“…It was first detected in early 1950s peaking in early 1960s (Stefano et al, 1999;Mabit et al, 2014a) before the nuclear test ban treaty. However, it declined to very low levels in the mid-1970s.…”

“…On the other hand, if accumulation rates are low, the 210 Pb activity reduces rapidly with depth (Walling et al, 2002). The 210 Pb is useful in estimating the soil redistribution for up to 100 years (Zheng et al, 2006;Benmansour et al, 2014;Mabit et al, 2014a) a period longer than that of 137 Cs. Further, 210 Pb is useful in areas where low 137 Cs concentration is likely to pose a problem especially in the southern hemisphere (Porto et al, 2006;Shakhashiro and Mabit, 2011).…”

Soil erosion is one of the main soil degradation phenomena that threaten sustainable use of soil productivity thus affecting food security. In addition, it leads to reservoir storage capacity loss because of sedimentation. This not only affects water quantity but also water quality. Worldwide, annual loss in reservoir storage capacity due to sedimentation is 0.5 to 1%. Similarly, about 27% of land in Africa is largely degraded by erosion. As a result, there is need to minimize soil erosion and deposition through site specific estimation of soil erosion and deposition rates in the reservoirs. To achieve this, Fallout RadioNuclides (FRNs) are some of the methods in use. The most common radionuclides include; 137 Cs, 210 Pb and 7

“…Those sediment layers were dated by 210 Pb CRS model as 1973-1978and 1985-1989. Some discrepancies between 210 Pb CRS model dates and 137 Cs peak position could be explained as 137 Cs penetration to greater depth than expected from diffusion (Mabit et al, 2014). It can be influenced by combination of physical and biological mixing of newly accumulated sediments (O'Reilly et al, 2011), as well as by postdepositional migration in sediments (Appleby et al, 1991).…”

“…The CRS model assumes that the supply of 210 Pb ex to the accreting material is constant in time (Appleby and Olfield, 1978), the initial 210 Pb concentration in the sediments is variable, and the influx rate of sediment is variable (Goldberg, 1963 andAppleby andOldfield, 1978). When 210 Pb ex fluxes and sediment mass accumulation rate (MAR) are both constant, the CIC and CRS models converge to CF:CS model and the 210 Pb ex concentration follows an exponential decrease with mass depth (Mabit et al, 2014). 210 Pb dating depends on the accurate determination of the level of unsupported 210 Pb in a series of sediment samples, what is quite problematic because of sampling and analytical limitations (MacKenzie et al, 2011).…”

“…The CIC model is appropriate when initial activity of 210 Pb ex is constant and there is no mixing of surface sediments (MacKenzie et al, 2011 andMabit et al, 2014). The CRS model assumes that the supply of 210 Pb ex to the accreting material is constant in time (Appleby and Olfield, 1978), the initial 210 Pb concentration in the sediments is variable, and the influx rate of sediment is variable (Goldberg, 1963 andAppleby andOldfield, 1978).…”

Comparison of beta (LSC) and gamma (HPGe) spectrometric methods for lead-210 in chronological study

Abstract:The sediments of two lakes located in the Baltic Uplands, the western part of the East European Plain (East Lithuania and North East Poland), were studied. Activity concentration of Pb determination by LSC the methodology of lead separation based on the anion exchange resin in Cl -form (Eichrom) was used. Several steps of radiochemical procedures and respective parameters were investigated additionally. The optimized procedures for LSC method were used for case study with two lake cores. The activity concentration of 210 Pb in lake sediment samples based on both nuclear analytical techniques (LSC and HPGe) were compared. 210Pb dating of cores was performed according to Constant Rate of 210 Pb Supply (CRS) model with some modifications. Both techniques in the range of uncertainties gave similar results. From two considered lakes, the more eutrophic one exhibited higher sediment mass accumulation rate (MAR) values.

This study shows that the cosmogenic radionuclide beryllium‐7 can be used to track sediment movement through caves. The activities of beryllium‐7 and cesium‐137 were measured in two different karst settings at both surface and subsurface sites before and after storm runoff events. At one site, 7Be‐enriched sediment was detected up to 1.5 km along a stream conduit after a moderate storm event; however, the activity of 137Cs was too variable to show a meaningful pattern. The percentages of surface sediment that was found ranged from 0 to 52% along the entire 3 km cave stream and from 33 to 52% along the upper 1.5 km. At the other site, as much as 96% of the sediment initially discharged at the spring during a storm event was fresh surface material that had traveled into and through the cave stream. Moreover, during the 4 day runoff event, approximately 23% of the total suspended sediment flux was estimated to originate from surface erosion with 78% being reworked sediment from within the cave. The data in this study show that cosmogenic radionuclides with multiyear half‐lives are too long‐lived to track sediment origins in the caves; whereas, 7Be with a 53.2 day half‐life, can be used to track movement of sediment along cave streams.
