5.2.2 Disposal of Nonradioactive Materials
5.2.2.1 Salvage. The disposal of nonradioactive debris does not have
the many problems connected with the disposal of radioactive materials.
Salvageable material will be collected and stockpiled in designated areas
as {hs cleanup Bigsres ses. This material will be used by the Enewetak
people “and it would be carefully monitored to make certain that no radioactive substances are included.
5.2.2.2
Combustibles.
Combustible nonradioactive debris would be
hauled to a burn pit on each island where it would be burned to ashes.
The ashes would be gathered and stockpiled for future use as a soil
conditioner.
The pit would then be backfilled with native material and
the area regraded to its natural contours. Some of the nonradioactive
vegetation removed during cleanup also would be shredded to a very small
size to be used as additional organic matter in the soil.
5.2.2.3 Fish Reefs. Nonradioactive debris that remained after salvage
material and combustibles had been segregated would be removed and
dumped into the lagoon at selected spots to form artificial reefs to
enhance the breeding of fish and other marine life.
5.3 RADIOLOGICAL HAZARDS
.

Detrimental effects have been observed incidental tothe use of
radiation since soon after it was first discovered. These effects/Fange
from a temporary reddening of the skin to an increased incidence of
cancer. A recent review (BEIR, 1972) on the biological effects of ionizing
radiation serves as the basis of risk analysis in the current document.
Other studies reporting similar data are UNSCEAR, 1972 and ICRP-14,
1969.
