in the outflow should be guided by information that was 

 not available to us. It is quite possible that the two 

 Long Island Sound samples (#3 and #4) both show some ^Spe 

 from Millstone and that No. 3 shows also some 137cs, but 

 the signals are yery small, so that a large number of com- 

 parison samples (or large enough volume samples to give 

 good counting statistics for 134cs or 238Pu) would be 

 needed to support this sort of conclusion. It would be 

 more economical to be able to undertake detailed programs 

 of sampling water at short intervals after known releases, 

 preferably those expected to represent substantial pulses 

 of the nuclides to be measured.
