The average exponent for the period H # 8 hours to H # 50 hours
is -0.97.
Typical beta decay ani gamma dose rate decay curves were prepared.
These curves cover the period H # 60 to H # 50 hours.
Measurements
will continue to be made until H # 1000 hours,
Analysis of intermittent fallout collector data, particle size
data, and radicchemical data is in progrees.
A significant portion
of this infermation should be available in time for inclusion in the
preliminary report at the end of the operation,
