Iodine nutrition in the Chernobyl area before and after the nuclear accident

Reports from 1950 to 1960 suggest that goiter was frequent in the Chernobyl area and vigorous efforts were undertaken to distribute iodine supplements. There resulted enthusiastic reports stating that endemic goiter was no longer a problem. During the 1970s, the distribution of iodized salt became undependable and by 1980, goiter incidence was reported to have increased. Four to ten years after the Chernobyl nuclear accident, severe iodine deficiency was unusual but goiter by ultrasound measurement was found in more than 35% of the children. Unusual thyroid cancer appeared and its prevalence continues to increase.
