Section Summary

> The HTDS is a scientific study conducted to determine whether there was an increased risk of developing thyroid disease among people exposed to iodine-131 from Hanford.
> The HTDS data show that the risks of thyroid disease were about the same regardless of the radiation doses people received.
> The findings mean that if there is an increased risk of thyroid disease from exposure to Hanford's iodine-131, it is probably too small to observe using the best epidemiologic methods available.
> Researchers found that the occurrence of thyroid disease in the study group was about the same as has been reported for other populations.
