Determine Anzali lagoon sediment age based on Cesium-137

Abstract

From descending sedimentation rate viewpoint, accumulation of sediments in Anzali lagoon may be accompanies with rising water level in Anzali lagoon and descending the depth of the lagoon. Thus getting knowledge about the rate and the degree of sedimentation in lagoon can provide planners with useful approaches. Cesium-137 is an artificial Radionuclide with Gamma rays and half- life of 2/30 years which is produced as a by-product resulting from nuclear experiments of previous decades and released in stratosphere. Considering the high-powered of this approach in accuracy of assessment and easiness of data collecting, it has been used in surveying the age of sedimentation in Anzali lagoon.
