Dary-to-day variation of urine 90Sr may produce error in the assessment of body 90Sr by urinalysis. Based on the good correlation between urine 90Sr and Ca, the range of the day-to-day variation of urine 90Sr was inferred from that of calcium, which was obtained from the analysis of about 50 to 100 urine samples per person in seven volunteers. From the frequency dstribution curves of urine calcium, it was concluded that 90per cent of the daily urine 90Sr would be involved in the range from 0.4 to 2.0 times the mean value. Therefore, if the assessment of body 90Sr is made from only one urinary excretion level, the estimated body burden will probably be in the range between 0.4 and 2 times the correct value.
