I AM IN JAPAN !!! :-D
I’m lagging a bit behind on my blog. It’s already been an awesome and interesting last 10 days in ‘The land of Yoko Tsuno’… More coming soon! —
The other week, Tuesday November 5, 2013, I continued my flight from Salt Lake City to Seattle, onward to Tokyo, Japan.
On board, I checked gamma radiation with my MedCom Inspector Alert Geiger Counter. It showed the to-be-expected completely natural and not particularly dangerous exposure to high altitude ‘cosmic rays’ (from outer space, mainly super novae and such).
Starting in Seattle (SEA-TAC), about to take off. For help with what “microsievert per hour” means, see my Radiation Units page.
Note: Radiation fluctuates, so pictures are often just showing an example of either a value near the average, or one of the extremes (lower or higher end), or random. More accurate measurements for an average often require more time.
Photo, below: Waiting for take-off in SEATTLE, WA (USA), as the airline talks about how awesome they are: 0.047 µSv/hr, a very normal (on the low end) of background radiation at sea level. Although Seattle continues to get whiffs of radiation from Fukushima in sporadic rain-out events (such as this one for “Seattle Summer 2013“), it is one of the few areas in the US for which fallout deposition maps were released (see my May 2012 blogpost “Fallout Maps for the United States“).
Higher up, doses can be measured that would be extremely worrisome if it was due to radioactive dust particles in the air. But here it is just from distant sources, mainly cosmic rays from super-novae:
Flying over the North Pole, I’ve seen it as high as 6.0 µSv/hr. This is NOT to be confused with doses from fallout! !–> The whole “dose rate” concept is instrumental in the nuclear industry’s deception game. Dose rates from radioactive fallout can be extremely low, yet thousands of times more health-hazardous in the long run than the much higher doses received at higher altitude. To better understand this, please check out my newer blogpost, “The Dose Deception – Why 0.20 µSv/hr (from fallout) can be far more dangerous than 2.00 µSv/hr (from cosmic rays).The inverse square law for ionizing radiation illustrated.”
PS: Also, please read my DISCLAIMER. I am an independent explorer of realities, not a certified expert, nor aligned with any supposed nuclear or government authority. (Perhaps that’s better, since many officials have been shown to be lying, but I’m just letting you know that I do not expect you to take my word without thinking for yourself. I encourage critical open-minded self-study and I welcome corrections if you spot an error.)
For more on this difference between external and internalized sourced doses, see my attempt to put some info on this together (from 2011, needs updating and more): Radiation Exposure Effects page. More about this coming soon!
Welcomed warmly to Japan. Signage is usually in Japanese, with the basics also in English. Piece of cake to find your way.
- Time zone difference:
- Off to Shinagawa in Tokyo, to catch a train heading south in the morning:
On the subway train:
Shinagawa! Train station to transfer to the train south in the morning!…
More coming soon!
