Observed and computed Dias directions are shown for comparison. tive platforms are C.16, 0.44 and 0.85. The bias fractions of the respec- Collection curves of all the YAG platforms were also completed by interpolation as in the case of the HOW curves and the three illustrated curves typify the curves of the remaining YAG platforms and m.w. systems. Only the YAG collections were subjected to bias vector analysis. For each platform the number of winds involved, their directions, their velocities and their durations were availiable from RA date. The relative amounts of fallout associated with each of these winds were derived from TIR data rather than the results of the biased IC's. Ina relative sense, a TIR curve shows the over-all time variation of activity within the platform and this variation is attributed to both decay and fallout arrival. With the exception of decay, the curve is an approximation because of non-uniform fallout depositian in the pletform and the veriaole directional response characteristics of the TIR. To eliminate the decay contribution, the TIR curve was corrected point-for-point t: a common times the resulting curve then represents the approximate relative build-up of fallout with time. Relative falleut amcunts, to which vector magnitudes are proportional, are represented by the increase of activity per time increment of approximately constant wind velocity. The TIR curve of each station and the YAG 40 decay data used to correct these curves (with extrapolations) are listed in Ref. 3. The corrected TIR curves for the three illurtratei platforms are shown in Fig. B.1 and the curve points of the remaining YAG stations are listed in Table B.l. Because of a possible transient-dose peak, the decay-corrected platform TIR curves of YAG-39-D and YAG-40-A were adjusted to agree with the curves of the TIR located on the forward deck. The wind and vector information for each platform are listed in Tabies B.2 to B.5. In the case of a wind of constant directional variation (ship turning), the amount of fallout was proportioned among a number of wind increments, each accounting for a direction sector of 30° or 40°. To simplify the final vector solution the effective (resultant) vector of each group of wind increments was separately determined and sub- stituted accordingly. by Fig. 15.
