The radiological characterization of radioactive waste and effluents requires the measurement of many radionuclides, including 90Sr. The usual methods for 90Sr analysis are efficient but they are relatively long and require the use of toxic products such as fuming nitric acid and scintillation cocktails. This thesis work consisted in developing new analytical procedures for 90Sr analysis, in particular new separation methods. A first method based on successive selective precipitations was optimized using design of experiments methodology and speciation modelling. Fuming nitric acid was replaced by concentrated nitric acid at 69 % while preserving the separation selectivity between Sr and Ca, and an understanding of the mechanisms involved i...
