The activity concentrations of 40K, 238U, 232Th and 137Cs were measured using gamma spectrometric method in different food chain samples from Serb Belgrade environment during the periods May-June 2007 and May-June 2008 year. Relatively high activities of 40K and 137Cs were detected in the soil. These results indicate that 137Cs is present in Belgrade environment even 20 years after nuclear acci...
The fundamental goal of this study is to measure the level radioactivity in soil area around Al-Hadbaa cement plant, also evaluate radiological hazard radionuclide, gamma-spectroscopy with an HPGe detector crystal diameter 70.6 mm and length 70 has been used estimate specific activity natural radionuclides 226Ra, 232Th, 40K, artificial 137Cs fifteen samples collected. results show that average ...
background: a field study on the transfer of primordial radionuclides 238u, 232th, 40k and fallout radionuclides 210po in different plant species in tropical forest of western ghats environment is presented. material and methods: the top storey, second storey, shrubs and epiphytic plant species were chosen and concentration of these radionuclides in plant and soil were measured by employing gam...
Fertilizers based on NPK are reported to have large concentrations of naturally occurring radionuclides. Hence, fertilizers usage can elevate the concentration natural radioisotopes in soil and groundwater leading a higher 40K, 238U 232Th crops grown these fields. In last few years, surge is witnessed organic farming methods due consumer demand. this study, 40K,232Th 226Ra compared between conv...
abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...
Agricultural researchers in many countries investigate radiological risks soil and crops because it concerns human health. In addition, they also study heavy metal pollution plants cultivated for ecological safety. This aims to analyze the activity concentrations of radionuclides metals corn Küçük Menderes Basin (Izmir, Turkey) – which is enriched with phosphatic fertilizers. We collected sampl...
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
