Radioactive dating in biology

radioactive dating in biology - More in these related articles:Dating (geochronology): carbon-14 dating and other cosmogenic methods in geology, determining a chronology or calendar of events in the history of earth, using to a large degree the evidence of organic evolution in the sedimentary rocks accumulated through geologic time in marine and continental environments. The half-life of the 14c isotope is 5,730 years, adjusted from 5,568 years originally calculated in the 1940s; the upper limit of dating is in the region of 55-60,000 years, after which the amount of 14c is negligible (3). Dating - student encyclopedia (ages 11 and up)scientists in the fields of geology, climatology, anthropology, and archaeology can answer many questions about the past through a technique called radiocarbon, or carbon-14, dating. Practical uses of radiocarbon dating in climate science covers similar examples to the archaeological examples seen above (changes in fauna and vegetation for example) but it is fundamental in other areas too (12).
