This effort to declassify this report has been accomplished specifically to support the Department of Defense Nuclear Test ;Otrsonntl Review CNTPR) Program. The objective is to facilitate studier of the low levels of radiation received by sane individuals during the atmospheric nuclear test program by amking as much information as possible available to all interested parties. The material vhich has been deleted is all currently classified as Restricted Data or Formerly Restricted Data under the provision of the Atomic Energy Act of 1954, (as amended) or is National Security Information. This report has beta reproduced directly from, available copies of the original material. The locations from vhich material has been deleted is generally obvious by the spacings and “holes” in the text. Thus the context of the material deleted identified to assist the reader in the determination of whether the deleted information is germane to his study. It is the belief of the individuals who have participated in preparing this report by deleting the classified material and of the Defense Nuclear Agency that the report accurately portrays the contents of the original and that the deleted material is of little or no signiiicancc to studies into the amounts or Lypes of radiation received by any individuals during the atmospheric nuclear test program. BI , Distribution/ Availability codes r -- -. ,. _. *. - ACKNOWLEDGMENTS The basic planning for the activities of Task Group 7.1 in Operation Redwing was done under the direction of William E. Og.2, Deputy Command- er for Sctentific Matters, Joint Task Force Seven, who until January of 1956 was Task Group Commander, and it is to him that credit should be given for the concept and major policy determinations. This report is a description of the way in which his plans were carried out. Like the Operation itself, this report is the work of many people. R was assembled by the Task Group staff under the direction of Duncan Curry, Jr., Deputy for Administration, Task Group 7.1, from data provided by Pro- grams, Projects, Task Units, and Staff Sections.
