ABSTRACT
@#<b>Objective</b> To preliminarily study and establish a method for measurement of the transuranic nuclide <sup>241</sup>Am in fecal samples, and to provide technical support for internal radiation monitoring of staff. <b>Methods</b> Fecal samples were collected with a self-made stool sampler and treated with a self-made carbonization and ashing furnace. DGA resin was used to separate and purify <sup>241</sup>Am from fecal samples. With <sup>243</sup>Am as the tracer, the orthogonal method was used for condition optimization. <b>Results</b> The optimum conditions for separation and purification were the acidity of HNO<sub>3</sub> added into the column, 6 mol/L; column flow rate, 0.6 mL/min; and the volume of analytical solution,12 mL. The method based on inductively coupled plasma mass spectrometry showed a detection limit of 9.79×10<sup>−4</sup> Bq for <sup>241</sup>Am in fecal samples, which was satisfactory and feasible. <b>Conclusion</b> This method fills the vacancy of <sup>241</sup>Am measurement in fecal samples to some extent, which is of practical significance for internal radiation monitoring and protection for analysts.
