Physical stopping rate factors

It is well known that anthropogenic radionuclides such as radiocaesium and plutonium together with natural Pb are accumulated in sediments and can be used for the dating/growth rate determination of the sediments. The flux of these radionuclides depends on factors, such as physical and chemical properties, biological factors etc,. Water dams along rivers will stop the water flow and might act as effective traps by sedimentation processes and accumulate material that otherwise would be transported to the sea. 

Automation In data acquisition and treatment can be aimed at a variety of objectives inherent in the above-mentioned factors. It should be pointed out that physical and physico-chemical kinetic factors play a decisive role in the reduction of human Intervention. The acquisition of data at a high rate imposed by the technique Itself (e.g. picosecond spectroscopy [19]) or by the system Investigated (e.g. meaurements of rates of reactions with half-lives of the order of a few milliseconds by the stopped-flow methodology [20,21]) demand the use of a computerized system without which application of the particular spectroscopic technique or method would not be feasible. On the other hand, the so-called microprocessor-controlled spectroscopy , widely commercialized at present, broadens the scope and facilitates the operator s work by eliminating various sources of error.
