Ionizing radiation like that from nucler materials is not produced by a cell phone. Cell phones produce RF (radio frequency) emissions. Totally different beast.

And yes...... Uji area is too far from Fukushima to have been impacted at all.

Is tea from the Shizuoka prefecture of Japan safe?

Also, the biggest radiation exposure you get from travelling (now that they've dumped the nudie scan x-ray) is simply from being at 40,000 feet, and all those juicy cosmic rays.

This was on a while ago on tv but thought I'd post it up here

Not really tea related but this was a good episode of infinite monkey cage taking about Risk. And there's a small bit about nuclear power (fukushima) that I found interesting. Don't know how the humour will go down outside of the UK but I enjoy it :lol:

Nuclear stuff about 8m30s

Great program, thanks for the link! I actually saw Brian Cox on an episode of QI someone posted on youtube and he did a great job there as well. :)

What about the radioactive ocean water that gets into the rain or snow?

Its relevance to tea in Japan (which is the topic) is zero.

BTW, today marks the 3 year anniversary of the quake and tsunami of March 11, 2011.

... reflecting over a cup of sencha.

The primary radioactive contaminant of concern is Cesium-137. Once it gets into the ocean water, it will form an ion, as part of a salt just like Sodium or Potassium (Cesium is the next heaviest alkali metal on the periodic table). When water evaporates from the ocean, to form clouds, then rain and snow, the dissolved metals do not evaporate with it (when you evaporate salt water, the salt stays behind). Therefore the radioactive contamination will stay in the ocean water (where it is very, very, very diluted). Multiple nuclear reactors have been dumped into the ocean, and you get only nanoscopic levels of trace contamination from them in ocean food.

I am about to set this topic afloat in the sea of TeaChat ... where it may now sink or swim based upon posting.

In other words, I am unstickying the topic.

Hey long time no 'tea.'

Sorry I dont have time to read all 18 previous pages, I read a bunch but there is no summary page, so...

Am I correct to conclude that any Japanese tea sold by reputable vendors (Ippodo, Ocha, Ito En, etc) will be be safe?

I've been drinking my usual Kago Chiran for Sencha the past few years but want to get some others again.

Thanks!

"Happy Fukushima" to you ... :mrgreen:

From such a distance, we often view places such a Fukushima is simply a "land" affected by tragedy ... while it is really a people moving on and being happy (while never forgetting its history). This video makes me want to jump right in and celebrate life despite past hardships.

Very nice video. Thanks for sharing. My hip can't stop moving with the rhythm. :lol:

Great to see such positive video on Fukushima. Really alter my perception now. Since the incident, I was a bit apprehensive but I re-started drinking Japanese tea more and more and this video really give me more assurance to do it.

Cheers! :D
