Coprecipitation technique as a new approach of using solid-state scintillation

Abstract

In this paper, the coprecipitation methods of selected radionuclides in connection with solid-state scintillation counting were explored. The calcium phosphate co-precipitation method exhibited best results from all investigated methods reaching almost absolute detection efficiencies for selected actinides and more than 60% for Sr/Y-90. The linear response of the measurement was in the range of 0.4 to 411.5 Bq for alpha/beta separation mode, respective 0.4 to 2000 Bq nuclear counting (high activity mode). Computed and optimized MDA values exhibited better results in comparison with previous works.
