Liquid-scintillation-based anticoincidence counting of Co-60 and Pb-210.
The method of liquid-scintillation-based 4pibeta-gamma anticoincidence counting was employed to assay the radioactivity concentration of acid solutions containing radionuclides (60)Co and (210)Pb (in equilibrium with its daughters). The limiting factors on the accuracy for such activity measurements and suggestions for minimizing such factors are reported.
