CORROSION STUDIES OF IRRADIATED CANNED FOODS. Report No. 6 (Final), December 17, 1954-December 31, 1960
Gamma radiation of 3.25 Mrad had no adverse effects on the metal, enamel coating, or end lining compound of tinplate cans. The lomgest sheif-life for irradiated green beans in tinplate cans was l6 mo. It was concluded that the problem of early failure of enamel on the ends of these cans could be avoided by the use of unenameled hot dip plate for the ends, as well as bodies of the cans. A study was made of causes of gas production in food products during irradiation. Ground beef packed in polyethylene tubes with experimental epoxy resin coatings and exposed to 6 Mrad gamma radiation showed surface darkening after one month. Plastic bags of chili con carne and cherries were exposed to 6 Mrad gamma radiation. Only polyester Scotch-Pak containers of chili did not leak after 3 mo storage at 98 deg F. Cherries were held 3 mo at 98 deg F without leaks by vinyl, nylon, polyvinyl chloride on Mylar, and metallized Mylar bags. Saran and Genitron bags leaked with both products. (C.H.)
