Re: Think of the Paper work! - Sewer Leak at WSU



Another problem which a research reactor encountered from the disposal of 
radwaste via sanitary sewer is that the sewage treatment plant
reconcentrated 
the diluted radioactive material in the sludge.  This sludge had been
shipped 
to the municipal landfill. When this facility closed, the sludge was shipped 
to a commercial site, where incoming shipments were surveyed.  These surveys 
detected the radioactive material in the sludge, which was traced back to
the 
reactor. 
 
Although allowed by 10CFR20, sewage disposal of long-lived radioactive 
material may not be acceptable. 
 
The opinions expressed are strictly mine. 
It's not about dose, it's about trust.
