The graph on the left shows the cumulative airborne effluent emissions of plutonium from building stacks through August 2000.
Emissions are consistent with previously measured plutonium concentrations.
The total 1999 plutonium emissions were 0.096 uCi. Americium and uranium emissions for 2000 are also within the ranges seen in 1998 and 1999. The monthly tritium airborne effluent emissions for 2000 are below the mean monthly emissions in 1998 and 1999. The graph on the right illustrates the monthly estimated maximum potential dose rates at the perimeter sampler showing highest radionuclide concentrations, including contributions from naturally occurring uranium isotopes. The highest dose rates for 2000 were seen at location S-132.
