Anthropogenic radionuclides Cs and Pu isotopes originating from nuclear-weapons testing have been widely applied for dating sediments accumulated since the second half of the 20 th century. The Cs is the most popular radionuclide used as a chronostratigraphic marker. Basing on the assumption of its negligible post-depositional mobility three dates can be obtained for sediment profiles. The time horizons are associated with the first radiocaesium detection in the global fallout of , the maximum fallout in —64 and with the Chernobyl accident in UNSCEAR, These advantages make Pu peaks suitable for validating the Cs position in sediment profiles and in many circumstances they compensate the composed analytical procedure Hancock et al. In the future, the application of plutonium isotopes as sediment chronomarkers with their much longer half-life than Cs. In principle, sediment chronostratigraphy using heavy metals resembles dating with isotopes in the sense that it typically uses onset, maximum and emission cessation dates as markers of sediment horizons. Heavy metals can be used for sediment dating because the content of heavy metals in sediments accumulated during floods by a river is proportional to the degree of its pollution Ciszewski, However, heavy metals originate from almost every kind of human activity, only the rapid changes in the discharge of metals to river systems can be utilized for dating time horizons Hudson-Edwards et al.

Caesium 55 Cs , or radiocaesium , is a radioactive isotope of caesium which is formed as one of the more common fission products by the nuclear fission of uranium and other fissionable isotopes in nuclear reactors and nuclear weapons. Trace quantities also originate from natural fission of uranium It is among the most problematic of the short-to-medium-lifetime fission products because it easily moves and spreads in nature due to the high water solubility of caesium’s most common chemical compounds , which are salts.
Caesium has a half-life of about
Vertical marsh accretion is the process which counteracts subsidence and eustatic sea-level rise and prevents marsh deterioration, but, as in Louisiana’s salt marshes, the pattern, rate and variability are sufficiently complicated to defy simple prediction.

Radiocarbon dating is based on the continuous decay of the radioactive isotope of carbon, 14 C. Radiocarbon is incorporated into all living organisms in proportion to its concentration in the environment. When an organism dies, carbon is no longer incorporated into its tissues, but the radiocarbon present continues to decay at a known rate. We can date organic samples wood, charcoal, seeds, peat, sediments, plants, roots , shells and carbonates and also bones and teeth, ivory, antler.
The analyses are processed with a Leco CHN elemental analyzer.
Wine dating methods based on anthropogenic 14 C and Cs, as well as on the cosmogenic 14 C were studied with the aim to improve the accuracy and precision of the dating results. While the 14 C dating method has proved to be useful for dating young and old wines, the Cs has been effective for dating of wines originating around the Cs bomb-peak observed in A new method was developed for simultaneous 14 C and Cs dating of wines, which helped to distinguish wines originating before or after the bomb peak.
While the 14 C dating method is always destructive one, the Cs method may use a radiochemical separation of cesium from wine samples when better precision of results is required, but it can be also a nondestructive one with direct gamma-spectrometry of wine samples, especially those that are very rare. Abstract Wine dating methods based on anthropogenic 14 C and Cs, as well as on the cosmogenic 14 C were studied with the aim to improve the accuracy and precision of the dating results.

The sediment samples were collected using dry ice and liquid nitrogen freezing methods. The sediments of these lakes are annually laminated. A clear maximum concentration of Cs and , Pu was found in sediment layers formed during —, the years of maximum fallout, and the middle of the ‘s can be estimated from the Cs and , Pu profiles. The vertical distribution was similar for Cs and , Pu in the lakes investigated. A slight migration of , Pu and Cs was found and the migration of Cs seems to be higher than that of , Pu.

Abstract: The water quality of Dianchi Lake declines quickly and the eutrophication is getting serious. To identify the internal pollution load of Dianchi Lake it is necessary to evaluate its sediment accumulation. Sedimentation rates of Dianchi Lake are determined by Cs dating. However, Cs vertical distribution in sediment cores of Dianchi Lake has special characteristics because Dianchi Lake is located on the southeast of the Qinghai-Tibet Plateau, the Kunming quasi-stationary front is over the borders of Yunnan and Guizhou where the specific precipitation is distributed.
Besides , and Cs marks can be determined in sediment cores, a Cs mark of representing the major period of Cs released from China unclear test can be determined and used for an auxiliary dating mark. Meanwhile Dianchi Lake is divided into seven sections based on the water depth, basin topography, hydrological features and supplies of silt and the lakebed area of each section is calculated.
