The island was prepared for agricultural redevelopment by cutting parellel
strips through the vegetation along.the length of the island.
The vegetative
“cover was knocked down and left in place to provide additional organic matter
for the soil.
The strips were surveyed and background gamma radiation levels
recorded at 250-foot intervals along their length.
Figure 1 illustrates the
background variation by depicting the range and average of gamma radiation
measurements taken at three feet above the ground for areas consisting of
°
approximately four strips.

ranged from 20-120 uR/hr inland.
