Lawrence T. Dauer, Memorial Sloan Kettering Cancer Center, New York, NY The study of low dose and low-dose rate exposure is of immeasurable value in understanding the possible range of health effects from prolonged exposures to radiation. The Million Person Study of Low-Level and Low-Dose-Rate Health Effects (MPS) is designed to address the major unanswered question in radiation risk understanding: What is the level of health effects when exposure is gradual over time and not delivered briefly. Over a million healthy American workers and veterans are being studied to evaluate cancer and non-cancer mortality following low-level low-LET and high-LET exposure, rare cancers, intakes of radioactive elements, and differences in risks between women and men. Overall, about 34 individual cohorts comprise the MPS. This presentation will provide an overview of the scientific approach for MPS, using specific cohorts and investigations as examples. Discussion will include the purpose for studying one million U.S. radiation workers and veterans, the general methodology, status, selected results, and planned expansion and vision.
