an underwater gamma radiation detector to measure radioactivity 



directly on the ocean bottom. In addition, we attempted to observe 

 waste containers with underwater television, but this had limited 

 success. The scientific crew on this survey included members of EPA's 

 Office of Radiation Programs, EPA's Water Office, the NOAA Office of 

 Oceanography, the NOAA National Marine Fisheries Service, the 

 Massachusetts Department of Public Health, the Massachusetts Division 

 of Water Pollution Control, the staff of the U.S. House of 

 Representatives Subcommittee on Coast Guard and Navigation, the 

 Battelle New England Marine Laboratories, and Science Applications, 

 Inc. of Newport, Rhode Island. 



The total samples collected in this survey included 116 sediments, 

 benthic and demersal biota from 30 trawls, 14 mid-water collections for 

 nektonic and planktonic biota, 5 water samples, 12 measurements of 

 radioactivity on the ocean bottom, 14 nautical miles of underwater 

 television coverage on videotape, and 27 nautical miles of side scan 

 sonar survey. Tne biota included 18 species of commercial seafoods and 

 9 noncommercial species. During the survey about 100 samples were 

 selected for preliminary radiation measurements onboard the ship. All 

 of tnese samples showed only normal background levels of radioactivity. 

 All samples collected have subsequently been analyzed in greater detail 

 Dy EPA's laooratory in Alabama. Preliminary data from this survey was 

 presented in a paper at the International Conference on Radiactive
