(3) Analysis of bottom sediments for mineral types, especially 
for components known to have high absorptive capacities, e.g. the clays. 
(4) Analysis of bottom organisms and bottom deposits for exist- 
ing radioactivity. This will be low prior to disposal, being primarily 
from natural activities and fall-out. The analysis should be conducted 
so as to distinguish between naturally occurring K40 and C14 and man- 
made isotopes, especially Sr90. 
(5) The existence of commercial and sports fishing activities 
within and adjacent to the selected area, determined by reference to U.S. 
Fish and Wildlife records and state and local authorities. 
Monitoring of a disposal area at intervals following the start of 
disposal operations will be essential to the safe and efficient use of an | 
area. Monitoring procedures should include the collection of both 
bottom living organisms and bottom sediments, and analysis of each for 
radioactivity. The frequency of sampling and the methods of analysis 
should be such that estimates of the following can be made: 
(1) the containment provided by disposal canisters; 
(2) the distribution of waste components in the biota and the 
bottom sediments; 
(3) the existence of a steady state involving disposal rate and dis- 
tribution within the disposal area. 
DISPOSAL AREAS 
Suggested disposal areas are shown in figure 7, and their exact 
location listed in Table VI. 
Inasmuch as there are a number of disposal areas presently 
available, designated as "'explosives dumping area" or "dumping ground 
(by permit only)''’, some of which have been used heretofore for the dis- 
posal of low level radioactive wastes as well as for certain toxic chem- 
ical wastes, we have included these areas in the list of suggested sites. 
We have numbered the sites 1 to 12. Alternative sites have been marked 
with the subscript a or b indicating that they might be used as secondary 
disposal areas but are more inconvenient to reach than the primary dis- 
posal area. 
Most of the dumping areas are large: 10 x 10 miles, 10 miles in 
diameter, or the like. We have indicated the centers of these areas, 
with one exception. Additional sites listed might be two miles in diam- 
eter centered on the positions given. Sites presently listed in ''A special 
report on disposal of radioactivity into Atlantic Ocean waters—past, 
present, and predicted", U.S.A.E.C. Division of Reactor Development, 
November 1957, are marked with an *.
