Abstract:

Particle rate of fall, available actual wind data, and total fallout radioactivity as a function of particle size have been critically reviewed as a basis for determining wind-weighting factors (WWF). Based on recently published analyses of fallout particle data, the recalculated typical (or nominal) diameter of radioactive local-fallout particles is 137 microns. A set of WWF for calculating mean effective wind vectors has been determined for use with actual wind data in predicting the location and military significance of radioactive fallout deposition. The WWF are used with fallout models such as the Weapons Systems Evaluation Group (WSEG) model.
