Final Report of Manhattan Investigation
HOME>Final Report of Manhattan Investigation


Final report of findings of the Manhattan district atomic bombs investigating groups at Hiroshima and Nagasaki(19 April 1946)
The general purpose of the mission was twofold. The more comprehensive aspect was to observe the total effects of the atomic bombs on the cities and the people exposed. The specific objective was to investigate any unique effects due to radiation.
The medical study is presented herewith. The study concerning radioactivity (Tybout) is presented in Section B of this report. The investigations of physical damage to Hiroshima (Varley) and to Nagasaki (Youngs) constitute Section C.
