Chieerete =1 5 The average exponent for the perioi H # 8 hours to H ¢ 50 hours ie -0.97. Typical beta decay an} gamma jose rate decay curves were prepared. These curves cower the period H # 60 to H ¢ 50 hours. Measurements will continue to be made until H 4 1000 hours. Analysis of intermittent fallout collector data, particle sise 4ata, and radicchemical data is in progress. A significant portion of this information should be available in time for inclusion in the preliminary report at. the end of the operation. 3EST AVAILABLE COPY, - 5 - 41Gp
