geen repugnance, They point out that 71% of the earth's surface is They note that the sea as compared to the land is relatively nonradioactive, of igneous rocks, following: Natural radioactivity of the seas is 1/100 that As a result of weapons tests they report the two days after Operation Castle was over in the spring of 1954 there was a million-fold increase in radioactivity on the surface waters near Bikini; that after four months 1500 miles away it was three times the normal amount and that at the area of surface water contamination square miles, 13 mnnths had spread cver a million and that at a distance of 3500 miles from Bikini the "artificial" radioactivity was 1/5 the natural. They concluded that to date there has probably been no damage to life in the sea except that at the test site proper, They call attention to concentration of radioactivity by plant forms in the sea and warn repeatedly against indiscriminate dumping of radioactive wastes into the sea, They discuss the "flushing time" of the Black Sea 2500 years as compared with perhaps 100 or 200 years for the shalf-deeps of the Atlantic and Caribbean, They stress they need to know much more about the ocean depths and their movements, (The International Geophysical Year has a very large-scale study of the depths planned for 1957-58). This committee would apparently permit "controlled" sea disposal especlaily of short-lived radioactive materials, They recommend that “Industrial agencles formulate conventions for the safe disposal of atomic wastes at sea, based on existing knowledge." move. This would seem to be a very logical and necessary To date, except for small amounts of short-lived material, the U, S, has not dumped any radioactive wastes in the sea, are still storing all process wastes in tanks. -~ 13 - Enclosure ITI We LaeEe we ocean and that eventually everything gets into the oceans,
