Nuclear Radiation at Hiroshima and Nagasaki

Abstract

culties exist in that the strengths of the bombs exploded over Japan are not too well known, and the interpretation of the test measurements is not too clear. The best that can be expected is a rough upper limit for the dosage that might have been received by a person at some given distance from the explosion. What was actually received by that person depends exactly on the details of his position with respect to shielding objects in his vicinity. If necessary, this latter uncertainty might be removed in some cases by reconstructing the scene and then making detailed calculations or by making model experiments to determine the influence of the geometry on the dose. The present report will be confined essentially to an attempt to determine the idealized dosage that would obtain without intervening shielding. The most important conclusion from this study is that a significant difference in
