Update, links, a couple of pictures

Things are quiet in Tokyo this week.  My family left on Saturday, and this Monday I started my regular commute to work (I was staying at their apartment while they were here, which was only a 10-15 minute walk away from the office).  The Tokyo Metro seems to be running almost normally for the most part.  However, the darkened areas (due to efforts to minimize electricity usage) of the underground are a reminder that things are not back to normal – and are not likely to be for a while yet.

Efforts to contain the damaged nuclear plants in Fukushima continue, though right now it seems to be progressing at a rate of 2 steps forward, one step back as the radiation dangers around the immediate area force workers to proceed with extreme caution.  There’s a sense of helplessness (at least from my part) since there is really nothing the average person can do expect hope and pray that things will come under control soon.  We in Tokyo are safe, but not far away are people putting their lives on the line.

This is probably old news for all Japanese readers, but still thought I’d post the English information pages on the possible power blackouts.  Energy usage now is fairly stable and the power blackouts are minimal, but as the humid summer months come, people are expecting that electricity outages will resume again in the near future.

Spring is definitely on its way, and the weather is getting nicer every day.  However, just about 250km away, people are struggling to contain a crisis that has the potential to impact not just Japan but the rest of the world.  It’s rather surreal.

I’ve uploaded a couple of pictures I took of early spring buds while my family was here.  It is odd to realize how much more I appreciate their beauty in times like these.

Humor News

Careful of those bananas!

In its usual humorously informative way, XKCD created the following chart which provides another measure of understanding radiation exposure.

Exposure to 1 Sv all at once (as opposed to spread out over time) is dangerous, and qualifies as minor radiation sickness.
1 Sv =  1,000 mSv (millisievert) / 1 mSv = 0.001 Sv
1 Sv = 1,000,000 ?Sv (microsievert) / 1 ?Sv = 0.000001 Sv

Link from Metropolis (daily radiation levels)

I don’t know if there are any sites in Japanese that also show this information, but just came across a page on the Metropolis site that offers measurements of daily radiation levels.  It’s not official by any means, but for English readers, another source of information…
