Fukushima-Daiichi Nuclear Power Plant Accident in Japan INFORMATION BULLETIN No. 12 (24 March 2011 Update as of 2:00 PM)
Details
The DOST-PNRI continues to closely monitor the situation at the Fukushima-Daiichi Nuclear Power Plant. The situation remains serious but stable with some progress in restoring electrical power and instrumentation.
According to the IAEA, there has been little change in reported radiation levels on-site since 22 March 2011. The deposition of Iodine-131 and Cesium-137 varies across some 10 Prefectures from day to day, but the trend is generally upward. In contrast, environmental radiation monitoring data in the Fukushima Prefecture outside the 20-km evacuation zone shows mostly decreasing values.
Radioactive iodine has been detected in Tokyo tap water in levels above the limit for infants but below the level for adults. The Tokyo Metropolitan government says 210 becquerels of Iodine-131 were detected on Tuesday in one liter of water at one of its purification plants in northern Tokyo. This level is above the 100-becquerel limit for infants. Tokyo says infants in the central 23 wards, plus 5 adjacent cities, should refrain from drinking tap water. It is also urging beverage makers in these areas not to use tap water in infants drinks. Japanese authorities added that the safety level assumes long-term consumption, and that there is no risk to health if tap water is consumed over a short period.
The Philippine Food and Drug Administration (DOH-FDA) in coordination with the DOST-PNRI briefed importers of food products and raw materials from Japan regarding the random sampling procedures to check the level of contamination of said imported items; analysis will be done by the DOST-PNRI.
There is continuous screening for radioactivity of container vans and cargo from abroad using radiation portal monitors at the Port of Manila.
