Reassessment of the Atomic Bomb Radiation Dosimetry for Hiroshima and Nagasaki. Dosimetry System 2002. Volume 2

Editors Robert W. Young and George D. Kerr, Hiroshima: Radiation Effects Research Foundation, 2005 - 551 p.
The publication presents the independent work of the U.S. and Japanese Working Groups on the atomic-bomb dosimetry in survivors of A-bombing of Hiroshima and Nagasaki by U.S. in August 1945. That unbiased development of the new dosimetry system will reflect well in its application in the Radiation Effects Research Foundation (RERF) epidemiology study. That study for decades provides the scientific basis for development the Recommendations of the International Commission on Radiological Protection (ICRP). The documentation included in this report serves as reference for the many deliberations concluded.
The extensive efforts to review the dosimetry of the atomic-bomb survivors and formulate the new dosimetry system DS02 have been greatly welcomed by the Radiation Effects Research Foundation. This accomplishment is a fine tribute to the importance of the epidemiological studies being conducted at RERF. No other study is so informative of the effects of radiation on human health. The gracious participation in the RERF program by the atomic-bomb survivors allows the RERF to contribute to the well being of these individuals, and the high quality of the data obtained allows the RERF results to feature so prominently in the formulation of international guidelines for radiation protection. Such a great effort to improve and substantiate the dosimetry would not otherwise have been justified.In situ measurements and calculations.
