In order to apply to a tracer experiment, an analytical method for ^<210>Pb in animal organs and excreta was studied, and a convenient method was established as follows : The sample was digested at 150-170°, using conc. HNO_8 and 60 % HClO_4. The separation of ^<210>Pb from ^<210>Bi and ^<210>Po, the daughter nuclides of ^<210>Pb, was accomplished by passing 1 N HCl solution of the digested sample through a column of anion-exchange resin, and by eluting ^<210>Pb with 0.1 N HCl. The β-activity of ^<210>Pb was measured using a liquid scintillation counter. In this method, the radiochemical recovery of ^<210>Pb from biological samples was quantitative, and the counting efficiency of the β-activity of ^<210>Pb was 37.1%. Furthermore, the procedure of this method does not require a long time and many samples can be treated in a short time.
