Fission and Activation Cases, Iodines, and Particulates:
Airborne effluent gaseous activity is continuously monitored and recorded; additionally, grab samples are taken and analyzed monthly to determine specific radionuclide act;'ity concentrations. Stack and building vent effluent flow rates are calculated once a shift tased on the configuration of operating exhaust fans. The flow rate data is consolidated weekly to determine the volume of airborne i
effluents released from the plant.
Charcoal and particulate samples are taken and analyzed at least weekly to determine specific activity concentrations. The total activity released from the plant is then calculated by taking weekly activity concentration values and multiplying them by the weekly airborne effluent volume.
s Allowance is made for a plus or minus one sigma counting error associated with y isotopic analyses.

Measurements and Approximations of Total Radioactivity (Continued) d.
Liquid Effluents Gross beta, gamma and total y isotopic activity concentrations are determined on each batch of liquid effluent prior to release. The a
total curie content of a released batch is determined by multiplying the highest of the above three activity concentrations by the total volume discharged. The total activity released during a month is then determined by summing the activity content of each batch dis-charged during the month.
Allowance is made for plus or minus one sigma counting error associated with the total y isotopic analyses.
