Stepping forward towards the quest of high throughput radiation marker, the present study looks for a common signature on comparison of NMR based urine metabolomics post whole body or partial irradiation. Different group of animals were exposed to 10 Gy whole body or partial radiation. Irradiated group were clustered apart from controls; showed similar pattern on radiation exposure irrespective of whole body or cranial and identified taurine, citrate as common metabolites in whole body and partial radiation groups. The similar pattern observed post partial or whole body irradiation further confirm these metabolites as potent markers for radiation exposure.
