Message from U.S. to U.S. Citizens in Japan

Under the guidelines for public safety that would be used in the United States under similar circumstances, the NRC believes it is appropriate for U.S. residents within 50 miles of the Fukushima reactors to evacuate.

In making protective action recommendations, the NRC takes into account a variety of factors that include weather, wind direction and speed, and the status of the problem at the reactors. Here is a link to results of two sets of computer calculations used to support the NRC recommendations: http://www.nrc.gov/reading-rm/doc-collections/news/2011/11-050_Attchmt.pdf.

In other news, the U.S. Embassy continues to update American citizens as the situation develops. U.S. citizens in need of emergency assistance should send an e-mail to JapanEmergencyUSC@state.gov with detailed information about their location and contact information.

    I can understand the evacuation within the 50 mile radius,but for people on the west coast of the U.S. to get excited seems a bit of an overreaction.

    PLEASE DON’T HIDE OR MINIMIZE EXPOSURE LEVEL ESTIMATES FOR WEST COAST!! I have 3 children under 6 years old and I can send them to live with family in Minnesota if you give our family notice and don’t hide information.
    Given the documented leaks and the current risk of full meltdown in at least one reactor, as well as the scientifically known 7 day direct wind patterns from Japan to Northern California, can a NRC scientist please post the official Plume computer data models showing wind patterns and calculated atmospheric dispersion with full radation exposure calculations?
    Please do this using the same, clear language and data as the NRC Advisory to US Citizens living in Japan, WITH SPECIFIC EXPOSURE ESTIMATES. Even if these are low, it would be useful to have transparency on this issue.
    Also, could the NRC please create a credible peer reviewed site with Plume models and exposure estimates so that other credable scientists from major government agencies and universities can comment with full public transparency?

    With respect to the calculations, what exactly is meant by maximum dose? Are doses for locations in the ocean excluded? I am trying to make sense why many of the dose values seem to drop off by a factor of about 2 for every ten miles for one set of calculations and seem to level off after about 10 miles for the other. My guess it has something to do with differences in the forecast meteorological conditions. Is it possible to provide any more insight as to what was assumed for these two hypothetical release scenarios? For example, what would be the duration for these release scenarios?

    What about air travel between Asia and US? On my Seattle to Taiwan flight, we seemed to travel down the spine of Japan, but I did not look at the map that carefully. If significant radiation is release, will air travel be impacted? Should I leave for home ASAP? Could you please provide altitude info in your plume modeling?

    I agree with the above comment. I saw the link to the NRC from the CDC WEB page and am disappointed there isn’t more here. I am in Vietnam on work travel and have been seeking reliable info. The NRC should step up as the authority! I have found the information you have provided as VERY helpful. Now is your hour to shine! Thank you

    I am sitting at my house in the U.S.A. looking at the issues you are facing with your powerplants. I see that you are using the helicopters to try and cool down the spent rods. My question or comment is this: You have pumpers on site to use the water cannons. Why dont you use the Helicopters to place a rigid temporary pipe much like a candy cane into the affected area. I am sure your fire pumpers could pump water up to a certain head. Once you have a constant supply of cooling water, you can refocus your efforts to containing the other issues. I know nothing about nuclear powerplants but I do understand the fundimentals of plumbing. Pull from the ocean with a suction line. supply to the candycane side of pipe via supply side of fire pumper. All you will need to do is make sure you don´t run out of fuel for the pumper. I know this is a simple thought from a simple person but sometimes people can over engineer something without seeking the obvious.
