Will you temporarily stop purchasing Japanese Greens?

6,46mSv in the soil of a park near Tokyo is nonsense?
http://enenews.com/6-46-microsieverts-p ... playground

It's not mSv, it's uSv. But still quite high, i remember something like ~10uSv is average dose per day that people receive in normal conditions. For an adult this means nothing, but for growing kids radiation is more dangerous. I would not want to experiment on my kids to see will it actually affect them or not... But also i know that there are plenty of places in big cities that have even higher background radiation. That is one of many other reasons i prefer living in a small city.

What's the threshold for evacuating people?

What's the threshold for evacuating people?

I doubt it's enough for evacuation, but certainly they should forbid from entering such places before they could deactivate territory, it's above legal limit set by Japanese government, it was 20mSv per year? If i understand right, level of radiation in that park is close to safe limit for rad workers in US, i.e. ~50mSv per year. But for this you would have to spend whole year lying on the ground.

Most scary part about this, that it was discovered by someone not related to government and after quite long time starting from accident.

Seems it was right to avoid products from prefectures near Fukushima, no one can guarantee that's it's safe, they are so damn slow

Why would one stop buying tea from Japan? The affected areas comprise less than 2% of the tea production of the country and only produce very low-grade filler tea. The slightly irradiated tea from Shizuoka that doesn't get sold this year will just be blended into the tea produced next year for low-grade blends. All of the decent readily available leaf tea comes from Aichi on west, anyhow. I only buy the good stuff, so I am not affected, except by price fluctuations based on demand for better teas

The usual standard for contamination is Decays/(UnitofTime * Unit of Area), I.E. Bq/M^2. Contamination limits are set around this standard, not a standard of Dose/time, so this measurement is meaningless (it could be a. Radiation also falls off with the square of distance from a point source, where the kids were playing it probably wasn't even measurable (if it were, the scare story guy would be measuring it there). There is also no telling where it came from, or what it is, maybe it's some particle from another source. If it's really tiny, even eating the contaminated-whatever-it-is wouldn't get you to the measured dose rate, as you have to average the exposure across the whole body. He was really close to the ground, it's likely not that high above ground.

Dose rates (sieverts/hour) are only used for radiation worker protection, and a rate of 50uSv/hr is the lower limit for posting an area as a radiation area.

No telling what the real story is here.

Yes, because it's notorious that radioactivity lasts for only 1 year...

Tea from Kanagawa: 1330bq/kg.

Way too much for me.
I don't care what Shizuoka's governor says. I car about MY health. And my health is saying me to not buy japanese green tea anymore, as long as there's only a minute amount of radiation.

There are many other tea growing regions, everything starting from Uji didn't get any change in radioactive elements.

I wish people would be careful like that with everything, there are so damn many other things that are totally ignored

Tea gets blended. Who guarantees me that Shizuoka tea doesn't get in any other blends from Uji for example?

[Kevangogh]

Do you think Uji tea companies want to blend Shizuoka tea in with their tea? I don't think so.

If you apply this logic not only to Japanese teas, all foods and things will become dangerous. For example, who will guarantee no dangerous amounts of pesticides were used in tea you will buy from China? People trust vendors and rely on common sense. Or do you wear gas mask when you use car, go out from home etc? Sine there are quite a lot of airborne harmful particles, especially in big cities, which are harming health quite a lot.

You can always get information if tea was blended or not.

Just opened 2010 organic Warashina Supreme from the O-C. Warashina teas from Shizuoka for 2011 are showing up "hot" and will likely not be seen for at least a year, at least not what we are used to seeing.

Too bad, as Warashina is also an excellent source for organic asamushi.

I am anxious to see how this has held up.

Among recent purchases is an organic asamushi from Kagoshima (also O-Cha), seems to be a rarity for an asa from Kago ... that one is in Cold Storage until I emty at least one other Japanese green.
