Today’s NHK news regarding status of Fukushima Daiichi nuclear power
station as of 12:00 on March 29
●Tokyo Electric Power Company says plutonium has been found in soil
samples from the Fukushima Daiichi nuclear power plant.
It says the radioactive substance appears to be related to the ongoing nuclear
accident, but the level detected is the same as that found in other parts of
Japan and does not pose a threat to human health.
TEPCO collected samples from 5 locations around the power plant over 2
days from March 21st and found 2 samples contaminated with plutonium.
Plutonium is a byproduct of the nuclear power generation process. At the
number 3 reactor of the Fukushima plant, plutonium is an ingredient in mixed
oxide, or MOX, fuel.
Radioactivity from plutonium can be shielded by a sheet of paper. But it can
remain in lungs and other organs to cause long-term damages including cancer.
The Nuclear and Industrial Safety Agency says the detected level is the same
as that found in the environment and not health-threatening for workers who
conducted the sampling, nor residents in surrounding areas.
The agency said it is awaiting the results of another survey by the Science
Ministry outside of a 20-kilometer radius from the plant, as well as a further
survey by TEPCO in the plant compound.

●TEPCO faces challenge in cooling reactor
The Nuclear and Industrial Safety Agency said on Monday that TEPCO has to
strike a balance between injecting cooling water into the reactors and
preventing radioactive water from seeping out.
On Monday, the power company detected radiation of more than 1,000
millisieverts per hour on the surface of puddles in the No. 2 reactor's turbine
building and in a trench outside the building.
The concrete trench stretches toward the coast but does not connect to the sea.
Puddles of water were also found in the trenches of the No.1 and No.3
The No.1 reactor's trench will overflow if the water rises by 10 centimeters.
TEPCO has blocked the trench outlet with sandbags and concrete to prevent
the water from reaching the ocean.
The water in the trenches of the No.2 and No.3 reactors is reportedly 1 meter
We have been reporting a status of Fukushima Daiichi nuclear power station by
summarizing news aired by NHK, which is Japanese national broadcasting company.
We regard it as most credible news among many news sources and I am happy to say
that NHK’s English website has gotten enriched and you can see movies and English
scripts at www3.nhk.or.jp...
Given this situation, we decide to simply place these scripts as it is for the record in case
that it will be deleted later, rather than summarizing news as we did.
TEPCO said it hopes to swiftly find a way to remove the water from the
On Monday, The power company scaled back its operation to cool the No. 2
reactor, injecting 7 tons per hour, reduced from 16. The reactor's temperature
rose by more than 20 degrees Celsius.

●Radioactive water in external tunnels
The operator of the damaged nuclear power plant in Fukushima, northeastern
Japan, has reported that very high levels of radiation have been observed in water
in a trench just outside the turbine building for one of the reactors.
Tokyo Electric Power Company announced on Monday that a puddle of water
was found in a trench outside the No. 2 reactor turbine building at the Fukushima
Daiichi nuclear plant on Sunday afternoon. It said the radiation reading on the
puddle's surface indicated more than 1,000 millisieverts per hour.
The concrete trench is 4 meters high and 3 meters wide and houses power cables
and pipes. It is located in the compound of the plant but outside the radiation
TEPCO says the trench extends 76 meters toward the sea but does not reach the
sea, and that the contaminated water was not flowing into the sea.
TEPCO says it is trying to find out how the contaminated water came to be in the
Radiation levels of more than 1,000 millisieverts per hour were recorded on
Sunday in a puddle of water in the basement of the No. 2 reactor turbine building.
Puddles of water were also found in the trenches outside the No. 1 and No. 3
reactors. TEPCO reported 0.4 millisieverts of radiation on the surface of the
puddle in the No. 1 reactor's trench. But it said it failed to measure the No. 3
reactor's trench because it was covered with debris.
TEPCO says it had no intention of concealing data regarding the high level of
radiation detected on Sunday outside a turbine building at its Fukushima Daiichi
TEPCO Vice President Sakae Muto said at a news conference on Monday that he
only received the report from the plant workers earlier in the day.
The plant operator has revealed that it found water in a covered tunnel outside
the turbine building of the number 2 reactor, and that radiation of more than
1,000 millisieverts per hour was detected in the water.
Muto said the company has made this public and instructed the plant workers to
quickly take steps to dispose of the water.
Asked by reporters if TEPCO was concealing information, Muto said the
company has no intention of doing so.
He also said every day is full of events, and that TEPCO will quickly share
information of high importance so that it can swiftly consider countermeasures.
Vice President Muto added that the plant operator will confirm the flow of
information and have it thoroughly implemented in order to avoid

●Radiation hampers cooling efforts
The effort to cool reactors at the damaged nuclear power plant in Fukushima,
northern Japan, is facing the risk of leaking highly radioactive substances.
The plant's operator, Tokyo Electric Power Company, raised water pumping
power on Sunday to cool the No. 2 reactor in a stable manner. On Monday, the
company cut back on the amount of injected water.
The move followed the Nuclear Safety Commission's announcement that highly
radioactive substances detected in puddles of water in the basement of the
reactor's turbine building may have come directly from the vessel containing the
16 tons of water was being injected into the reactor every hour but TEPCO now
says it wants to reduce the amount to 7 tons. This would be enough to replace the
amount that is evaporating.
If the injected water level is reduced, temperatures may increase in the reactor.
TEPCO announced on Monday that radioactive substances 100,000 times higher
than usual for water in a reactor core were detected in puddles in the No. 2
reactor's turbine building on Sunday.
High radiation figures were also recorded earlier in water in the basements of the
turbine buildings for the No. 1 and No. 3 reactors. On Thursday, 3 workers were
exposed to high radiation while working in water at the No. 3 reactor's turbine
The Nuclear Safety Commission said on Monday that the concentration of
radiation at the No. 2 reactor was dozens of times higher than the other 2 reactors.
The commission said it assumes that radioactive substances from temporarily
melted fuel rods at the No. 2 reactor had made their way into water in the reactor
containment vessel and then leaked out through an unknown route.
TEPCO, later, reported that very high levels of radiation have also been observed
in water in a trench just outside the turbine building for one of the reactors.
The commission said the biggest concern is the possibility of highly radioactive
water seeping into the ground and the ocean. It added that all-out efforts should
be made to prevent contaminated water from leaking and called on the
government to intensify monitoring radiation levels in the ground water and

My money is still on them pumping everything from the buildings, the trenches, etc. into the ocean. The question is, will they tell us about it before they do it, or after they have done it.
I think it is obvious there is a cover up going on here and in the US regarding the true radiation levels.
Traces of radioactive iodine, cesium detected in S. Korea
The radiation level poses no risk to public safety and the environment, the ministry said.
Radioactive iodine has been detected in 12 radiation stations nationwide, including Seoul, while cesium was found only in Chuncheon, 85 kilometers west of Seoul, Yonhap News Agency reported Tuesday, citing the Korea Institute of Nuclear Safety.

UPDATE: a Berkeley lab's results from testing rainwater on March 23rd suggests that 1 liter of rain-harvested drinking water in Berkeley, Calif., would have an iodine-131 concentration of 542.7 picocuries and consuming one liter of this water would provide a radiation dose to the thyroid of an infant of 7.54 millirems. About 132 liters of water contaminated at these levels would provide 1 Rem dose to the infant thyroid. (Per NRC NUREG 1.109 rev. 1 Oct. '77). At these levels, a Bay Area adult would have to breath for 425 days to receive the same iodine-131 exposure as drinking 1 liter of rain-harvested drinking water. Also, the cesium-137 levels in rain water for March 23-24 broke a new high record peak since analyses begin on March 17 at the Berkeley lab - it's now at 16 picoCuries of Cesium-137 per liter of rain-harvested water. Boil down a liter of this rainwater, or ash in an oven a rain-soaked 'sticky' film filter, and it would measure on an advanced gamma counter 1,344 clicks per minute (CPM) *above* normal background levels - that doesn't even include the beta or alpha particles, including the beta energies of the Iodine-131 and Cesium-137!
