The Tokyo metropolitan government warned Wednesday that infants should not drink tap water as radioactive iodine exceeding the limit for them were detected in water at a purification plant.

According to the metropolitan government, 210 becquerels of radioactive iodine were detected per 1 kilogram of water against the limit of 100 becquerels. Officials said the limit for consumption of iodine 131 for infants is 100 becquerels per liter. They recommended that babies not be given tap water, although they said the water is not an immediate health risk for adults.
