Naturally produced tritium provides the hydrological information with a valuable tool for tracing groundwater through the hydrologic cycle. These investgatigations have been carried out using both naturally produced and atomic bomb-produced tritium.
This analysis was done by using liquid scintillation counter, preceded by electrolytic enrichment.
In the shallow groundwater, tritium concentration vary from 5∼6 TR to a few hundreds, while in Case of deep groundwater, the value is slightly lower. This is due to older existence of deep groundwater, it will cause various groundwater disasters.
The above became clear as a result of investigations on tritium concentration used to forecast groundwater disaster.
