The assumption hcre is that wherever practicable, aireraft schcduled to be in the region between Eniwetck and Pikind ,tolls will be equipped to measure and report ratiation cncountered. Lk. Data to Obtained: The basic requirement for these flishts is to establish a fille of data of sufficient accuracy to support conclusions Telating to health hazards likcly to drift ant fall out on Eniwetok and Ujeleng atoll, and to support decisions rclative to the necessity for evacuation. Since highly precise measuroments are not required, suitable naDIaC equipment and reporting codes are spacificd below accordingly, It is intended that, whore practicable, aircraft crows encountering radiatisn attempt to determine the approsximato size of the affected srca and the position of th. leading edge of the cloud, This information is basic in determining the probably fall-out sffect on Ujelang and the Eniwetck atoll Cam site. 5.
