DISPOSAL OF CONTAMTIATED MATIRIAL
For disposal of contaminated material, there appears to be several
categories, each requiring separate consideration:
1. Contaminated scrap, non=«plutoniun.
2. Contaminated soil, non-plutoniun.
3. Contaminated scrap, plutonium,
4. Contaminated soil, plutonium.
5. Pieces of plutonium metal,
Some of the above are below the ground ‘surface such as in burial sites.
Some {s near the surface such as the pieces of plutonium metal on YVONNE.
With regard to disposal, the Task Group considers it appropriate to cite
the cbjectives for disposal, to list pessitjle approaches for disposal, and
to suggest pcessible interim measures where’ avopropriate.
Table 12 and the discussion in NV-140, Vol. I, contains information or
known or suspected burial sites for radioactive debris.
The Uolmes and
Narver "Engineering Study For A Cleanup Plan, Enewetak Atoll-Marshall
Islands," ln.-1348.1, contains information on the location and quantity of
other above ground contaminated scrap.
Considering the relative short radiolosical halftimes for the fission
products and induced radicactivity found on such scrap and debris, the Tas
Group suggests that the objective for dispesal is to make this debris,
particularly scrap metal, unavailable to the people when they return.
Possible approaches for disposal are:
1. Disposal in water filled and underwater craters.
2. Shallow land burial wherein the radiation level of the scrap
is not sienificantly grcater than the radiation level on land.
