1. Abstract The analysis of radionuclides is complex, with high economic and time costs. For this reason, there is a need to develop new methods and strategies to reduce these costs. One important group in the analysis of radionuclides is the actinid

Classical vs. evolved quenching parameters and procedures in scintillation measurements: The importance of ionization quenching

Autor: H. Bagán, José Ramón Flecha García, A. Tarancón, Gemma Rauret

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 592:361-368

The quenching parameters used to model detection efficiency variations in scintillation measurements have not evolved since the decade of 1970s. Meanwhile, computer capabilities have increased enormously and ionization quenching has appeared in pract

Comparing Continental Carbonates with Other Materials in Dating a Paleolake

Autor: Gemma Rauret, J. F. Mestres, José Ramón Flecha García

Publikováno v: Radiocarbon. 34:619-625

We have studied the application of carbonates and organic matter to the radiocarbon dating of a paleolake. The results show a systematic apparent age shift of these materials with respect to contemporary wood. The apparent age of carbonates is eviden
