Tritium level also high in Fukushima trench water


Tokyo Electric Power Co. said Sunday it had detected a high level of tritium in water under its stricken Fukushima No. 1 power plant.

Tepco detected 8.7 million becquerels of tritium per liter in water taken Friday from a cable trench running under the turbine building of the No. 2 reactor at a point about some 50 meters from the Pacific Ocean. The reading is 145 times the legal limit.

While tritium is a common hazard at nuclear power plants, the revelation came a day after the utility announced that the same water sample contained 2.35 billion becquerels of cesium and 750 million becquerels of other, unnamed radioactive substances, including strontium, that emit beta rays.

All would likely pose a higher risk of cancer if ingested by humans.

Tepco has been unable to figure out why the groundwater is being tainted with radiation. Its latest theory appears to be that the water in the observation wells on its premises is being tainted by water from the cable trench.

Last week, Tepco admitted that groundwater tainted with radioactive substances leaked into the Pacific from the plant and that the water level in the wells was rising and falling with the ocean tides.

    This is the most critical issue for humans worldwide. Everyone everywhere especially the Japanese should and must devote every ounce of effort eradicating the problem, or else!

      The radioactivity can only get worse with time. The containment will be tested over and over as what was secure becomes insecure. When this earthquake/tsunami hit, it seriously fractured the concrete holding the plant together. Add a nuclear meltdown, runaway entering ground water, and you have a recipe for disaster. Like the article says, in this case they believe the contamination is seeping out through electrical conduits, and there are many. That’s not including all the fracture spots which are innumerable to count. This reminds me of children running through a freshly mopped wet kitchen with muddy feet. It is spreading everywhere. It will spread and spread and spread until all of japan has some nuclear poison in their midst.

        hey about 5 more years and chernobyl will be safe for humans to visit. not to live in but just to visit. and for japan? maybe 36 years….

    And still there is no radiation problem at Fukushima……

    Everyone says to stop the radiation, its not like they are doing it on purpose.

    Tepco’s “latest theory appears to be that the water in the observation wells on
    its premises is being tainted by water from the cable trench.” – indeed? And may we ask how the tainted water gets into the cable trench?
