up 1.60

The amount of radiation rose to 1.318 microsievert per hour -- a figure 33 times bigger than usual -- in Tochigi Prefecture's capital of Utsunomiya, the Tochigi prefectural government said.

Meanwhile, Chief Cabinet Secretary Yukio Edano said the radiation level reached 400 millisievert per hour near the No. 3 reactor at the Fukushima No. 1 plant Tuesday morning. The amount is 400 times higher than the allowable limit for citizens in a year.

On Monday, the radiation level near the No. 3 reactor peaked at 3,130 microsievert or about 3 millisievert per hour.

This above numbers are something to measure by.

I just wonder if that cloud for some strange reason was to blow west...how much of the food and crap we buy from China if would it become contaminated and if so would they tell us?

Chiba counter- Instantaneous spike from 1.49 to 1.70. Then about a minute later, sudden drop back down to 1.47

now reading at 1.67

A bit of comparison might help -

Bananas are radioactive - 365 bananas, which would mean 1 per day, has about 36 microsieverts.

If the readings are currently at 1.6 microsieverts it's basically the equivalent of eating just over 20 bananas.

If you were in a banana plantation, you would be exposed to more radiation.

A flight from Frankfurt and Bangkok would result in 30 microsieverts of radiation.

A CTscan has 2200-3300 microsieverts and an x-ray delivers 20-100 microsieverts.

1 rad = 0.01 gray (Gy); 1 Gy = 100 rad;
1 rem = 0.01 Sievert (Sv); 1Sv = 100 rem
1 rad= 1 rem; 1 Gv = 1 Sv

Here are the levels for Radiation poisoning: chart

Second ETA:
I went back to look at the picture and noticed the M... i think it's a M before the SV. Hard to tell.

1 mSv = 100 mrem = 0.1 rem so this would be normal radiation levels.

In this thread here: US Air Force WC-135 Detects Deadly Radiation Over Pacific (US in 24hrs)

I noted that a Live Stream of a Geiger Counter in Tokyo, Japan was working 1-2 hours ago... has since gone "offline"


Ok this seems very strange and worth noting.

This website... usstream.tv: Live Feed - Tokyo, Japan Geiger Counter has been showing the radiation levels in Tokyo on a live feed.

It was working a few hours ago. I just checked on it and guess what?

Now it is "OFF AIR".


Weird because the website loads, so its not "over-loaded" by web traffic. Just "offline"
Is it part of a Conspiracy? Anyone can translate the Japanese on that webpage for us?

So they are being exposed to ~ 150 rem/hr. Currently which is about the radiation 5 hours after a nuclear blast.

1-2Sv is NOT good.



No because the geiger counter shows mSv
Hence 0.0015 Rem i think.

Thanks for the examples. I believe the geiger counter online in Chiba is reading microsieverts per hour. So for a person currently in Chiba to get the same dose as one x-ray, it might take about 10-50 hours at current average rates. We are not talking about deadly levels here, at least not yet. I started this thread more as a reason to monitor rising levels of radiation. Not how deadly it currently is.

it is.

1.2Sieverts is 1.2000*106 microsieverts - no where near the levels detected.

No, good thread S&F from me!

I only posted examples because people were confused as to what it really means.

And it's hell confusing to try and decipher from the net, so many terms, levels, etc it can be alarming.

Not micro sieverts that are in banans,thats bananas,sieverts SI multiple conversionssievert range

Decimal ranges from Sv,Micro,etc. * 1 Sv = 100 rem * Micro 1 mSv = 100 mrem = 0.1 rem * 1 μSv = 0.1 mrem * 1 rem = 0.01 Sv = 10 mSv * 1 mrem = 0.00001 Sv = 0.01 mSv = 10 μSv

Get the picture 1 sievert=100rem,1 microsievert=1msv=100mrem=0.1 rem,and lower=,and lower=

I understand. I didn't mean for my post to sound that way.Your knowledge is much appreciated in this thread.

Huh? You lost me. Banans? I said Bananas, they're not sieverts in them, they're microsieverts.

Here's a better converter for you.
Equivalent Dose

and

Banana Equivalent Dose


The equivalent dose for 365 bananas (one per day for a year) is 36 μSv (3.6 mrems)


lol no I don't get the picture....

Everyone, I found a mirror for the live Tokyo geiger counter. See link below-

Tokyo Geiger Counter (mirror)- Link


There was a massive spike about 4 hours ago. It's nice that it shows the history of the readings.

As long as the range is below 3.0 sieverts alls well,exactly not microsieverts,I am not lost but for words,good info eitherwise man
Peace

You're insane!


1,000 mSv (1 sievert) in a short term dose is about the threshold for causing immediate radiation sickness in a person of average physical attributes, but would be unlikely to cause death. Above 1000 mSv, severity of illness increases with dose.
If doses greater than 1000 mSv occur over a long period they are less likely to have early health effects but they create a definite risk that cancer will develop many years later.


3 sieverts is lethal. 1 sievert is the threshold for immediate radiation sickness..

Oo
