C2JECTIVES The general objectives of project 2.65 participation in REDWING were te: (1) obtain fallout semples on Jand and to perform radiophysical and radic~ chemical messurements on the samples; (2) prepare dose rate contours of the atoll erea from information gethered by this project, other projects, and RadSafe; and (3) evaluate the role of the bese surge in transport of radioactive vaterial. = Project 2.65 had only limited perticipation in TACHOSSE, The rain purpose for this participation was to obtain dose rate comtours ncar the crater.
