The objectives of this project were to measure neutron flux and dose as a function of distance for two nuclear detonations and to make neutron flux measurements as required by other Department of Defense projects. The Hurst fission foil method was used to measure flux. Au197, Pu239, Np237, U238, S32, and Zr90 were employed as detecting materials. Steel buoys were used to support the detecting materials in the Enewetok lagoon. Twenty five stations were placed at distances varying from 917 yards to 4,100 yards for two large yield devices, Neutron dose was calculated from the measured fluxes by using the single-collision theory of dose contribution per neutron.
