May Link Dump - Fukushima

It's actually September, reader. These are some post-dated(?) posts. I tend to throw links up on FB, where they could be read by a few dozen people, and which can be easier than Blogger, altho limited and perishable. I am picking a few links and skipping the handful of news items (mostly Fukushima-related) that I post more or less daily.

New Work Reinforces Megaquake's Harsh Lessons in Geoscience

High-tech analyses of Japan's March earthquake overturn long-held views of fault behavior and warn that another disaster may be looming.... Simons and colleagues see “the possibility of a sibling to the 2011 event” that could be “similar to what just occurred offshore,” but half as far from Tokyo. So researchers are anxious to find out whether the stress transferred southward from the 9 has accelerated slow slip on the fault and thus defused the threat of a quake.
Schoolyard Radiation Policy Brings a Backlash
The Japanese government's most controversial misstep in response to the Fukushima nuclear power plant crisis may have been the release of guidelines on allowable radiological contamination in schoolyards.
The education ministry calculated that children could spend 8 hours a day in a schoolyard exposed to as much as 3.8 microsieverts per hour, and 16 hours a day indoors exposed to 1.52 microsieverts per hour, and not exceed the 20-mSv limit.

Fukushima Revives The Low-Dose Debate
The general public avoided exposure to high levels of radioactivity, but questions linger about the long-term effects of contamination.
Across Fukushima and neighboring prefectures, small amounts of cesium-134 and cesium-137, isotopes with half-lives of 2 and 30 years respectively, lie on the ground. Cleanup workers have stripped contaminated topsoil from some schoolyards, and remediation or permanent evacuation is likely for the worst areas.

Radiation Monitoring Data from Fukushima Area 05/13/2011
In March, the U.S. Department of Energy released data recorded from its Aerial Measuring System as well as ground...
Includes radiation measurements for the Shinkansen route from Tokyo to Sendai between and at stations.
The 60 billion yen project on a vacant 19-hectare site of a former Panasonic plant will see the construction of 1,000 homes as well as various facilities that will be powered using solar power generation and home-use storage battery systems, the consumer electronics giant said. The planned town, called Fujisawa Sustainable Smart Town, will also promote the sharing of electric vehicles.
