CORROSION COMMENTARY

CANNED DRINKING WATER. THE protection given by the tin‐coated steel can against nuclear radiation has been recognised since the Bikini atom bomb tests in 1951. After the tests canned food and beer left on ships exposed to the explosions were found to be uncontaminated by the deadly gamma rays. This has led to the development of a new industry in the U.S.—the canning of drinking water. Hospitals and civil defence units are reported to be laying in stores of canned water for possible use in case water supplies become contaminated in an atomic war.
