Download Orinoco ventuari region unblocking netflix 







The radioactivity levels were determined by orinoco ventuari region unblocking netflix of a gamma-ray spectroscopy system using a hyper-pure germanium detector in a low-background configuration. Particle size distribution and total organic matter content were also determined. Activity concentrations of Cs were lower than the detection limit of the analytical technique 0. The results suggest that orinoco ventuari region unblocking netflix variation of grain-size distribution is one of the most important factors influencing the spatial variations of 40K, Ra and Th in sediments along the Venezuelan coasts. In all sampling sites, average concentrations of 40K, Ra and Th were lower than the world average values. Activity concentrations of Ra, Th and 40K in coastal marine sediments along the Venezuelan coast could be considered to be low when compared with global average values, indicating that they are not apparently above of the range that might be considered normal or background. These results suggest that the studied sites do not pose any significant radiological threat to the population. The results attained in this study should be of considerable value as baseline data and background reference levels for Venezuelan coastlines.

The mean concentration of DOC was 3. The three rivers showed a similar temporal pattern in the concentrations of DOC, with higher DOC values during the increasing branch of the hydrograph due to wash-out processes of the organic material stored in soils. The mean concentration values of POC were 1. The inverse relationship found between the percentage in weight of the POC and the concentrations of TSS in the three rivers fits a logarithmic model, as it has been previously reported for other worldwide rivers.
