Fukushima DRY WELL Dose measurements: Unit 1: Instrument Failure. /// Unit 2: 25 minutes and you’re dead.

First, this is “kinda cool”, a visual time-lapse tour through DOSE measurements in Japan from March 11 through May 11, 2011 (see right below, click on image to see, or here).  On a side-note, dose measurements can be useful to gauge radiation dangers, but it’s more often used to make light of fallout (as most dose measuring stations are well above the surface, and as such don’t reflect fallout levels very well…).  Anyhow, it’s the date-adjustable feature that’s cool, I think:

The much less cool is this graph (bottom of blogpost) of the radiation dose outside the containment vessel, but still in the reactor building (a.k.a. the Dry Well) for the different units at Fukushima Daiichi.  I don’t quite understand why Jeff of Rense.com announces stuff so sensationalistically* and deceptively, but oh well…

Yet then when you click on it, the website it links to: http://atmc.jp/plant/rad/? , showing the now-public radiation dose measurements (in Sievert per hour – see my Radiation units page for more on that) for the seveal reactor buildings (vessel and dry well) at Fukushima Daiichi, and, for Unit 1 it states clearly that the measuring device is broken… (instrument failure).

I don’t mind that for his listed often-bs UFO links, I find those often entertaining nonetheless, but for this topic… LAME.  And since I list him as a source, I’ll point out the lameness sometimes too (not always though, that could be a blog in itself…).  Here are the stats.  Given 7 Sv/hr is deadly, regardless of Unit 1’s measuring device giving out, it shows how hazardous of a mess this still is.  In Unit 2:  17 Sv/hr in the drywell…  (In there, without extremely protective gear, one would receive the maximum allowable ANNUAL dose for civilians in just over 4 seconds… (20,000 µSv).  Even with the emergency-increased legal maximum allowable level for Japanese nuclear workers, they’d reach their maximum ANNUAL maximum dose in under a minute.  And those are not ‘instrument failures’.

LEFT: INSTRUMENT FAILURE. Right: correct... Wowza. Click to see latest at SOURCE: http://atmc.jp/plant/rad/?

*not sure that’s a word…, but you get the idea…
