The radiation levels in Tokyo town faucet water has decreased back again under the safety limit with regard to babies, Kyodo media agency announced on Thursday.
Nevertheless, Chiba prefecture, adjacent to the capital, seems to have detected radioactive substances in their water filtering method within amounts above what is considered safe for children, Kyodo said. On Wednesday, radiation levels in Tokyo’s regular faucet water exceeded a risk-free amount for newborns and the authorities urged residents not to provide plain faucet water to children under 12 months old. Earlier on Thursday radiation amounts over safety norms intended for children had been discovered in one more neighbouring prefecture, Saitama, but Kyodo stated two hours later on that they had fallen back again.
The worry about radiation in drinking water may come as employees try to protect against leakages of radiation coming from the earthquake-damaged nuclear energy plant 240 km (150 miles) northern of Tokyo.
