Heavy
rains overflow barriers surrounding Fukushima water tanks
.
Water
has overflowed at Japan’s Fukushima Daiichi nuclear plant. Tokyo
Electric Power Company (TEPCO) is attempting to discern the quality
of the water and possible radioactive substances which could have
been spilled.

Heavy
rains caused water to flow over the barriers of an artificial
embankment which surrounds a dozen tanks of radioactive water at
the plant. TEPCO reported that liquid containing a source of beta
radiation was found beyond the levees.
The
company said the incident was “due to heavy rain in the Tohoku
region.” Company specialists are attempting to identify the
amount of leaked water and the radiation levels present in the
liquid.
Radioactivity
levels in a well near a storage tank at the Fukushima nuclear
power plant have risen immensely, the plant’s operator earlier
reported, fueling ongoing concern about the impact of radiation on
the surrounding environment.
Last
Wednesday, heavy rains brought with Typhoon Wipha caused
reservoirs for collecting rainwater to overflow. The natural
disaster was described by weather forecasters as the strongest in
a decade, leaving at least 17 people dead and 50 others missing in
its wake.
Workers
at the Fukushima plant had to pump rainwater out of protective
containers surrounding approximately 1,000 tanks holding
radioactive water. It is thought that the heavy rains lifted
contaminated soil.
Shortly
afterwards, radiation levels were found to have skyrocketed. TEPCO
officials said Friday that they detected 400,000 becquerels per
liter of beta ray-emitting radioactive substances - including
strontium - at the site of a well near a storage tank. The level
was 6,500 times higher than readings taken Wednesday, according to
NHK World.
The
news showed that radioactive substances like strontium have
reached the groundwater, according to the officials. In August,
the same storage tank leaked over 300 tons of contaminated water.
Earlier
this month, TEPCO announced that 430 liters of polluted water had
spilled from a tank as the company’s employees tried to remove
rainwater dumped at the plant by recent typhoons. The contaminated
water may well have flowed into the sea, TEPCO said.
However,
estimates still may be unreliable. The UN Scientific Committee on
the Effects of Atomic Radiation (UNSCEAR) raised doubts at the
beginning of the month. A preliminary report published in the
Japanese press concluded that estimates of radioactive substances
discharged at the plant provided by the Japanese authorities,
TEPCO, and other entities may have underestimated the impact of
the disaster.
The
power plant was disrupted in March 2011 by a massive earthquake
and tsunami which wreaked havoc at Fukushima and sparked a nuclear
crisis in which meltdowns occurred in three reactors. It was
considered to be the world’s worst nuclear accident since the
Chernobyl disaster in 1986.
In
September, a senior utility expert at Fukushima, Kazuhiko
Yamashita, said that the plant was “not under control.” TEPCO
downplayed his comments, saying that he had only been talking
about the plant’s waste water problem – not the facility as a
whole.

US Pacific Coast Seaweed Shows With Fukushima Cesium Contamination
19
October, 2013
New
testing done by Worcester Polytechnic Institute, Dept. of
Civil and Environmental Engineering found Fukushima cesium in US
Pacific sea weed. The samples were standardized against a known
amount of cesium 137 and cobalt 60. The finding of cesium 134 would
indicate this is at least partially from the Fukushima nuclear
disaster.
“Washington
State Pacific coast eel weed sample contained 0.22 pCi/g of
Cs134 and 0.24 pCi/g of Cs137. It also contained 0.1 pCi/g of
Co60”
These values converted to the more common bq/kg are:
These values converted to the more common bq/kg are:
Cesium 134: 8.14 Bq/KgCesium 137: 8.88 Bq/KgCobalt 60: 3.7 Bq/Kg
They
also tested nori sheets from a market in Chiba prefecture Japan.
“One
of two Japanese nori samples from a Chiba Prefecture market contained
1.1 pCi/g of Cs134 and 1.7 pCi/g of Cs137. (That’s 41 and 63
Bq/kg, respectively.) The other was nondetect for these
isotopes.”

News 10/20/13: Radioactive Leaks From 12 Barriers; Super Typhoon
Heads For Japan
I have no way of interpreting what this is about.
Mike Ruppert comments: “We know what it is. It's one of the cooling towers near Bldg 4. But all I can make out is rain. We know the tower has ripped loose from some supports and appears to be leaning”
Alert!!! 10/20/13 Big Trouble at Fuku and the world?
