Traces  of radiation spilled from Japan’s hobbled nuclear plant were detected  December 6 in baby formula manufactured by Meiji Co, a major food and  candy maker. The formula had been manufactured in March. The company has  recalled the formula although the Japanese authorities insist there is  no risk to babies' health. This despite the scientifically-held position  that there is "no safe dose" of radiation and studies that show  prolonged exposure to low levels of radiation can be harmful.
