Radioactive iodine has been detected in Tokyo tap water in levels above the safe limit for infants.
The Tokyo Metropolitan government says 210 becquerels of iodine-131 were detected on Tuesday in one liter of water at one of its purification plants in northern Tokyo.
A sampling on Wednesday also showed roughly 190 becquerels per liter.
These levels are below the 300-becquerel per liter safe limit for adults, but far above the 100-becquerel limit for infants.
Tokyo says infants in the central 23 wards, plus 5 adjacent cities, should refrain from drinking tap water.
It is also urging beverage makers in these areas not to use tap water in infants' drinks.
Tokyo says the safety level assumes long-term consumption, and that there is no risk to health if tap water is consumed over a short period.
