RAD REPORT: India Bans Seafood from Japan; Plant Radiation Off the Chart

Edited by Tony Rutherford from Multiple Reports

Japanese broadcaster NHK has confirmed that the government withheld release of data which indicated that radiation levels more than 30 km from the crippled plant exceeded safe levels. Low levels of radioactive material have also been detected in other countries including the US and Britain.

According to the Uztbekistan News, school playgrounds in and around Fukushima are being checked for radiation after some readings came back high.

RADIOACTIVE WATER STOPPED?

Toyko Electric Power stated that as of 5:38 a.m. April 6, “we observed the stoppage of the water spilling from the crack on the concrete lateral of the shaft made of concrete” at Reactor Unit 2. The apparent blockage of the radioactive water came after placing a tracer in the holes and injecting a”coagulant.” The Japanese used 400 gallons of sodium silicate to stem the flow of the water.

“We will continue the countermeasure in order to prevent further outflow

of high level radioactive materials to the ocean,” the TEPCO release concluded.

 

On April 4 TEPCO reported , “There is currently great amount of radioactive waste water in the turbine  buildings of the Fukushima Daiichi Nuclear Power Station and especially  the turbine building of Unit 2 has extremely high level radioactive waste water. We have decided to discharge to the sea [Pacific Ocean] approximately 10,000 tons of accumulated low level radioactive water and 1,500 tons of low level radioactive subsurface water.

Regarding the effect on seafood, TEPCO surmises, “We evaluate approximately 0.6 mSv of effective radioactive doses per year  for adults as the impact on the discharge of the low radioactive waste  water to the sea if they eat adjacent fish and seaweeds every day. The  amount (0.6 mSv of effective radioactive doses per year) is one-fourth of annual radioactive dose to which the general public is exposed in nature.   FISHING SUSPENDED However, the release translates to 7.5 million times the legal limit of iodine 131 detected in ocean waters near the crippled facility. NHK reports that fishery cooperatives in Ibaraki (located south of the Fukushima plant)  are suspending all fishing activities, after small fish caught in waters off its coast were found to contain radioactive cesium above the legal limit.  India has become the first country to ban all food imports from Japan.


Earlier this week, 526 becquerels of radioactive cesium, exceeding the legal limit of 500, was detected in one kilogram of the small fish called sand lance caught in seas off northern Ibaraki.
  PLANT RADIATION LEVELS  BEYOND MEASUREMENT (FROM NHK World News) A radiation monitor at the troubled Fukushima Daiichi nuclear power plant says workers there are exposed to immeasurable levels of radiation.
GUAM FREE OF HARMFUL RADIATION


The monitor told NHK that no one can enter the plant's No. 1 through 3 reactor buildings because radiation levels are so high that monitoring devices have been rendered useless. He said even levels outside the buildings exceed 100 millisieverts in some places.

Pools and streams of water contaminated by high-level radiation are being found throughout the facility.

The monitor said he takes measurements as soon as he finds water, because he can't determine whether it's contaminated just by looking at it. He said he's very worried about the safety of workers there.

Contaminated water and efforts to remove it have been hampering much-needed work to cool the reactors.

 

The Guam Office of Civil Defense & the Guam Environmental Protection Agency report that air and water around the island continues to be free of any harmful levels of radiation from the Japanese nuclear disaster.

The Guam Department of Homeland Security Office of Civil Defense reports that radiation spilling into the Pacific Ocean in Japan poses no threat to Guam.

And Guam EPA reports that results from a detailed filter analyses from the RadNet air monitor near the Governor’s House – along with 11 others throughout the United States – have stated radiation levels continue to fall within normal levels.  

Results from the test at www.epa.gov/japan2011 show radiation for Guam has measured below 0.01 since the sensors were installed on March 19. Background external exposure rates typically range between 0.005 and 0.020 millirem per hour (mR/hr) - levels that are thousands of times below any conservative level of concern.

“The radiation spilling into the water (in Fukishima, Japan) is a localized incident,” said Alyssa Benito, public affairs officer for the GHS Office of Civil Defense. “Fortunately, our distance from Japan is our biggest protection. Any release of radiation will be diluted before it reaches Guam or the waters surrounding Guam.”

 
As a result, the federation of fisheries cooperatives in Ibaraki decided to stop fishing sand lance, while allowing each cooperative
