The report summarizes the fallout pattern scaling relationships that were developed in the period 1962 to 1964 the report includes the values of the scaling equation coefficients that were derived from selected fallout pattern data. The meaning of the scalar wind speed multiplier that is used in the scaling equations is discussed relative to computer applications of the scaling system and approximate wind speed adjustment factors for use with wind speed averages that may be assumed in such applications are provided. Basic equations for relating surface density of radio nuclides and air ionization rates are given. Scaling equations and data are also presented for use in estimating, for any location in the fallout region, the time of fallout arrival, the time of fallout cessation, the variation of the exposure rate i.e., air ionization rate in roentgens per hour with time during fallout arrival, and the total potential exposure from the time of fallout arrival to selected later times.
