Human Radiometer Birdhairjp

Birdhairjp visits the three cities of Koriyama, Nihonmatsu, and Fukushima to conduct radiation measurements at elementary schools and public parks 55 to 60 km from Fukushima Dai-Ichi as the cherry blossom front moves through. Past measurements have been made in many places, including Namie (65μSv/h), Kashiwa (9μSv/h) and Tokyo (2.35μSv/h at Minami-Katsushika H.S.).

The results at ground level are horrible. Although these may be hot spots, they are in public areas. The results at chest height (1.4, 0.81, 0.56μSv/h) are not terribly good either.

Breaking down the environmental radioactivity monitoring data from MEXT (Ministry of Education, Culture, Sports, Science and Technology and whatnot)

As reported in the Asahi:

The science ministry has begun posting real-time radiation levels on its website at 2,700 locations across Fukushima Prefecture, including schools and parks.
To access radiation levels measured at 10-minute intervals, go to http://radiomap.mext.go.jp/ja/.

Checking out today's data at
http://radioactivity.mext.go.jp/map/ja/area.html

Let's do some math...

Consider the maximum acceptable radiation dose for the public from any man-made facility: 1 mSv/year.
1 mSv/year is 1000 μSv/year.
1000 μSv/year is 0.114 μSv/h.
(Based on 8766 hours in a year (24×365.25) and 1000 microsieverts(μSv) in a millisievert (mSv).
Therefore any place with over 0.114 μSv/h is questionable.

Japan set a limit 20 times higher, 20mSv/year, for Fukushima residents.

Residents exposed at that level would reach the 350 mSv/lifetime limit which was used to determine evacuation areas after the Chernobyl disaster within 18 years.
Using the Chernobyl lifetime standard, calculating for a 10-year old child with an additional 70 years life expectancy, 350mSv/70years = 5mSv/year.

Recapping, the 1 mSv/year international standard is exceeded by the Chernobyl evacuation standard, which (if judged to be tolerable) could conceivably justify 5 mSv/year for kids (twice that for 35-year-olds, etc.), and that was exceeded by the 20 mSv/year Japanese Fukushima-only standard, which I believe was set at that level for political reasons only, to set a standard that would avoid the need to evacuate several large cities and partially sever northern Japan from the south and middle.

Some selected ranges of readings for locations today, Sunday, April 29, 2012:

Fukushima-ken locations:
MinamiSoma     0.080 - 5.036 μSv/h = 0.701 - 44.14 mSv/year
Fukushima City     0.092 - 1.764 μSv/h = 0.806 - 15.46 mSv/year
NihonMatsu     0.113 - 1.324 μSv/h = 0.990 - 11.60 mSv/year
Koriyama     0.067 - 1.379 μSv/h = 0.587 - 12.08 mSv/year
Sukagawa City     0.098 - 0.727 μSv/h = 0.859 - 6.372 mSv/year
Soma City     0.093 - 1.125 μSv/h = 0.815 - 9.862 mSv/year
Iwaki City     0.054 - 0.819 μSv/h = 0.473 - 7.179 mSv/year
Aizu-Wakamatsu     0.054 - 0.290 μSv/h = 0.473 - 2.542 mSv/year

Outside Fukushima-ken:
Tochigi-ken     0.036 - 0.593 μSv/h = 0.315 - 5.198 mSv/year
Miyagi-ken     0.033 - 0.367 μSv/h = 0.289 - 3.217 mSv/year
Ibaraki-ken     0.048 - 0.178 μSv/h = 0.420 - 1.560 mSv/year
Chiba-ken     0.037 - 0.172 μSv/h = 0.324 - 1.507 mSv/year
Gunma-ken     0.026 - 0.154 μSv/h = 0.228 - 1.349 mSv/year
Saitama-ken     0.027 - 0.154 μSv/h = 0.236 - 1.349 mSv/year
Tokyo-to     0.037 - 0.064 μSv/h = 0.324 - 0.561 mSv/year

If you use the lifetime-exposure evacuation standard for Chernobyl applied to children, all children should be evacuated from all of the cities measured in eastern Fukushima prefecture, with the exception of Aizu-Wakamatsu, which is more central, but which still exceeds the 1 mSv/year international standard for the nuclear power industry. Some sites in Tochigi prefecture also exceed the Chernobyl standard and should evacuate children.

All of these prefectures in the Kanto region have at least a few MEXT radiation measurement stations (which are very limited in number outside Fukushima, by the way, 5 stations in Tokyo, 7 in Chiba, etc) which record levels above the 1 mSv/year international standard. By that standard, Kanto is barely tolerable.

Numbers here in Chiba:

Home radiometry results

 after testing house for radiation October 16

Our house and garden seems to be around 0.11-0.14 microsieverts/hr, according to my friend's dosimeter. It's lower as you go up closer to the roof and eaves, not higher as with some houses. Inside is not much different than outside. We tested the sandbox in the park and at the daycare next door, and it was about the same.

He has found 0.2, 0.3, and 0.4 in Chiba. In one case a house in Matsudo had those numbers for the first, second floor, and eaves, respectively. There is a spot along the river in Noda-shi where he measures 0.4. The hot spot in Andersen Park was 0.5 microsieverts/hr. Reality is about 3 times the silly numbers the gov't reports as seen at http://www.japantimes.co.jp/radiation-levels.html

I don't really need to strip all organic material and topsoil from the garden, because it is not any more or less radioactive than the surrounding area, and it would eventually become the same anyway. And if i did collect radioactivity in my rain catchment system, it was probably radioactive iodine, which would have decayed by now. Hot spots which exist in Chiba are about 6 miles or 10k north of here.

"Contaminated Zone" in Chiba

Radiation spread reaches Chiba, Saitama prefectures - AJW by The Asahi Shimbun

» In Chiba Prefecture, the highest levels of cesium-137, between 30,000 and 60,000 becquerels per square meter, were detected in northern areas, such as Kashiwa, Matsudo, Abiko and Nagareyama. Cesium-137 has a half-life of 30 years.
In the 1986 Chernobyl nuclear accident, areas with 37,000 becquerels or more of radioactivity per square meter were designated contaminated zones, while levels of 555,000 becquerels or more required forcible relocation.
In Chiba and Saitama prefectures, the highest radiation levels were 0.2 to 0.5 microsievert per hour. In most other areas, the radiation levels were 0.1 microsievert or less.

Nuukliyur eksplouzhans 1945-1998

Japanese artist Isao Hashimoto has created a beautiful, undeniably scary time-lapse map of the 2053 nuclear explosions which have taken place between 1945 and 1998, beginning with the Manhattan Project's "Trinity" test near Los Alamos and concluding with Pakistan's nuclear tests in May of 1998. This leaves out North Korea's two alleged nuclear tests in this past decade (the legitimacy of both of which is not 100% clear).
Each nation gets a blip and a flashing dot on the map whenever they detonate a nuclear weapon, with a running tally kept on the top and bottom bars of the screen. Hashimoto, who began the project in 2003, says that he created it with the goal of showing"the fear and folly of nuclear weapons." It starts really slow — if you want to see real action, skip ahead to 1962 or so — but the buildup becomes overwhelming.

SciAM: a path to sustainable energy by 2030

http://www.scientificamerican.com/article.cfm?id=a-path-to-sustainable-energy-by-2030

Supplies of wind and solar energy on accessible land dwarf the energy consumed by people around the globe.The authors’ plan calls for 3.8 million large wind turbines, 90,000 solar plants, and numerous geothermal, tidal and rooftop photovoltaic installations worldwide.The cost of generating and transmitting power would be less than the projected cost per kilowatt-hour for fossil-fuel and nuclear power. Shortages of a few specialty materials, along with lack of political will, loom as the greatest obstacles.

You may remember this article. We are swimming in excessive energy. Solar and wind are widely distributed and cannot be as easily controlled and profitized as plutonium radioactive energy can.

A Path to Sustainable Energy by 2030; November 2009; Scientific American Magazine; by Mark Z. Jacobson; Mark A. Delucchi; 8 Page(s)

In December leaders from around the world will meet in Copenhagen to try to agree on cutting back greenhouse gas emissions for decades to come. The most effective step to implement that goal would be a massive shift away from fossil fuels to clean, renewable energy sources. If leaders can have confidence that such a transformation is possible, they might commit to an historic agreement. We think they can.

A year ago former vice president Al Gore threw down a gauntlet: to repower America with 100 percent carbon-free electricity within 10 years. As the two of us started to evaluate the feasibility of such a change, we took on an even larger challenge: to determine how 100 percent of the world's energy, for all purposes, could be supplied by wind, water and solar resources, by as early as 2030. Our plan is presented here.

Removing soil to reduce radiation at Fukushima schools

http://www.yomiuri.co.jp/dy/national/T110427006549.htm

A worker removes surface soil from school yard at Kaoru Primary School in Koriyama, Fukushima Prefecture, on Wednesday.

Hot Schools in Fukushima

http://atmc.jp/ has added a national radiation map to their existing database which includes air, soil, rain, food. They have also added a map of radiation at Fukushima Prefecture schools, http://atmc.jp/school/ as measured by the Fukushima Prefecture Disaster Office over three days, at present.

Bad news in this map is that schools in Fukushima City and elsewhere with numbers up around 4 to 6 microsieverts per hour are far above the 20 MILLIsieverts per year the govt is setting as an evacuation threshold. Do the math: Anything over 2.3 MICROsieverts an hour will accumulate to more than 20 MILLIsieverts a year. They should err on the side of caution considering: the intl standard for added dose is 1 millisievert annually, not 20; these are children, not adults; there is a possibility of ingesting and inhaling radioactive particles; and emissions and deposition levels are continuing and accumulating. They should evacuate.

One argument against evacuation is that these levels may be temporary, and go down soon, but that is doubtful. Even if so, I think they should temporarily evacuate the cities of Fukushima (290,000ppl), Nihonmatsu (61,000ppl), and Sukagawa (80,000ppl), or, if that is impossible, evacuate at least the children. Note that our levels down here in Chiba are 0.055 microsieverts per hour today, only 1% of what is measured at some of those schools. (compare to 5.5)

If the govt keep to their stated standard of evacuating places with a risk of accumulating over 20millisieverts/year, then they will announce an evacuation. If they keep to their established precedent of moving slowly (and erring on the side of radiation), the announcement will come in about 2 weeks (and allow another month to take effect).

Using the slider on the school map also reveals wider investigations done on previous days. I guess they are not cumulatively added to the map because yesterday's measurements may have changed by today. There are 2 measurements: at 1cm (above the soil, I assume), and 1 meter.

Measurements of the known VERY radioactive areas were done mostly on the first day.

NYT Interactive Budget Puzzle

It really isn't so hard to balance the US budget and eliminate the deficit. That was my go at it. You don't need to go back to the policies of the Eisenhower administration or even the Clinton administration. I think the hard part comes in when you have to convince 100 Senators and 438 Congresspeople to vote for your plan. Perhaps it's also a problem that there is no single person to come up with a budget and push it through (as far as I know, it's a committee thing).

Give it a try, if you haven't done so already.

New Standard Chronomenclature (2009†02•12º)

Various ways of writing and numerically abbreviating dates exist in different countries. This can be confusing when you find a document dated 02-03-04 and have no way of knowing if the creator of the document was thinking in American, Australian, British, German, French, Swedish, or another way. February 3, 2004, March 2, '04, and March 4, 2002 are among the possible interpretations. 

The most logical way is to follow the system which is implicit within numerals themselves, that of placing larger units to the left and smaller units to the right. This has the added advantage of placing your files or photographs in order when used in alphanumeric file systems. 2009-02-12 will come after 2007-02-12, 2009-01-12, and 2009-02-11, for example. 

However, aside from placing numerals in the correct or at least logical order, I have often toyed with alternative date representation systems which would reduce the ambiguity of the unadorned number by linking it with a convenient abbreviation not unlike the m, k, cm, and other units. This is needed because people will not adopt the international system overnight, or even within their own lifetimes. 

For a time, I found that writing the year as four numerals makes that clear enough, and writing the month in Roman numerals was attractive, but that completely negates the advantages discussed with data in computers. 

Something similar to the Japanese 年 月 日system (e.g. 2009年2月12日) would be ideal. These characters represent year, month (or moon) and day (or sun). Looking at the (Roman) keyboard viewer, I think the best available characters are †(option+t), •(option+8), and º(option+0) or alternatively ˚(option plus k). Since we have a Christian calendar, plop a cross thingy right down there after the year (†). The four quadrants represent the four seasons and the Earth's travel through these quadrants in its orbit. The moon is often associated with a crescent but a parenthesis is the only thing close to that, and is reserved for other uses, so consider instead the moon as a reflective, mostly dark body (90% black, albedo 0.1). Represent it with the •(option and 8 on a US keyboard). That "bullet" also reminds us that the moon was created when a large body tore through the early Earth like a bullet. Last but not least, there is the day. The day is best represented by the sun, or in this case, the degree sign º(option+0(that's a zero)) or ˚ (option+k). The really nice thing about that is that a degree is considered 1/360th of a whole (circle), and a day is 1/365.25 of a year.Close enough!  Actually, using 0 may be a superscript (?) while k is a degree sign. Depending on whether you think you will confuse today's temperature with today's date, one or the other may be preferred.  

I'd like the world to adopt this by next Tuesday, 2009†02•17º. (Everybody needs a few days to adjust.) Please make a note of it. (Persons over 65 have until 9†3•1˚.) Just remember Option/alt and t8k. (Your mnemonic is "ALTer Tate, Kay" or "Alt/t80"). 

[alt/t/8/k] OR [alt/t/8/0]
