—Dr Dworkin is correct in stating that our dosimetry method has not previously been applied in an epidemiological context. However, the methods used to determine the doses in our study are based on mathematical models of radionuclides that have evolved over many years. In particular, the transport of131I, the principal source of exposure to the thyroid, has been well established and validated. The unique aspect of our method is that it incorporates information that is based on the ability of individuals to recall residence history, diet, and lifestyle information 30 years after it occurred. The most important data reported for a specific time period consisted of three facts: (1) the individual's residence, (2) whether fresh milk was consumed, and (3) whether the milk came from a commercial dairy or a family cow. We strongly believe that the subjects' parents were able to provide this information accurately.
