THE URTER COKCENTRATIONS OF PLUTONIUM IN BOTH POPULATICHS ARE
WELL BELA LEVELS DETECTED .BY USUAL LOW-LEVEL COUNTING PROCEDURES
AND WELL BELOW LEVELS FOR WHICH WE HAVE EXPERLERCE IN ESTIMATING
THE AMOUNT OF PLUTONIUM iN TUL BODY,
BECAUSE CF rms
ND IN
VIEW OF ora FACTORS SUCH AS COMPLETELY DIFFERENT LIVING AND
PIN STOLGGICAL PATTERNS OF THE TWO POPULATIONS, THE POSSIRLE
SIGRIFICARCE OF THIS FINDING 15 VERY. UNCERTAIN, . IN ADDLTICN,
THE METTIOD OF SAMPLING IS SUCH mst VERY SMALL LEVELS oF
ENVIRCIGIENTAL PLUTONIUM MIGHT HAVE CONTAMINATED THE SAMPLES,
