Hayes et al. (2002) have presented an “EPR model” for separating internal 90Sr doses from external gamma-ray doses in teeth and propose application to the “Techa River population.” Dose reconstruction for members of the Extended Techa River Cohort (ETRC) has been a focus of our studies for many years (Degteva et al. 2000a,b; 2002), and it is disappointing that Hayes et al. did not discuss this issue with us. It is our opinion that the model proposed by Hayes et al. cannot be regarded as applicable, because it is based on unrealistic assumptions. Their “simplified” model is far from simple, except for its unrealistic characterization of the source configuration of 90Sr deposited within the tooth. Our objections to this paper are numerous, and only the more important are given.
