- Corrected for.50% efficiency of the NNFD waste treatment plant LRC Air Activities released at the top of a 150 Foot Stack For che First Six Months of 1979 Activi ty Concentration **
0.02 pCi
< 5.3 x 10-20 Ci/ml Gross alpha particulate 0.41 uCi
< 9.7 x 10-I9 pCi/ml Gross beta particulate Kr-85
< 16.5 Ci
< 3.9 x 10-II pCi/ml H-3 l.4 Ci
< 3.3 x 10-12 Ci/ml
- Average for the six month period including 3,000 dilution factor for stack.
Note:
Actual concentrations of long lived particulate activities in the stack discharge are less than background activities, because a large portion of the air in the stack enters through " Absolute" filters.
Since the concentration is less than background there is no reason-able way to measure what contributions come from environmental back-ground or from laboratory processes. Therefore the number reported is a maximum and not only includes environmental background but in all probability is environmental background.
