The accuracy of measuring the activity of Lu is crucial for calibrating the instruments employed in clinical applications. To support the measurements of Lu solution, the existing TDCR-Čerenkov method has been extended for this nuclide. The contribution of β and γ transitions from Lu was taken into account in the extended method. Finally, the results obtained using this method, with an uncertainty of 0.62%, were found to be in good agreement with that derived from liquid scintillation counting.
