Popis:	A sequential analysis procedure for urine samples was developed and validated focusing on 210Po, natural uranium, and thorium radioisotopes. The amount of sample for analysis and counting time were estimated to meet the criteria of minimum detectable activity, which was referenced from the ICRP. The analysis procedure was modified via sequential extraction and was validated using certified reference samples. The time required for sample preparation by this method was compared with those by other methods. Forty-four urine samples collected from participants were analyzed, and the results were compared with those obtained in other studies.
