| Abstract: | Iodine-131 in urine samples from 15 Japanese subjects was determined during the period 4 to 29 May 1986. In a male adult, the peak concentration (3.3 Bq dm−3) was observed on 9 May, the levels decreasing thereafter to less than the detection limit by 29 May. The highest concentration observed was 7.6 Bq dm−3 in a female adult. The urinary concentrations in the 11 adult subjects appeared to correlate with consumption of green leafy vegetables and milk. In four children, 6 to 14 years old, 131I concentrations in urine were generally higher than those of the adults. The major source of 131I intake was confirmed to be from vegetables, not milk. |
