unless we have the limits in those units... I wonder it must be MBq/km2
by dean 8/8/2011 3:10:27 AM

That was everyone's learning curve. The numbers were in an odd expression.
Edano calculated the converstion to this:
MBq = 1,000,000 Bq, km² = 1,000,000 m²
so 1 MBq/km² is the same as 1 Bq/m²

I guesstimated about 91 bq to a square inch of soil.

Thats good that it isn't really high. There was an online post someone claiming it was sky high. Still not sure why it took METI until july to release march data...

The spinach contained 54,100 Bq/kg of I-131 and 1,931 Bq/kg of cesium. That means consuming 1 kilogram (2.2 pounds) of fresh spinach would yield a radiation exposure of 1.2 millisieverts, or half the average annual natural exposure from soil and cosmic rays, based on Bloomberg calculations using a formula posted on the website of Japan’s

Elaine was asking earlier and Will wanted to make sure he had the numbers correct for something he is working on.

thats important to correlate what they report to some limits and get the units right ... most plant numbers have Bq's/kg..etc...
by dean 8/8/2011 3:29:27 AM

so Bq/m2 would convert over to some limit for ground contamination

Radioactive strontium-89 and strontium-90 were discovered in soil at the plant on 18 April, amounts detected in soil one-half kilometer from the facility ranged from 3.4 to 4400 Bq/kg of dry soil THAT'S an example

All soil samples taken 60 km from Fukushima plant survey exceed legal limit — Minimum of 326,000 Becquerels per sq. meter

I thought we had the limits on the web site somewhere.. they are so hard to remember
by dean 8/8/2011 3:39:26 AM

Yes I put all the limits on the FAQ page. I should grab those and put them into the resources on the group web. I added a weather links page but need to link it into the navigation to find it easier. Thunder had a big write up of resources plus what you and some others posted.

good info, thanks Dean. I'm off to bed before the storm hits.

www.tepco.co.jp and just look at this for /leakage/pump failure/blockage/rupture/etc potential ! Flippin eck, it looks to be designed with failure built in, Tepco will be so happy

sewage in Tokyo is becoming a problem eco.nikkeibp.co.jp
by elainekirk 8/8/2011 8:46:00 AM

Tepco have a unique leak here more to follow
by elainekirk 8/8/2011 9:06:19 AM

And here we have it the leak is in the electrical system www.tepco.co.jp

Study says nuclear fuel at Fukushima reactor possibly melted twice

@Edano does that mean cooling started then it flared up again ?

---------- Study says nuclear fuel at Fukushima reactor possibly melted twice TOKYO - Fuel inside one of the reactors at the crippled nuclear complex in Fukushima Prefecture, which was believed to have been kept cool at the bottom of the pressure vessel after its core suffered a meltdown, has possibly breached the vessel after melting again at the bottom of the vessel, an expert's study showed Monday.

The study by Fumiya Tanabe, an expert in nuclear safety, said most of the fuel at the No. 3 reactor may have fallen into the containment vessel underneath, and if so, the current method used to cool the reactor would need reviewing, which could force the plant operator to revise its schedule to contain the five-month-old disaster.
