Maybe you have heard about the increased levels of radioactive iodine in Tokyo tap water. Yes, the levels have increased but are still far below the threshold. In Sweden the threshold for radioactive iodine in liquids is 500 Bq/kg. In Tokyo tap water 2.9 Bq/kg was found, which is well below the Swedish threshold and even well below the Japanese threshold of 200 Bq/kg.

It was only one village with extremely high levels (more than 3 times the threshold) in the tap water where they have recommended people to not drink the water. This village, I forgot the name now, was basically within spitting distance from Fukushima #1 plant, or at least partly within the evacuation zone.
