Values corrected for decay.
No correlation was found between body
weight of the people from Rongelap and the
total activity per 24 hours excreted in their
urine.
Gross beta activity measurements were also
made on the samples sent to NYOO, AEC.*
Their results essentially corroborate the find-

ings by the USNRDL,particularly the ratio
of the activities among the three groups studied.
The absolute values of the activity determined
by NYOO-AEC, however, were lower than
the USNRDLvalues by a constant factor.
2. Radiochemical Analysis of the Urine:
Estimate of Body Burden. Radiochemical
analysis of the Rongelap urine samples indicated that the alkaline earth and rare earth
groups together contributed 75 percent of the
