Co @ characteristics, vegetation, humidity, rainfall, mechanical distrubance, physical and chemical history of plutonium particles in soil. How then does one consider the exposure of children throwing dry sand on a windy day at the beach? I would anticipate large fluctuations abcut the inplicit exposure levels, which, even for the limiting soil contamination guidelines and predicted air concentrations associated with these guidelines, will be approximately a maximum permissible lung burden. (Personal Communication.) Each of the questions raised here and in the related appendices must be addressed fully and carefully prior to resettlement of the people of Enewetak Atoll. 3.3 Plutonium Soil Standards Concerning the standard employed by the DEIS for maximum . permissible plutonium contamination of soils at Enewetak, Dr. Martell points out that "There are no ICRP standards for soil levels of Pu and the actinides or for lifetime exposures to internal alpha emitters." (Personal Communication.) And he provides the follcwing critique of the standards adopted by the AEC Task Group for Enewetak: The recommendation that plutonium contaminated | 239+240 soils, with levels not exceeding 40 pCi Pu/g of soil averaged over 15 cm depth, is suitable for human habitation, can be very seriously questioned. The Stete of Colorado Board of Health has adopted interim standards for Pu contamination limits in soils =l1-
