of transportation to be used, and a brief summary of the specific mission. A code designation was assigned each mission to facilitate communication by radio with RadOps on the BAIROKO. The priority of missions was also designated as ROUTINE or URGENT. A rough draft of this schedule was given a thorough study, and shortly before X-RAY day 4t was mimeographed in final form and distributed to all personnel concerned, However, by X-plus-] day it was found necessary to schedule a number of additional missions which had not been anticipated. Finally, the program became so accelerated as a result of encountering lower radiation intensities than had been expected, that the original operations schedule became no longer applicable. Therefore it became necessary in the midst of X-RAY operations to prepare a new schedule of missions on a day to day basis. Commencing with X~plus-2, a schedule was published each night for the following day. This new abbreviated schedule gave the RadSafe party number, a brief descrip- tion of the mission, names of the monitors, type and number of instruments involved, number of film badges to be provided, the time of issue and time of departure. The two latter items expedited the work of the supply section, enabling them to prepare the proper number of various types of equipment in advance for issue when scheduled. Monitor assignments were regulated in accordance with previous exposure as recorded by the Medical Records Unit. 64 Section IX
