© Published under licence by IOP Publishing Ltd.This approach to assessing the uncertainty of measurements of sample activity was developed taking into account the requirements of the laboratory for dosimetry of incorporated radionuclides within the framework of the Methodology for measuring the activity of uranium isotopes by the spectrometric method after extraction-chromatographic isolation from urine samples. A detailed analysis of the sources of uncertainties in the activity of the sample was carried out: the uncertainty of the chemical yield, the uncertainties in the measurements of the activity of the sample, the working radioactive solution (WRS), and the uncertainty in the volume. All uncertainties are divided into two types: type A and type B. Estimation of measurement uncertainty is based on a model approach. The procedure for estimating the uncertainty of the activity of the sample was successfully verified using the specialized software GUM Workbench Pro during their construction.
