Определение uranium- в Английский Язык Английский Язык словарь
uraniumspan>-235: An isotope of uranium, used for energy generation and in atomic weapons, containing one hundred and forty-three neutrons. It has a half-life of 7·038×108 years, whereupon it decays into thorium-231
uraniumspan>-234-uraniumspan>-238 dating: Method of age determination that makes use of the radioactive decay of uranium-238 to uranium-234; the method can be used for dating sediments from either a marine or a playa lake environment. Because this method is useful for the period 100,000-1.2 million years before the present, it helps in bridging the gap between the carbon-14 dating method and the potassium-argon dating method
uraniumspan>-thorium-lead dating: or common-lead dating Method of dating very old rocks by means of the amount of common lead they contain. Common lead is any lead from a rock or mineral that contains a large amount of lead and a small amount of the radioactive precursors of lead (i.e., the isotopes uranium-235, uranium-238, and thorium-232). By this method, the age of the Earth has been estimated to be 4.6 billion years. This figure is in good agreement with the age of meteorites and the age of the Moon as determined independently
