In the present work, we describe metabolomics for X-ray irradiation biodosimetry in a mouse model. To analyze the large number of metabolomes, we employed the high-throughput NMR technique. The results show that the X-ray exposure yields distinct urine metabolomic phenotypes in mice. Furthermore, the phenotype is dose-dependent and time-dependent. Based on the understanding acquired in this work, we will be in a position to initiate measurements of metabolomics "fingerprints" in humans who were exposed to radiation.
