Description/Abstract:
THE MARINE SURVEY UNIT HAD AS ITS MAJOR OBJECTIVES ( 1 ) THE MEASUREME NT OF THE RESIDUAL RADIATION OF ENIWETOK ATOLL AS FOUND IN THE LIVING ORGANISMS AS A RESULT OF PREVIOUS WEAPONS TESTS IN THIS AREA, AND ( 2 ) A RESURVEY OF THE AREA, FOLLOWING THE MIKE SHOT, TO DETERMINE THE C HANGE IN AMOUNTS, KINDS AND DISTRIBUTION OF RADIOACTIVE MATERIALS. TH E FIELD DATA WERE COLLECTED BY A PARTY OF SEVEN SPECIALISTS WHO SPENT THE TIME FROM OCTOBER 20 TO NOVEMBER 11, 1952, COLLECTING PLANKTON, A LGAE, RATS, BIRDS, FISHES, PLANTS AND INVERTEBRATE ORGANISMS. THE MAT ERIAL COLLECTED WAS FROZEN FOR STORAGE AND SHIPMENT BACK TO THE APPLIE D FISHERIES LABORATORY WHERE IT WAS IDENTIFIED, DISSECTED, WEIGHED, AS HED, AND THE AMOUNT OF RADIATION MEASURED AS DISINTEGRATIONS PER MINUT E PER GRAM OF WET SAMPLE. THE PRE-TEST SURVEY SHOWED MEASURABLE AMOUN TS OF RESIDUAL RADIATION ON AND IN THE LIVING ORGANISMS COLLECTED FROM THE STATIONS ALONG THE EASTERN AND NORTHERN PORTION OF THE ATOLL. F OLLOWING THE MIKE SHOT THE RADIATION LEVEL INCREASED MANYFOLD, ESPECIA LLY ALONG THE NORTHERN AND WESTERN PORTIONS OF THE ATOLL. IT WAS FOUN D THAT SOME OF THE ORGANISMS COLLECTED AND STUDIED HAD BEEN EXPOSED TO SUFFICIENT EXTERNAL AND/OR INTERNAL RADIATION TO EVENTUALLY DAMAGE O R DESTROY THEM. SUBSEQUENT STUDIES SHOULD DETERMINE THE BIOLOGICAL HA LF LIFE OF THE MATERIALS CONTAMINATING THE AREA, THEIR SHIFT IN POSITI ON WITH THE CURRENTS, AND THE RESULTS OF THE CONTAMINATION FROM RADIOA CTIVE MATERIALS UPON THE LIVING FORMS OF THE ATOLL.
