RADIATION DOSE RATES CONTINUOUSLY SHOWING DOWNWARD TREND

KUALA LUMPUR, April 21(Bernama) -- The International Atomic Energy Agency (IAEA) has confirmed that Radiation Dose rates at all locations of the Fukushima Daiichi Nuclear Power Station have shown a continuing downward trend since April 1.

Science, Technology and Innovation Minister Dr Maximus Ongkili said
according to the levels measured on April 18, involving 47 districts, Ibraki registered 0.13 micro-Sievert per hour while Fukushima recorded 1.9 micro-Sievert per hour.

"The other 45 prefectures had dose rates within the typical background range of 0.05 to 0.1 micro-Sievert per hour," he said in a statement here Wednesday.

On April 16, the restriction on distribution of raw unprocessed milk produced in 25 areas of Fukushima was lifted, and on April 17, the restriction on the distribution of Kakina, parsley and spinach produced throughout Ibaraki prefecture was lifted.

On Tuesday, the modeling results by the Environmental Emergency Response Centres (EER) of WMO predicted that the tracers of radioactive Iodine 131 released from Fukushima Nuclear Power Station will be transported south eastwards, and expected to turn south and over to the central part of Japan for the rest of the forecast period until April 22.

The exposure and deposition areas of the tracers will cover part of northern and central Japan, the northwestern part of the Pacific and northern part of sea of Japan, he said.

The IAEA had Tuesday confirmed the use of unmanned robots to inspect the condition inside unit 1, 2 and 3 of the nuclear plants at the Fukushima Daiichi Nuclear Power Station.

The use of robots will reduce the exposure of emergency workers to
radioactive contaminants while the removal of rubble was carried out using remote-control heavy machineries, and as of Monday, 10 containers of rubble were removed.

The amount, 60,000 tons of radioactive water from Units 1, 2 and 3 will be transferred to the condenser and the Radioactive Waste Treatment Facility.

In addition, temporary storage tanks have been prepared and they will be located adjacent to the Radioactive Waste Treatment Facility.

The owner of Fukushima Daiichi Nuclear Power Station, Tokyo Electric Power Company (TEPCO), has submitted a plan to transfer the stagnant waste water which is highly contaminated from the basement floor of the turbine building of Unit 2 to Nuclear and Industrial Safety Agency (NISA).

The waste water will be transferred to the Main Building of Radioactive Waste Treatment Facilities. The aim of transferring the highly contaminated water is to reduce the risk of it seeping to the environment.

Meanwhile, the monitoring of radioactive contaminants using the
Environmental Radiological Monitoring System (ERMS) that are located in 6 sites throughout Malaysia (Chuping, Ipoh, Kuantan, Senai, Sri Aman and Kudat) continued to show normal levels that are safe for public, he said.
