me Cleanup of soil containing Pu can be handied ona case-by-case basis using the following: a. <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, cstimates 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 northernislands to control ingestion of radionuclides. - Import pandanus, breadfruit, coconut and tacca from the southern islands. . Import pancanus, breadfruit, coconut, tacca, and domestic meat from the southern islands. DISPOSAL OF CONTAMINATED MATERIAL le Contaminated material is composed of soil, debris and serap. At some places there is Pu including pieces of Pu metal Contamination is distributed on and below the surface; someis in rad waste burial sites. Fission preducts and induced radioactivity found on such scrap and debris, particularly scrap metal, should be made unavailable to the returning people. wae "1 @ * ee + . + aos Tee meres 9. - 1 . “. * ~* . bho.
