The iodine content of Total Diet food composites was measured using neutron activation analysis. The interfering element chlorine was separated using a modified combustion and gas phase procedure. The average recovery was 94.8% (standard deviation 2.9) for the 10 matrices that were tested. In addition, iodine was measured in National Bureau of Standards Standard Reference Materials, which have no certified values for this element. Preliminary findings of iodine content of adult Total Diet market baskets collected during Fiscal Year 1980 in different regions of the United States ranged from 292 to 901 micrograms/day for a 2900 kcal intake.
使用中子活化分析法测量了总膳食食品组合的碘含量。采用改良的燃烧和气相程序分离干扰元素氯。在所测试的10种基质中，平均回收率为94.8%（标准偏差为2.9）。此外，还对美国国家标准局的标准参考物质进行了碘含量测量，这些物质没有该元素的认证值。1980财政年度在美国不同地区收集的成人总膳食市场篮子碘含量的初步调查结果显示，对于2900千卡的摄入量，碘含量范围为每天292至901微克。
