Mineral Radioactivity Promotes Organic Complexity on Rocky Planets
The Role of Irradiation: Irradiation is widely invoked as a mechanism by which simple carbonbearing molecules may be polymerised or otherwise reacted to form progressively more complex molecules that could ultimately synthesize life [1]. In our solar system, cosmic irradiation has been invoked as a source of complex molecules on the Galilean satellites, and on Titan, Pluto, Uranus and Neptune. ...

15 صفحه اولstudy of khraghan (ghazvin) mineral springs
one of the natural resources in our country is mineral water that hasnot been used as it should, and can be found allover the country. kharaqhan hot water is located by the ghazvin-hamedan road. this spring is being used in a very primitive way and is the subject of this investigation. the analyses were carried on the field and in the laboratory by standard methods and the results are shown in ...
متن کاملRadiological aspects of some Egyptian thermo-mineral springs.
In Egypt, nineteen water springs with temperatures exceeding 35 degrees C, which can be considered thermal waters, were reported. The radiological aspects of thermal water in three northern regions of Egypt (Gulf of Suez, Cairo, and Bahariya Oasis) were investigated. The activity concentrations of natural radionuclides of 226Ra, 40K, total uranium and 210Pb (210Po) in water samples were determi...
متن کاملRadioactivity Concentration in Sediment and Water Samples of Hot Springs of Mahallat and Soil Samples of Their Neighboring Environs
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, 23...
