were provided. 72 soil samples were taken at the same time by satellite passing from...
متن کاملCorrections for measurements of tritium in subterranean vapor using silica gel.
Hazardous contaminants buried within vadose zones can accumulate in soil gas. The concentrations and spatial extent of these contaminants are measured to evaluate potential transport to groundwater for public risk evaluation. Tritium is an important contaminant found and monitored for in vadose zones across numerous sites within the US nuclear weapons complex, including Los Alamos National Labo...
متن کاملUse of Soil-Gas Helium Concentrations for Earthquake Prediction: Limitations Imposed by Diurnal Variation
The diurnal variations in soil-gas helium concentration have been monitored at depths of 0.5-2.0 m in three localities in Colorado, Wyoming, and C•lifornia.'Bar•metric p e•su TM, air temperature, wind speed, soil temperature and moisture, relative humidity, and precipitation were also measured. The helium variation below a 1-m sampling depth usually did not exceed the analytical sensitivity of ...
متن کاملDetermination of I/I isotope ratios in liquid solutions and environmental soil samples by ICP-MS with hexapole collision cell
The determination of I in environmental samples at ultratrace levels is very difficult by ICP-MS due to a high noise caused by Xe impurities in argon plasma gas (interference of Xe), possible IH2 1 interference and an insufficient abundance ratio sensitivity of the ICP mass spectrometer for I/I isotope ratio measurement. A sensitive, powerful and fast analytical technique for iodine isotope rat...
