Reliable data V theoretical data and sludge.

If you want the truth (reliable living data not theoretical data), ask the University professors. Especially those active in research. This is a country (like others) where education is so important and so highly prized and respected that Universities still attract some of the countries best scientific brains and some amazingly brilliant people. They are also very well funded and have the finest labs and state of the art equipment there is and most importantly no financial gain political agenda.This is where some of the best and most accurate data and info is coming from now, re-safety and risk evaluation in the Fukushima aftermath.

So was really pleased to learn today that a team of University professors have teamed up to seek the truth of exactly what has happened at all the reactors and that this independent probe will be one that has no invested interest in nuclear power.

Professors are also joining forces to test vegetables and local produce here to cover a wider area than govt led testing can handle.Many professors are also involved in volunteer charity work up here like this man:

Meanwhile at the plant, a possible melt through confirms what everyone suspected anyway, that the groundwater issue will be the most serious long term obstacle for people living outside Fukushima. Growing food in contaminated soil. Radiation levels have peaked and are for now declining outside the area. Fall out is still the big concern up here with rainy season on its way. How melt through affects farmers and crops is going to pan out as main news next. So far, it is being said that soil will hold fall out particles only in the top 10cms meaning it may be possible for farmers in Ibaraki and surrounding Fukushima areas to change crops and grow things that are either very deeply rooted and less absorbent like fruit trees or to consider transfer values and manage soil accordingly.

Transfer values include: type of soil, temperature, rainfall and wind as well as the basic structure of the plant. Osmotic effect is more in vegetables that have thin wide leaves like...spinach.Under present sanitation laws
the limit for radioactive cesium for farm produce is set at 500 becquerels per kg of soil. Hopefully the govt isn't going to suddenly raise this. Knowing which areas of soil are "clumping" nuclides (as they fall in clumps) via testing can help farmers keep some soil safer. Building glasshouse/greenhouses over safe soil, topsoiling etc. Farmers are very worried as are fishermen that their livelihoods are in serious danger. Fukushima Fishermen held a protest the other day on any more low level radioactive water being allowed into the sea. Soil and water problems need attention asap. Farming and fisheries are top industries.

Then there is the sludge. Apparently cesium was found at high levels in sewage sludge in Tokyo bay, Saitama, Kawasaki and Ibaraki.Disposal units and re-cycling centers rightly refuse to take the sludge (which is usually made into cement)fearing radioactivity. Sewage sludge is building up and there is no place to store it. This adds to the huge coastal rubble disposal issues..nowhere for that either and it is not sanitary to just leave it.
