ABSTRACT:
Using storage phosphor recording media, two exposures are made of a sample containing two target substances tagged with different radiative emitters, for example 32-P and 35-S. The first exposure, image 1, is of the sample directly on the phosphor screen. The second exposure, image 2, is made with the appropriate absorption material between the sample and screen. Both images are captured. By using simultaneous equations isotope contributions of each label can be determined. Quantitative assessment of the contributions of the isotopes, and hence the target substances, are made by calculating isotope efficiencies both with and without the absorption filter.
