ATOMIC ENERGY USED TO PASTEURIZE FISH - 1960S LS of the U.S. Dept. of the Interior\'s laboratory and CU of the building sign where a refrigerated truck from P.J. Markos Seafood Co. pulls up. Workers unload the fish into a special laboratory where it will be pasteurized in a seafood irradiator chamber that uses Cobalt 60 (radio isotope of Cobalt) stored under water to shield people from gamma radiation.

FRESH FISH PASTEURIZED WITH RADIATION - 1960S On a closed circuit TV screen scientists watch what happens when fish are exposed to cobalt 60 in an irradiation chamber for pasteurization. A tin box of fish moves along a conveyor belt passing under and over gamma rays that kill bacteria then up to a waiting worker who exchanges the irradiated fish for the next batch.

RESEARCH ON BEST METHODS TO IRRADIATE FISH - 1960S Researchers use different methods to find the most practical methods of radiation pasteurization finding that the fresher the fish is when irradiated the better the results. Cut to the Delaware, a research fishing boat that contains its own radiation processing plant so the fish it catches are irradiated immediately.

TASTE TEST BETWEEN FRESH & IRRADIATED FISH - 1960S A taste test is conducted using fish that was irradiated three weeks ago and fresh fish. The fish are prepared, cooked and arranged attractively for a group of men and women who take the food to white booths where they eat the fish to see if they can tell the difference.

TASTE TEST BETWEEN FRESH & IRRADIATED FISH - 1960S - 1 A variety of seafoods are prepared and attractively arranged as part of a taste test between fresh and irradiated foods. Men and women smell and taste the food to see if they can detect differences in flavor though none were found.

TASTE TEST BETWEEN FRESH & IRRADIATED FISH - 1960S - 2 A fishing boat brings in fresh fish then fade to a taste test where men and women must eat fish that are freshly caught and irradiated fish that have been stored then prepared. The testers grade the seafood they consume and find that many of the irradiated foods retain their freshness three to four times as long as the untouched foods.
