Google Translation of Inspection of school children who have small amounts of cesium Minamisoma 274 (private news friend, Fukushima)
Minamisoma City の — [...] Inspection was conducted from October 11 until August 1. In this examination, the majority of school children living in the city that ended the inspection. 8 years was highest in the 45-50 girls becquerels per kilogram, 1192 becquerels of cesium-134, -137 at 1,723 as Becquerel. That translates to 0.41 mSv radiation dose in sievert is expected to be exposed before age 70.

This will break your heart too OD
Annya’s parents lived in a town so contaminated by the Chernobyl nuclear disaster that it was destroyed and buried. When she was four, Annya was diagnosed with a brain tumor. Photographer Robert Knoth visited Annya in Belarus in 2005 and returned in 2011.

is it BQ per Kilogram or for the total body (“8 years was highest in the 45-50 girls becquerels per kilogram,”) –
because as human we have around 4000-8000 Bq in total in our body due to the K40 isotope (natural Potassium component) – but the difference is that K40 is a beta radiator and C137 has gamma radiation in addition which has a longer range.

1 disintegration per second = 1 Bq (just in case…)

Tepco uses the ICRP method of determining internal radiation. The ECRR method increases this 500 times or more. That would mean the highest radiation in a human here is equivalent to the topsoil amounts which caused mandatory Chernobyl evacuation.

how do you convert becquerels to millisieverts??
ive looked everywhere and havent found a thing
Report Comment
Yes thats possible, fisrt you need to search for BQ to Gray / h (Gy/h), it depends on distance, kind of source (energy) and media which its travels through. The quivalent dose is more complicated for beta and gamme, and CS137 roughly 1Sv = 1 Gy.

The thing is if they are just testing for Cesium, what do you think this represents out of total radionuclide load. This would be a marker for a much greater load of a variety of radiological contaminants would it not?
Report Comment
It would go like this !
Exposure to 1 sievert (the unit used to measure radiation absorbed by human tissue) automatically results in radiation sickness: 1 sievert contains 1,000 millisieverts and you need 1,000 microsieverts to get one millisievert.
Generally, human beings are exposed to between 1 and 5 millisieverts per year.

Look at my 10 Sv/h video, there you can see the radiation on the video. The camera is a GoPro Hero HD. Starting with 1 Sv/h you will see the dots. This radiation will also be visible to the human eye (I dont test this .–) as reported by Curie/Becquerell making their radium tests.

I made the video, but I didnt hold the camera – made at the Helmholtz research center munich.

probably they looked for gamma rays and tested the spectrum, CS137 typically has 661,66 keV gamma with 84% intensity (others are beta: 513,97 keV and 1175,63 keV) – source minitables de radionucléides

@ westcoastguy
my reply just got down links for converting BQ to Dose rates.
Report Comment
@rdklein – thank you for those links
I know the maths is beyond me but I might pick up some basic knowledge from them. Besides it’s good to have some recommended addresses to pass on.
Recently I came across this online converter that might be worth bookmarking:

Yes this is a nice calculator but it cannot convert between the different units, as more parameters are required then.
But from old to new SI units an back and with different scales its just great.
Difficult stuff.

Thanks ~ I hoped for this kind of reply

Why is Radiogardase not being given to these children? The German company Heyltex has ramped up production of it in anticipation of issues from Japan even! (www.heyltex.com) It is only Prussian Blue, purified to medical grade, and it flushes Cesium from the body in 1/3 of the natural time. I can understand costs, or patent issues, but children and adults who are showing these levels of Cesium should be treated as soon as possible!

minisieverts, becquerels, rads and all that other stuff makes my brain hurt. I’m a lot more hard wired for creative shit and not mass destruction.
I know one thing……this just SUCKS really hard!
Love to all you enenewsers.

Does anybody know, is there any way that they can test/measure whether and how much plutonium and strontium are inside of a human body?
Report Comment
Yes,..as I understand it. They put you through like a C/T tube, and they can see your ‘internal emitters’.
Am I correct friends?
