Its specific activity is very low ~3.4×10 -7 Ci/g. The half-life of uranium-238 is 4.468 billion years. Of particular interest to archaeology are the long-lived daughters of 238 U (234 U and 230 Th, with half-lives of 245 and 75.7 ky, respectively) and the long-lived 231 Pa daughter (with a half-life of 32.7 ky) of 235U. 238 U : Half-life: Boson, 92p 146n: 4.471080669711×10 9 y: Spin 0 Parity 1: Show Decay Modes: Show Ultimate Decay Products The half-life of uranium 238 is of 4.5 billion years, while uranium 235 has a half-life of ‘only’ 700 million years. Though both isotopes were at the time of Earth formation equally abundant, natural uranium today consists today of 99.3% uranium 238 and only 0.70% uranium 235. The nuclei of uranium 235 and 238 are, along with those of thorium 232, Se hela listan på answersingenesis.org Since U-238 has a half-life of 4.5 billion years, it takes that amount of time for half of the original U-238 to decay into Pb-206.
