Silicates, coal and related solids from energy production

In this chapter the radioanalysis of silicates, particulate matter and (fly-) ash is considered. The fact that these materials are usually of a grain-like structure entails the necessity of further definition by some physical or chemical separation steps. Moreover distinctions have to be made between total and available concentrations and between surface and bulk-phenomena. Radioanalysis of these materials thus comprises elemental analysis and radiotracer experiments. (orig.)
