Headline from Enenews: Experts Warn of Accumulating Fukushima Radiation
Title: The muddy issue of cesium in a lake
Source: Japan Times by Tomoko Otake Nov 18, 2012 http://www.japantimes.co.jp/text/fl20121118x3.html
[Excerpted] Lake Kasumigaura in Ibaraki Prefecture is facing an environmental threat that has essentially turned it into a time bomb ticking away 60 km northeast of Tokyo.
Experts warn that Japan’s second largest lake with a surface area of 220 sq. km is quietly but steadfastly accumulating radioactive cesium [...] [It] is not only rich with fishery resources but whose water is used for irrigation, industrial purposes, and even for consumption as drinking water for 960,000 people in Ibaraki Prefecture. Furthermore, no one knows how and by how much the problem has worsened over the months, except for one obvious thing: it hasn’t gone away. [...]

NO THRESHOLDS FOR EFFECTS

Even Low-Level Radioactivity Is Damaging, Scientists Conclude. Science Daily. November 13, 2012 http://www.sciencedaily.com/releases/2012/11/121113134224.htm
[Excerpted] The organisms studied included plants and animals, but had a large preponderance of human subjects. Each study examined one or more possible effects of radiation, such as DNA damage measured in the lab, prevalence of a disease such as Down's Syndrome, or the sex ratio produced in offspring. For each effect, a statistical algorithm was used to generate a single value, the effect size, which could be compared across all the studies.
The scientists reported significant negative effects in a range of categories, including immunology, physiology, mutation and disease occurrence. The frequency of negative effects was beyond that of random chance.
"There's been a sentiment in the community that because we don't see obvious effects in some of these places, or that what we see tends to be small and localized, that maybe there aren't any negative effects from low levels of radiation," said Mousseau. "But when you do the meta-analysis, you do see significant negative effects."
"It also provides evidence that there is no threshold below which there are no effects of radiation," he added. "A theory that has been batted around a lot over the last couple of decades is the idea that is there a threshold of exposure below which there are no negative consequences. These data provide fairly strong evidence that there is no threshold -- radiation effects are measurable as far down as you can go, given the statistical power you have at hand."
Mousseau hopes their results, which are consistent with the "linear-no-threshold" model for radiation effects, will better inform the debate about exposure risks. "
CHILDREN IN FUKUSHIMA AND ELSEWHERE AT RISK
blogger Ex-SKF reports #Radioactive Japan: Another Child Suspected of Thyroid Cancer in #Fukushima, Found During the First-Round Thyroid Screening Test
Nov 17, 2012 [excerpted]: Kyodo News just reported it was a girl, age 16 to 18. The first confirmed case of thyroid cancer in a child in Fukushima Prefecture was reported in September this year, after the 2nd screening test which was administered as a precaution.
Possibly the second one may have been found, according to Kahoku Shinpo. What's different in this case is that the child was immediately categorized as "C" in the 1st round of screening. Category C is " in need of immediate second testing", according to the Fukushima prefectural guideline.
