| Abstract: | The radioisotope silicon-32, an irreplaceable dating tool, can be used to determinethe age of water ranging between 50 and 1000 years old, because its value of half-life lies between the common environmental isotopes 3H and 14C. In this paper are presented the origin of 32Si,its distribution pattern in hydrosphere, its controlling factors,its testing methods and its applications to oceanography, glaciology and hydrogeology. |
