that are to be food for man. 



That no shore line hazard will be created by the stated quantities 

 of activity in the suggested locations was concluded after estimating the 

 maximum concentration of activity that could result at various dis- 

 tances from the disposal site as a result of mixing and dilution of the 

 waste by turbulent diffusion processes and transport by ocean currents. 



The conclusion that fish will not become contaminated to hazard- 

 ous levels is based upon an estimate of the quantity of activity that 

 would be received by man, assuming that fish is his sole source of 

 protein for about thirty years, and that the fish remain for at least one 

 month within one kiloineter (about 5/8 mile) of the center of the dis- 

 posal area, and always on the downstream side. Even under these 

 unlikely conditions, the total quantity of radioactivity that would be 

 ingested by man is below hazardous levels, for present levels of pro- 

 duction of low level wastes. 



The calculations of the extent of mixing and dilution due to 

 turbulent diffusion provide conservative estimates of the concentration 

 that would be observed in the natural system. That is, the calculated 

 concentrations are higher than the actual ones. 



Completely omitted from these considerations is the process of 

 sorption of the wastes on naturally occurring sediment components in 

 suspension and on the ocean floor. It was found impossible to make a
