LATER SUmVEIS
During the pestwod d te li Mareh, uore extended surveys of each of
the islands wore made Ly a monitoring teun equipped with fiva AN/POR-39
instruments (heferonan |), Menty-four hours previous to the departure
of the Survey party, three of the instrunents were calibrated on an
BOWcurie Co source and cross checked at 0.329 rfhr, whero they were
found to be in close agreement, Using these instructs, measurenents
were made in the inhabited arcas of all four islands at waist heirht
(approxtnately 3 feet above ground), Table 2,4 ts a swanary of these
data, Since these later readings were made under better controlled
conditions than thu emer pency surveys at the tines of evacuation eiven
iu Table 2.2, the data ef Table 2.) were taken tu be the Lost measure-
ment at a piven tine of the vanma duse rates in alr ani were used in
the calculetilon of the total axterral vcaina dose.
No infomation existed on tha Geant ty of beta contamination on
the skin of any of the exposed individuals,
Further, no experimental
data allowed any reldatle calculation of thne be ta dose rate to an
individual fram fission products on tha prevund, Thuis the only basis
for any estimate of axternal beta dosace waa data from other field
tests and fallout measurenents,
This question is discussed further in
Chapter 6, and a rough estinats for possible beta dose frua tho ground
