Radiation Monitoring 19 March 2011, 14:00 UTC
Radiation levels in major Japanese cities have not changed significantly since yesterday. The IAEA radiation monitoring team took measurements at seven different locations in Tokyo and in the Kanagawa and Chiba Prefectures. Dose rates were well below those which are dangerous to human health. The monitoring team are now on their way to Aizu Wakamatsu City, which is 97 km west of the Fukushima nuclear power plant. They have just provided initial measurements from three additional locations.
Measurements made by Japan in a number of locations have shown the presence of radionuclides – ie isotopes such as Iodine-131 and Caesium-137 – on the ground. This has implications for food and agriculture in affected areas. The IAEA and the UN Food and Agriculture Organization (FAO) are consulting with the Japanese authorities on measures being taken in these areas related to food and agriculture.
The Japanese Ministry of Health, Labour and Welfare has announced that radiation levels that exceeded legal limits had been detected in milk produced in the Fukushima area and in certain vegetables in Ibaraki. They have requested the Bureau of Sanitation at the Fukishima Prefectural Office, after conducting an investigation of the relevant information, to take necessary measures, such as identifying the provider of these samples and places where the same lots were distributed and banning sales based on the Food Hygiene Law.
We now have continuous online access to data from CTBTO radionuclide monitoring stations, which is being evaluated by Agency dosimetry specialists.
As far as the Fukushima Daini nuclear power plant is concerned, there is no record of any incidents or radiation releases at the site. Present elevated radiation levels at the Daini site are attributed by Japan to events at the Daiichi nuclear power plant.
