Radioactive elements in dating events and artifacts hittest dating sites in the net
As radioisotopes are identical chemically with stable isotopes of the same element, they can take the place of the latter in physiological processes.Moreover, because of their radioactivity, they can be readily traced even in minute quantities with such detection devices as gamma-ray spectrometers and proportional counters., used with radiographic scanning devices, is valuable for studying the anatomic structure of organs.Such radioisotopes as cobalt-60 and cesium-137 are widely used to treat cancer.
