Press Release (Mar 28,2011)
The results of nuclide analyses of radioactive materials in the air at the site of Fukushima Daiichi Nuclear Power Station (7th release)

---

On March 22nd 2011, as part of monitoring activity of the surrounding 
environment, we conducted nuclide analysis of radioactive materials 
contained in the air which were collected on March 20th and 21st 2011 
at the site of Fukushima Daiichi Nuclear Power Station, which was 
damaged by Tohoku-Chihou-Taiheiyo-Oki Earthquake. As a result, 
radioactive materials were detected as shown in the attachment. 
Therefore, we summarized the results and reported them to Nuclear and 
Industry Safety Agency as well as to the government of Fukushima 
Prefecture today. (previously announced)

On March 27th, 2011, we conducted nuclide analysis of radioactive 
materials contained in the air which were collected on the same date 
at the site of Fukushima Daiichi Nuclear Power Station. As a result, 
radioactive materials were detected as shown in the attachment. 
Therefore, we summarized the results and reported them to Nuclear and 
Industry Safety Agency as well as to the government of Fukushima 
Prefecture today.

We will continue the sampling survey the same as this one.

1. Thanks! Real data are good to see.

So far, I've looked only at the first pdf file. All the figures are below the allowed limit for workers by at least a factor of 10. That's good.

Of course, these figures only represent materials in the air, and don't include data for surfaces and the ground.

2. Yeah, real numbers certainly help

They do a decent job of keeping things in perspective. (The situation appears to be better than some say, and worse than others say.)

Mind you, the figures come from TEPCO… (caveat lector.)

[MineralMan]

3. Well, they're the only source, so...

I'm sure independent figures will be available at some point.

4. There are independent data sources (like sensors in parking lots and such)

However (to my knowledge) none from from on site.
