The scope of radiation-contaminated tap water expanded Thursday, with radioactive iodine detected in tap water in Chiba, Saitama and Ibaraki prefectures, while the Tokyo Metropolitan Government, which said the day before its drinking water was contaminated, scurried to distribute 240,000 bottles of water to households with babies.
Chiba authorities urged parents not to give tap water to infants less than 1 year old. Saitama refrained, at least initially, from taking similar measures after the level of iodine fell below the regulated limit later Thursday.
Hitachi, Ibaraki Prefecture, started Thursday distributing water to make formula for infants.
