A simple experiment was conducted on Bikini Island to assess the potential
exposure rate effect and reduction by concrete living quarters made from

aggregate obtained from the PETER-OBOE complex.
A concrete house was simulated by constructing a large square container
with hollow walls six inches thick.
The walls and the bottom six inches
were eventually filled with aggregate (obtained from the PETER-OBOE complex)
after the container was placed in an area of relatively high exposure rate
(125 uR/hr).
A compartment was located in the center of the structure in
which a Ludlum scintillation survey meter was placed to measure exposure
rates without aggregate, with six inches of aggregate on bottom, and with
‘
walls of aggregate.
Results of this experiment are as follows:
Background
125 uR/hr
Six inch aggregate bottom
75 uR/hr
Six inch aggregate bottom
45 uR/hr
plus six inch walls
Similar results were seen when exposure rates wore measured inside

of a drained concrete cistern in the camp area, and which was constructed with
