In this study, to assess the internal radiation dose in radiation emergencies, the variability of spot urine normalization methods is studied using 40K measurement results. The mean creatinine concentration and the mean 40K activity concentration in the spot urine samples studied were 139 mg dL-1 and 106 Bq kg-1, respectively. The results indicate that the 40K activity concentration method can be used to complement the method used for normalizing the creatinine concentration in spot urine in a radiological emergency.
