In Japan, authorities in Tokyo said, the radiation levels in tap water have dropped and it is safe once again for the infants. Earlier, the government had warned that the water was unsafe for infants to drink. Other areas outside Tokyo have also detected levels of radiation which could be dangerous to infants including neighbouring Chiba and Saitama. Government's Chief Cabinet Secretary today reassured the public that any radiation levels found so far would have no effect on anyone aged over one year. He urged an increase in production of bottled water and said the work was continuing to bring the Fukushima plant under control. At the Fukushima plant, emergency crews resumed work today after officials reported a halt to the black smoke rising from the number 3 reactor that forced them to evacuate the plant yesterday. Radiation from the plant has spread as far as Tokyo, 250 kilometers to the south, and infected milk and vegetables in wide areas surrounding the plant. Australia, Canada and Singapore all joined the United States today in imposing new restrictions on Japanese food exports. Japan's National police said today that 9,700 people have been confirmed dead and 16,500 are reported missing in the disaster. About 3 lakh people are living in temporary shelters.
