Pieces of metal scrap with varying amounts of °°Co contamina-~

tion were found scattered about the western part of Eneman.
These were mostly steel cables and pieces of steel reinforcing
rods in concrete fragments.

Enidrik

Enidrik is the largest island of the southern group and
is fourth largest of the atoll.
It is less than one mile
west of Eneman.
The vegetation is quite thick, particularly
in the island interior.
There are stands of cordia and
pisonia trees and several pandanas trees with the usual
ground cover of scaevola, messerschmidia, and guettarda.
Several survey transects were made from lagoon to ocean side

on the eastern part of the island.
Survey of the larger
western part was less systematic due to the density of
vegetation.
Readings with the G-M counter on the eastern part of
the

island generally ranged

from 3 to 10 ur/hr.

In one area

near the eastern end, a reading of 30 pr/hr was obtained.
Some metal scrap in this region exhibited significant
contamination.
The western part of the island showed variations in the
radiation levels similar to Bikini - low leveis near the
ocean and lagoon shore with higher levels inland, indicative
of greater retention of radioactive products by the organic
soil.
Measurements with the scintillation counter ranged
from 3 to 19 ur/hr on a transect near the center of Enidrik.

The range was 9 to 235 ur/hr on a transect farther to the

west.

The low level was near the ocean high tide line.

Mid-island on this transect the levels were around 30 to 90
