Status of Los Alamos efforts related to Hiroshima and Nagasaki dose estimates
The Los Alamos efforts related to resolution of the Hiroshima, Nagasaki doses are described as follows: (1) Using recently located replicas of the Hiroshima bomb, measurements will be made which will define the upper limit of the Hiroshima yield. (2) Two-dimensional calculations of the neutron and gamma-ray outputs of the Hiroshima and Nagasaki weapons are in progress. Neutron and gamma-ray leakage spectra measurements will be made. Similar measurements on the Mark 9 weapon and on the Ichiban assembly are proposed. These measurements will provide a check for present day cross sections and calculations. (3) Calculations of several air transport experiments are in progress. A comparison of calculated results with experimental results is given. (4) The neutron and gamma-ray output spectra of several devices tested in the atmosphere at the Nevada Test Site are being calculated. The results of these calculations will allow models of the debris cloud contribution to the total dose to be tested. (ERB)
