Description: On 29 Oct 2011, I measured radiation in front of a gate of an elementaly [sic] school in Kiwa city, Chiba pref. Japan The monitorinig place is 200 km from Fukushima Nuclear power plant, and 35 or 40 km to Tokyo, called “Tokyo Hot Spot”.
The monitor indicates 0.28 micro Sievert per hour in air at chest hight [sic], 3.52 on roadside sand at ground level.
Kashiwa = Red dot NE of Tokyo
I am afraid that schildren’s lung may chatch the dust from this sand in dry and windy days.
100m from this school, There is a Garbage Ash Landfill facilities of Kashiwa city.
It is told that radioactive materials are con densed in garbage ash. Kasiwa city laid such high polluted ash in the landfill place near this elememtary school till June 2011.
Measuring instrument is made of Ukraine. ECOTEST MKS-05.

Description (Google Translation): 3.68 micro sievert per hour on a sand road in front of the school gate school. Before measuring the radiation dose in Kashiwa, Chiba Nishi Elementary School urges rich October 29, 2011. Space (chest level) value of 0.19 micro sievert per hour.
Is concerned that children are taken to soar as the lungs of dust in the wind.
Just 100m from the site location in elementary school, there is a landfill in Kashiwa.
Kashiwa until June, had been disposed of in landfill final disposal of general waste to 25 tons of ash out of the home.
And is reported to be greater than the reference dose ash from it in October, dig the ashes, packed in drums have been stored.
The distance is about 200km from the Fukushima Daiichi nuclear power plant. Of about 35 ~ 40km in Tokyo. The instrument, made by Ukraine. ECOTEST MKS-05. Only gamma rays were measured.

Thanks for the laugh! I would be such a drop-out there!

The long life expectancy in Japan is headed for African and Belarus standards. The denial by the Japanese government to mandate many more dead zones or evacuation zones is a genocide decision. The people must make their own decisions to move away or stay and suffer great personal losses. It is so hard when the genocide killing agent is virtually invisible and the government denies any health risks.

(3.68 x 24 x 365)/1000 = 32.2 milli sieverts a year = 61.9% above mandatory evacuation level

Indeed that is the calc that brings it home.
A simpler calc for immediate consumption is to multiply the Micro per hour by 8, and that is a pretty good estimate of Milli-Sievert.
2 milli-sievert per year is damaging, why do 50% of us get cancer? But anything over 20 is serious stuff. And once it become internal emitters, you are pretty much screwed.

Like the way he provided a map to his shocking findings. All those brilliant civilians put their government to shame.

All ionizing radiation causes similar damage at a cellular level, but because rays of alpha particles and beta particles are relatively non-penetrating, external exposure to them causes only localized damage, e.g. radiation burns to the skin. Gamma rays and neutrons are more penetrating, causing diffuse damage throughout the body (e.g. radiation sickness), increasing incidence of cancer rather than burns.

“ECOTEST MKS-05. Only gamma rays were measured.” Did they only measure for gamma rays, or was it not measurable? For CS 137 there should be also beta rays (though they might be blocked more easy) – The MKS-05 has a beta mode also. I suppose its form CS137 or what is the most spreaded nuklide in this area ?

“The next mode is called the “Gamma Dose” mode. Think of it as accumulated dose mode. It is displayed in mSv (millisieverts) to 3 decimal places. Note that this measurement has no unit of time. It is total accumulated dose. By doing some simple math, we can see that if we are in an environment of 0.10 µSv/h, we will get our first count on this display in 10 hours (0.001 mSv = 1.0 µSv). This indication is reset if the unit is turned off. It continues to count when the unit is asleep. More on sleep mode later. The speaker does not click in this mode.”
I don’t understand it. I’m wondering if measuring Gamma only value is a component of total value measured by any standard GM tube?

A GM tube usually (the classic ones ) cannot distinguish between the different radiation, one ray leads to a hit (if its reacting with the matter/gas inside and ionizing it). So something to block the beta rays is needed (usually a metal cover). The GM tube counters are calibraed using a CS137 source (also shielded to only produce gamma rays) and these results are used for the DIsplay in either Gy/h or SV/h (also estimated Sievert is a difficult to measure unit).
The GM tube also gets into saturation if the dead time is reached (two rays hit in an interval smaller than the dead time , the time for the tube to recover). With a higher dose the GM counter usually show error or ZERO (we did some measurements on Geigercounter with tubes in the Buchler Device – some get into saturation after some MiliSV/h).
Thats also the reason the BFS uses two GM tubes with different ranges so higher rates can also be covered.
Report Comment
A GM tube also cannot distinguish between the different energy types so a CO60 sources gives a different result (the usual GM tubes – there are analog tubes also but seldom in standard Geiger Counters). Neutrons usually cannot be detected (they need a converter) though the QF factor is much higher (like ALpha) ALpha can be detected when the gM tube has a thin layer of special material (Glimmer) so they pass through.
