Radioactive isotopes are traditionally quantified by means of radioactivity counting techniques (a, b ,y). These techniques often require extensive matrix separation and sample purification methods before unequivocal identification of specific isotopes and their relative abundance is possible. Counting times become very protracted when the half-life of the target analyte is very long or the concentration of the analyte is very low, e.g., environmental and bioassay measurement, which means that rapid response is difficult.
