Abstract

People have always been exposed to radiation and it is important to determine this radiation dose for radioactive contamination. The main source for this radiation is from earth and is can change with the geological structure. Isparta is an interesting area as it is Angle connects the Aegean-West Anatolian extensional section and it is bordered by two major fault zones. Thus radiation dose have been measured in vitro (in situ) in this area. The measurement has been performed using gamma spectrometer (GF Instruments) fitted with an NaI(Tl) scintillator detector. The spectrum can separate gamma rays due to the 238 U, 234 Th and 40 K and measure activity. From the in vitro measurements of radioactivity and absorbed dose, the annual effective dose (E d ) and radium equivalent activities (Ra eq ) were also obtained.

Natural Radiation Measurement in Some Soil Samples from Basra oil field, IRAQ State

“…leads to accumulation of sediments Inside the oil equipment in different forms, containing radionuclides that are more concentrated by increasing the accumulation of those sediments which lead to the reduction of oil production over time, which requires to cleaning of the equipment periodically and continuously, which leads exposure of radiation risk to the workers and pollution of land surrounding the oil fields and the environment if they are not handled safely and uncontrolled to prevent their spread [3]. In the literature, some researchers have carried out a series of studies to identify and evaluate 226 Ra, 232 Th and 40 K activity concentrations in environmental samples such as stone, soil in various parts of the world [4][5][6][7][8][9][10][11][12][13][14][15][16].…”

Production of Barite and Boroncarbide Doped Radiation Shielding Polymer Composite Panels

“…Protection from these radiation is based on applying three fundamental strategies: [2,6] • Minimize the time spent near radiation sources,…”

“…where I is the intensity of radioactive beam after passing through an absorber, I 0 is the initial intensity of the beam, without the absorber, µ is linear attenuation coefficient, e is base of natural logarithms and x is thickness of the absorber sample [2,6,8].…”

Monte Carlo simulations study on gamma ray–neutron shielding characteristics for vinyl ester composites

“…With the rapid development of technology, the utilization of radiation increased sharply and thus its measurement and hazardous effect were studied. [1][2][3][4][5][6][7][8][9][10] Obviously, this requires radiation protection, and consequently, the use of the shielding materials increases due to the raising the risks of radiation on human health and the environment. However, numerous studies were carried out about shielding qualities of different materials such as concrete, lead-based materials, and glasses, and also polymers, [6, the toxicity and high emission of the greenhouse gases of the lead, and concrete respectively restricted the uses of these traditional shielding materials.…”
