Preliminary Analysis of the Application of Fallout Monitoring Data to Fallout Prediction During and after a Nuclear Attack

摘要

The applicability of fallout monitoring information to the improvement of prediction of the distribution of fallout during or after a nuclear attack is discussed. An analytic technique is developed for predicting fallout radioactivity surface density (or exposure rate if converted) at locations downwind from a monitoring station at which a measurement of radioactivity surface density or exposure rate is taken after fallout cessation. Also developed is a method for predicting fallout arrival, deposition-duration, and cessation times for points in a fallout field based on measurements of these parameters at a single monitoring station.
