FROM D, C. SEWELL, SCIENTIFIC OPERATIONS DIRECTION, CIT CLN BY 57-56
WE PEEL THAT INTERNATIONAL OBSERVATION OF FALLOUT REDUCTION PROM
CLEAN BOMBS IMPLIES:
TECHNICAL MEASUREMENT OF REASONABLE
PRECISION, THE CREDIBILITY OF SUCH MEASUREMENTS TO INTERNATIONAL
OBSERVERS, AND PROBABLY A FEELING OF SATISFACTION ON THE PART OF
THE OBSERVERS OVER AND ABOVE THE NECESSARY CREDIBILITY REGARDING
THE TECHNICAL MEASUREMENTS. .
IN MAKING SUCH A DEMONSTRATION IT WOULD BE VERY DESIRABLE TO
HAVE A PAIR, CONSISTING OF TWO PROOF TESTED DEVICES OF NEARLY
THE SAME TOTAL YIELD BUT QUITE DIFFERENT FISSION YIELD LEVELS
TO DETONATE, MEASURE, AND COMPARE,
OBVIOUSLY A LOW TOTAL YIELD
FOR EACH IS DESIRABLE.
AT THIS TIME WE DO NOT BELIEVE THERE IS TIME, BY HARDTACK, TO
DO A GOOD ENOUGH TECHNICAL JOB TO BE USEFULLY CONVINCING.
WE
BELIEVE THAT SUCH A JOB COULD BE DONE, GIVEN SUFFICIENT TIME.
THIS REQUIRES TWO STEPS.
ONE, MORE TECHNICAL INVESTIGATION
