And then, you need to know what legal limit your talking about or what the legal limit is based on.
The level you should only be exposed to for short periods of time in an emergency where its important to get shit done and you risk a small but no zero chance of getting cancer in the future.
The level that medium term exposure is okay and you risk a smaller still but not quite zero chance of getting cancer in the future.
The level that pretty much continous level exposure to that level or less is okay and your risk of cancer is so low its vitually in the noise.
This is a photo of the Sendai ferry that I took in May last year. The photo was taken from the rooftop parking lot of a supermarket that we went into to buy snacks and drinks for the long journey back to Hokkaido on the ferry. It amused us that the ferry looked just like another apartment building, that there was no sea at all visible anywhere near it.
My husband said he is likely to be there for some months now. Right now his group are liasing with towns in the area, gathering information on what they need doing, and apportioning staff for the next few weeks and months.
In lighter news, the leader of a fire department rescue group which bravely faced danger at the plants cried in an interview, which made news. I was only sort of aware of that, so I may have the fact wrong.
It’s been found that his 18-year-old daughter stars in a barely legal DVD. http:// livedoor.2.blogimg.jp/amosaic/imgs/c/7/c723b2ca.jpg
Although not technically porn, you don’t want that link to show up at your office computer.
Thanks for all the information, Hokkaido Brit. I was just wondering about your husband this morning.
The links are really interesting. The Geiger counter map explains what the Japanese norms are for radiation exposure in a way that helped me (at least) to understand the significance current readings.
The earthquake video is impressive. It’s amazing to see how long and intense the quake was.
Not sure this has been posted yet, but I found an Australian site with some well done before and after tsunami pictures of different areas of the coast.
tunnels and trenches outside the buildings are full of radioactive water.
hundreds of tons of radioactive water inside several buildings must be removed and stored before work can continue to power up the plant’s regular cooling system.
Contaminated water inside Unit 2 has tested at radiation levels some 100,000 times normal amounts, plant operator Tokyo Electric Power Co. said.
airborne radiation levels outside Unit 2 exceeding 1,000 millisieverts per hour — more than four times the amount that the government considers safe for workers.
Contaminated water inside Unit 2 has tested at radiation levels some 100,000 times normal amounts.
The 3 workers were released from hospital today. They have no visible lesions, and doctors expect no future health problems due to this accident, but will continue to have follow-up visits. The men’s exposure level is now said to have been 1 to 2 sieverts.
Power company officials say plutonium has been detected in the soil outside of the stricken Japanese nuclear complex.
Tokyo Electric Power Co. says in a statement that the plutonium was discovered Monday in five locations around the plant, which has been leaking radiation for nearly two weeks.
The only part of that chart that I’m not understanding is what the exposure relationship is between the red section and the gold Chernobyl section. Do all the doses in red section equal the gold section? I’m just curious, because this chart is the first sense that I’ve been able to make of the whole exposure thing, except for the red/gold part. Great chart.
The little inset of the red chart on the gold chart shows what fraction of the gold chart all the red doses combined make up. The doses in the red chart add up to about 15 Sieverts, which is a little less than 1/3 the dose represented by the gold chart (50 Sieverts, which in turn is over 6 times the “you’re totally boned” dose).
Short interviews with some of the Fukushima Fifty. It was interesting reading about their perspective on developments. There are also a couple facts mentioned I hadn’t heard elsewhere, such as
