本文为解决７～１４岁在校小学生的补碘问题，采用由军事医学科学院毒物药物研究所提供的碘砖，选择北京市轻病区，三个受试单位。根据儿童的生理需要量和碘砖投放热水后每天平均释碘量，规定学生每人每日饮热碘水３００—４００毫升（约可补充２００—３００微克碘），饮碘水后学生平均尿碘排出量明显增加，三所小学学生饮水后不同时间平均尿碘排出量与饮水前相比较；差别非常显著。用本法补碘，只需将碘砖投入饮水筒内，即可以在日常饮水的同时达到补碘的目的。此方法可靠、经济、简便，符合中央提出的“以较少的投入，换来几亿人民的健康”的防治思想，可以作为一种对小学生集中补碘的措施，有一定的推广价值。
In order to solve the problem of iodine supplement in pupils aged 7 ~ 14 years old, I chose iodine bricks provided by Institute of Toxicology and Pharmacology, Academy of Military Medical Sciences, and selected three light units in Beijing. According to the physiological needs of children and iodine bricks after the release of hot water on average the amount of iodine per day, the provisions of the daily intake of hot water iodine 300-300 ml (about 200-300 micrograms of iodine supplement), after drinking iodine average students Urinary iodine emissions increased significantly, three primary school students at different times after drinking water urinary iodine emissions compared with the former; the difference is very significant. Iodine with this method, just put iodine bricks into the drinking tube, which can be in the daily drinking water to achieve the purpose of iodine. This method is reliable, economical and simple, and meets the prevention and control ideology of “putting less investment in exchange for the health of hundreds of millions of people” put forward by the Central Government. It can be used as a measure of primary school students to supplement iodine in a certain amount.
