WebMar 23, 2024 · One format involves calculating a mass amount of the original isotope. Using the equation below, we can determine how much of the original isotope remains after a certain interval of time. how much mass remains = 1 2n(original mass) n is the number of half-lives. Example 5.7.1. WebRadioactive C-14 has a half-life of about 5,000 years. If a fossil is only about 6% as radioactive as expected for living tissue of the same mass, the age of the fossil is about: Webof the neutron energy flux density spectrum. The Cf-252 fission neutron spectrum and the use of Cf-252 sources to examine neutron cross-sections by neutron spectrum measurements was discussed. The results indicate that errors in some cross-sections are detectable which are considerably smaller than the accuracy of direct cross-section ... idw ps 960
