Project 2.65 = Analysis of Fallout ani of Base Surge ~- M, Morgenthau
OBIZCIES
The goenerel ohiectives of project 2.65 participation in REDWING
were to:
Obtain fallout samples on land ani ts perform radiophysical
and radiochemical measurements on the samples;
prepare dose rate con-
tours of she atoll erea from information gathered by this project,
other projects, and Rad Safe; ani evaluate the role of the base surce
in transport of radioactive material.
DESCRIPTION AND PXPEE IMENTAL FROCEDURYS
-y
Instrumentation was similar to that used for ad
(CHFROKTFF),
»
On D-day, DA 1, ani dD 2 an serial survey of residual radiation
was maje over the atol!) ty helicopter.
The measurem-nts vere taken by
meats “f a probe on a long cable suspeniel below the hovering helicopter,
Base sur,« tetectors were installei on three 3ikini sta‘icns to
recorit the arrival of the base surce,
These iletectors collectal infor
mation to be used in conjunction with Project 2.2 gamma versus time
data and IFC data to evaluate the role of base surge as a carrier of
railoactivity,
Radlochetical analysis will be performed on the IFC
semp)os in an attempt to establish whetber the base surge is @ conta
inating event iniepenient of the fallout.
