(i.e., averaged over the top It is noteworthy that the AEC has not established that this standard is unduly consecvative and it is not apparent that the AEC has requested the ICRP or NCPP to make specific recommendations with respect to standards for Pu in Soils applicable to°chronic exposure to the general public, including children. I note that the DEIS recommends no remedial ‘action for soils containing « 40 pCi or « 88 dom Pu/g, averaged over the top 15 cm depth. This is much more than 44 times the Colorado interim standard (2 dpm per g in the top 1 cm) because for most Enewetak soils the top cm contains substantially higher levels of Pu per gram than the 15 cm depth average. Thus, for example, at location 101 on Pearl, the top 1 cm depth shows 400 pCi 239u/s, whereas the average over 15 cm depth is about 60. Thus the recommended standard for Enewetak is about 100 to several hundred times that adopted in Colorado. There are recent research developments which are expected to lead to reductions in acceptable Organ burdens of Pu in man by a factor of 100 to 1000 or more. In my opinion it is likely that a 10
