Influences of Packaging on Rate of Dispersion 

 of Radioactivity Disposed in the Sea 



Arnold Joseph 



Release Rate of Radioactivity from Packages 



The objective is to state as quantitatively as possible how 

 much and over what period of time radioactivity within a sea dis- 

 posal package can be expected to be released into a sea water 

 environment. 



Packages of radioactive wastes disposed in the sea are 

 usually made up of 18 gauge 55 gallon drums, concrete and the waste 

 materials. The wastes may be either intermixed with the concrete 

 or surrounded by the concrete in the 55 gallon drum. The drum 

 itself is likely to be second hand and perhaps reconditioned( repainted). 

 Corrosion of Steel by Sea Water

 salinity and marine organism growth from place to place, 

 there are surprisingly small differences in the corrosion 

 of common metals and alloys when they are exposed to corrosion 

 by sea water at different points throughout the world. . . 

 illustrative data for steel and iron. . . show a surprising
