As of today(13th April), an aftershock occurred at midnight of 7th Aril was the biggest one.
This magnitude 7.1 aftershock made two different nuclear plant's cooling system stop for a while.
One is Onagawa nuclear plant.
http://www.tohoku-epco.co.jp/genshi/onagawa/index.html
This facility has 3 reactors
The other is a Higasidohri nuclea plant.
http://www.tohoku-epco.co.jp/genshi/higashi/index.html
This facility has 1 reactor.
All of them are under suspension after devastating 311 earthquake. Some of them are under suspension before the earthquake because of maintenance.
By the way, I have learned this, it is just a little complicated.
Reactors have to be kept cool when they are under suspension. In order to run the cooling system, electric power which is independent from the nuclear power plants is must.
Fukushima nuclear plant accident was triggered by the lack of electric power for cooling system. Earthquake destroyed the electric cable which bring external electric to the nuclear plant, Tunami carried diesel fuel tanks for power generator.
The reason of stopping of cooling system at Higasidohri nuclear plant is reported that one part of generator's pump was assembled in the wrong way.
There are a lot of committee, foundation, etc. etc. which declare they are founded for nuclear safety and they are receiving substantial money. Even if the committee and foundation know very well about highbrow nuclear plants, they look not to be interested in last hope generator.

eating show
Spinach and milk were announced in which radioactive materials were found at 19th March, one week after the accident.
We Japanese had new guideline about radioactive food two days before this announce. The new interim guideline is very different from that of WHO.
Currently radioactive things are found in many food already. Some values are lower than interim guideline, that mean these food are safe, according to the government. If I were 70 years old, I would happily eat these discounted delicious food. Because effect of radioactive food is told to appear 20 years after or so. But it seems many consumer don't want to purchase such a "safe" food, especially mothers of young children and babies.
To encourage consumer, diet members make us watch they are eating these food often. Both members of ruling party and opposition party are equally similarly eating eating eating.....

TEPCO's ad is back on TV screen
TEPCO is a only company that provide electric power in Tokyo. In spite of no business rival, TEPCO was spending a lot of money to ad. It has been told that as TEPCO is a big client for TV company, TV persons don't accuse TEPCO. Many celebrities were saying nuclear was safe, clear and necessary in the ad before.
I saw TEPCO's ad yesterday first after Fukushima nuclear power plant accident. No celebrities. only narration and text in the screen says sorry for this anxious, inconvenience, etc..
It seemed to be very very clear that TEPCO will have to pay huge compensatory payment to numerous people. I don't understand how they are spending money only to say sorry for this inconvenience.....

help-wanted ad $85 per hour, no experience required
According to the zakzak, which is a sort of gossip paper, a temporary staff service was looking for 10 workers. That job is payed 10,000 yen per hour (about $85 per hour). No qualification, no experience required. Duty station is Fukushima prefecture, job description is cleaning in the nuclear power plant. The ad was posted end of March and the temporary staff service could happily find 10 works already.

I am looking for a bottled water
A month after the earthquake, tap-water in Tokyo shows much radioactive materials level than that of drinkable water suggested by WHO.
Unfortunately I could not find bottled water today in the shops. After earthquake I could purchase only one 2-litter bottled-water. It is not easy to find bottled-water which is seemed to free from radioactive things. As I don't want to drink tap water, I have been purchasing small amount bottoed-water, which is about 3 times higher price than gas. I could not even find it today.
By the way, I have heard that one of the reason of this water shortage is, bottled water packs are sending to refuges. it is priority of course. some area don't have tap water still now, one month after the earthquake.
Secondly, the earthquake destroyed many plants, besides shortage of electric power, many plants can not run as usual. Especially one maker of lid part of plastic bottle has been affected badly. That become a literally bottle neck.

radioactive fallout
Air, water and "fallout" are reported every day in Japan.
Radiation is emitted from radioactive materials. Radioactive materials originated from nuclear plant explosions are ... sort of very small dust. I think... They are carried by wind and fall on the ground, roof, vegetable... anywhere.
Tokyo is more 200km away from Fukushima nuclear plants, the wind was flowing toward to the sea when plants exploded, so radioactive materials seemed to take a few days from Fukushima to Tokyo.
When we had rain, lots of dust in the higher place in the air fell with rain.
So after rain, radioactive material levels showed higher number.
Unfortunately we can not get away from these dust. We can breath radioactive materials in the air and and keep them in lung, we can drink the water containing radioactive materials, we can eat vegetable on which radioactive materials stick. So do livestock. So do fish. Thus creature of top of food chain can ingest condensed radioactive food.
By the way, I purchased a lot of mask before earthquake as a preparation of hay fever season. I have pollen allergy like typical Japanese. I heard radioactive materials are bigger than virus and smaller than pollen. (I am looking for technical trustable data about this.). So mask for virus will be helpful to reduce inhalation of radioactive materials.
My masks don't work for reducing radioactive materials, but pollen allergy people know how to reduce the effect of fallout. I heard following way are effective, at least they would bring better result than do nothing. Radiation is invisible and it will show their aftermath after 10 years, 20 yeas ...... But pollen allergy people detect immediately pollen existence by one's snotty nose, eye itch, etc. etc....
don't open wind too much
clean up the dust on coat before coming into the house
take shower
wear appropriate mask
wear appropriate glasses

contaminated water
Tap water in Tokyo includes radioactive material.
As of April 4th, their values are better than WHO guidance level under bad condition, and worse than WHO guideline for desired condition.
Radioactive materials in tap water was detected 3/16, near place to the Fukushima nuclear plant.
(earthquake 3/11, the first explosion of reactorNo1 was 3/12, reactorNo3 explosion was 3/14, explosion of reactorNo2 and reactorNo4 was 3/15)
So, purification plant in Tokyo started reporting radioactive material revel 3/17.
According to this pdf document;
http://www.who.int/water_sanitation_health/dwq/GDW9rev1and2.pdf
(page 203), WHO guidance level are:
Iodine-131 10Bq/litre
Cesium-134 10Bq/litre
Cesium-137 10Bq/litre
According to this page by purification plant in Tokyo;
http://www.metro.tokyo.jp/INET/OSHIRASE/2011/03/20l3i200.htm)
WHO has another much strict guidance level;
The purification plant says they had been keeping good level last 20 years before 3/17 also.
Current Japanese guicance level which was issued 3/17 are 30time higher than WHO's value:
http://www.mhlw.go.jp/stf/houdou/2r9852000001558e-img/2r9852000001559v.pdf
Iodine-131 300Bq/Kg
Radiocesium 200Bq/Kg
As Japanese have new guideline, almost all water is SAFE in Japan, Japanese government don't have to notice how much water is contaminated.
Japanese had the same guidance level as WHO before, maybe.

alpha-radioactivity 0.5Bq/litre
beta radioactivity 1Bq/litre
