The Techa River Dosimetry System (TRDS) has been developed to provide estimates of doses received by approximately 30,000 members of the Extended Techa River Cohort (ETRC). Members of the ETRC were exposed beginning in 1949 to significant levels of external and internal (mainly from 90Sr) dose, but at low-to-moderate dose rates. Members of this cohort are being studied in an effort to test the hypothesis that exposure at low-to-moderate dose rates has the same effectiveness as exposure at high dose rates. The current version of the TRDS is known as TRDS-2000 and is the subject of this paper. The dose from 90Sr (and 89Sr) are supported strongly by ~30,000 measurements made with a tooth-beta counter, measurements of bones collected at autopsy, and ~30,000 measurements made with a special whole body counter that detects the bremsstrahlung from 90Y.
