Cleanup of soil containing Pu can be handled ona case-by-case basis using the following: ae <40 pCi/gm of soil - corrective action not required. b.. 40 to 400 pCi/gm of soil - corrective action determined ‘ona case-by-case basis considering all radiological conditions. c. > 400 pCi/gm of soil - corrective action required. DOSE ASSESSMENT AND CORRECTIVE ACTION ALTERNATIVES For comparison with population dose guidelines, evaluations were made for the following conditions: » Dose without cleanup. - Dose reductions obtained by diet modification. » Dose reductions achieved by removal of contaminated soil. In addition, estimates were made for representative living patterns plus corrective actions: . Plow the village island, and gravel the village area for radiation shielding. » Import pandanus and breadfruit from the southern islands (ALVIN-KEITH) for inhabitants of the northern islands to control ingestion of radionuclides. » Import pandanus, breadfruit, coconut and tacca from the ° Import pandarus, breadfruit, coconut, tacca, and domestic meat from the southern islands. , southern islands. . DISPOSAL OF CONTAMINATED MATERIAL ee a Contaminated material is composed of soil, debris and scrap. At some places there is Pu including pieces of Pu metal. Contamination is distributed on and below the surface; some is in rad waste burial sites. Fission products and induced radioactivity found on such scrap and debris, particularly-scrap metal, should be made unavailable to the returning people.
