Abstract

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.
