Radiation Check in Japan- Extreme radiation difference in the same area, PART 1

After seeing the radiation check videos from our city, i decided to double check. I am measuring for two months, but never got too high levels. This first video is from the area around our house - where the numbers are very normal. But today, i was taken by asuperdry (youtube user living in the same city, who took the mentioned videos) and had chance to see the extremely big radiation hot spots. The problem is, my checks around the place, I am leaving in, or in the central city are always normal probably because the altitude is higher here, but if the altitude changes and you go to lower ground spots, you can experience really high radiation. Off course the air is OK everywhere, independent form the altitude. Problem is the soil and ground. Competent offices should act immediately and clean the dirty zones asap, as they did in the kindergarten by the Kashiwa station, where they changed the sand in the playground - btw, thank`s to asuperdry-san wife activities. The kids are playing now in playground with radiation 0.08microsieverts. I know, that this Fukushima radiation level is peace of cake comparing to radiation levels, when the French government (among others) tested their nuclear bomb in the pacific. Bombs create and disperse more critical radionuclide (i.e. uranium, plutonium, strontium, etal) in the air and sea than the nuclear power plant. But event that, we should not ignore any of this problems and do as much as we can, to avoid the worst scenario.

So you met Asuperdry. Thank you for this. Say hello to him. So who was wrong now you or me or Asuperdry? Where is your truth now. You saw it on your own eyes.

@aristoman007 watch the other videos, if you have time. anyway, none of us have professional geiger. university of tokyo is doing everyday measurements with professional equipments here, in their kashiwa campus - daily average is around 0.25. you can check it at their site"東京大学環境放射線情報". they are independent from tepco, or government, trying to urge them with open letters etc. they are quite active and adequate.

To summarize: The increased level of radiation you measure in the air is due to the decay of airborne Cs (and it is increasing when you move closer to the ground where a lot of Cs is deposited), whereas the normal, pre-Fukushima, level was mostly due to the cosmic radiation and radioactive gas Radon which is constantly escaping from the ground and buildings.

@p1hysiognomist thanks!!!

Well be careful...

The plastic is blocking the alpha particles...

[p1hysiognomist]

Beta has very little penetration power so as it stays outside you can be protected with your regular clothes but if it is inhaled of digested your cells which are in contact with hot particle will be heavily damaged. Some of these damages may lead to a cancer but most will have no consequences. What proven is that than more hot particles make their way into your body than higher chances you have to develop cancer.

[p1hysiognomist]

You should be aware that the main danger is currently not the gamma radiation you mostly measure with your device rather than hot particles like microscopic dust which contaminated with radioactive Cs. When you inhale or digest radioactive Cs it will decay emitting gamma radiation (electromagnetic waves) and beta radiation (electrons).

@MsB0RG can you explain it a little bit more?
