I really do not understand why there are attempts to minimize this drama. Even 1.000 mSv/year is not really something healthy....or am I mistaken???

I am interested in ACCURACY not Drama.
The news media is interested in DRAMA because it sells.
They could give a rat's behind about accuracy. The ONLY time they are accurate is when it is a Sports Score - That is from my Newspaper owning Father-in-law. He could not even get his Son's science fair project right when he reported that his son won top honors and his son was sitting at the table with him as he wrote the article!
Well then Fukushima nuclear accident is a drama that must be reported with accuracy, that's why it's important to specify if it is mSv/year or mSv/hour, something that makes a HUGE difference
2. Radiation Monitoring
Dose rates at the Fukushima site continue to trend downwards.
In 28 of the 45 prefectures for which data are available, no deposition of radionuclides was detected in the period 18 to 25 March. In seven of the other 17 prefectures, the estimated daily deposition was less than 500 becquerel per square metre for iodine-131 and less that 100 becquerel per square metre for caesium-137.
On 26 March, the highest values were observed in the prefecture of Yamagata: 7500 becquerel per square metre for iodine-131 and 1200 becquerel per square metre for caesium-137. In the other prefectures where deposition of iodine-131 was reported, the daily range was from 28 to 860 becquerel per square metre. For caesium-137, the range was from 2.5 to 86 becquerel per square metre.
In the Shinjyuku district of Tokyo, the daily deposition of iodine-131 on 27 March was 220 becquerel per square metre, while for caesium-137 it was 12 becquerel per square metre.
No significant changes were reported in the 45 prefectures in gamma dose rates compared to yesterday. In general, gamma–dose rates tend to decrease due to the decay of short-lived radionuclides such as iodine-131.
Two IAEA teams are currently monitoring in Japan. One team made gamma dose-rate measurements in the Tokyo region at 8 locations. Gamma-dose rates measured ranged from 0.08 to 0.15 microsievert per hour, which is within or slightly above the normal background. The second team made additional measurements at distances of 30 to 41 km from the Fukushima nuclear power plant. At these locations, the dose rates ranged from 0.9 to 17 microsievert per hour. At the same locations, results of beta-gamma contamination measurements ranged from 0.03 to 3.1 Megabecquerel per square metre...

We had beautiful spring-like weather here in Tokyo today. I went jogging over by the imperial palace and it was packed with other runners. There were also tourists and retired couples out for a stroll. Then I went and bought some groceries in the busy Shinjuku district where there was plenty of food available despite the hoards of shoppers.
When I got home I turned the TV to CNN International and learned that most Tokyo streets are deserted due to the fear of radiation. I also learned that food supplies are dangerously low (as I unpacked the several bags of food that I had just bought). Then they announced that fuel supplies were also critically low and they showed a random gas station with a long line of cars waiting to get their gasoline rations. I peeked out the window at the gas station across the street and noticed that there were two cars waiting for their turn at the pump.
Does CNN International exist in a parallel universe?

To Roger Sowell
There are two things that were happening that create problems
1) The release of radioactive chemicals/particles are a PUBLIC concern. This occurs during the ventings and should there be something to cause the fuel rods to be destroyed in a fashion that causes particles of the fuel rods to be thrown into the air. I’m not seeing a lot of information that indicates the latter occurred at these plants.
2) When fuel rods that have been in use (e.g. spent fuel rods) lose their shielding there is nothing to stop the gamma emissions and this becomes a serious WORKER problem. It is not a public problem because if you are far enough away, you will get little or no dose.
Here’s an example. I helped install a 12,000,000 Curie Cs-137 irradiator in Thorton Colorada back in the ’80′s. I moved every single rod of cesium into a pool of water. I was twenty four feet away from the rods with 20 feet of water between me and them. I got no dose. None. I calculated, that without the water, at this distance I had 1.85 seconds to get a lethal dose of radiation. I also calculated that if the unshielded cesium was just sitting someplace, a person needed to be about 1/2 mile from them to be at the 2 mR/hr (.o2 Sv/hr) line which is relatively safe if you do not sit there for a year. Anyone at a mile was very safe.
I suspect at Fukishima that the water levels in the spent fuel pools kept dropping, thereby increasing the gamma radiation dose in the area. Until they could get more water shielding on the spent fuel, workers were in big danger. It sounds like this happened more than once with workers pulling back until the water levels (shielding) were restored.
I keep seeing folks try to make a big deal about the US Navy moving around. Well, DUH! Would you stand downwind of the smoke from a fire? Same basic question, would you stand downwind of a potential radioactive material release? It is one of the first basic rules of any kind of chemical (and radioactive materials are chemicals) emergency response – Get upwind from the source of the problem. The Navy is not stupid. However, those who are making this an issue have zero common sense.

I hope you all say a prayer and offer a thanks to those workers who are battling the problems at the plants. They have to work in full gear: anti-C clothing and respirators or self-contained breating apparatus. They have been working in confined spaces that are hot and without lights. You have no idea how brutal this can be. I’ve only been in a few situations where I had to dress out and do moderate work and it wasn’t dark, confined and hot (well, one time it was hot). Two hours was my limit. I have so much respect for these men who are working so hard to keep you and I safe.

Roger and others,
I also have an engineering degree (Mechanical), I also have 25+ years in nuclear operations and training. I was a licensed operator for 8 years and senior operator for another 8.
Some have downplayed the significance of this event but FAR more have overplayed the significance. Yes there are areas on the site that have lethal doses of radiation if you spend enough time standing in that location. For instance if you stood in the 40R/hr field for ten hours you would incur a dose approximately equal to the LD50 dose. There are areas of any plant that have lethal doses of radiation if you are dumb enough to stand there long enough, these areas are locked at commercial plants. Dose rates off site have NEVER been immediately dangerous to life and health.
This is a serious nuclear accident and I concur with the INES scale rating of 5 based on what we know. However, it isn’t the nuclear or public health catastrophe you , and others, are making it out to be. If, as it seems, the contamination off site is primarily I-131 then it will be gone in about 1 month because radio iodine has a half-life of 8 days. As others have pointed out, the rest of Japan’s infrastructure is responsible for far more deaths than these nuke plants during this event.

....Talked with my industry contacts this week.
Re-affirmed that all the plants in my state had additional Diesel generators put in during the ’90′s. They are in earthquake, bomb, flood, tornado, hurricane proof buildings. They are ELEVATED (about 40′ above the ground).
They contain 2 weeks worth of fuel. Part of a program known as “station black out” from the NRC.
Japan CAN be faulted for NOT having this level of defense in depth.

Either way this kind of info is disturbing.
Even if it is 1 million times, things are not good at all.
