| Research Abstract |
Radiological dose assessment using a biological sample is an effective technique for estimating internal radiation exposure. Among such samples, urine is one of the suitable biological materials for screening the level of internal radiation exposure during radiation or nuclear emergencies, because it can be easily sampled in the field. Uranium in a urine sample was separated from mineral components using anion exchange group-containing porous-polymeric-disk-packed cartridge. The time required to accomplish the procedure from conditioning to washing of the cartridge was 20 minutes. A simple and rapid removal of mineral components with high concentrations was demonstrated, while the ultratrace amount of U remained adsorbed on the cartridge.
