Is Los Angeles At Risk For Radiation Exposure Following Japanese Nuclear Power Plant Explosion ?

UPDATED : Breaking news :


UPDATED AND CORRECTED ! Concern for the safety for U.S. cities like Los Angeles following Japan's nuclear plant explosion.

In the latest news report, The Daily Mail reports that the "Nuclear Regulatory Commission admits it is 'quite possible' radiation could reach the U.S." Plus, given that Pacific Ocean jet stream moves wind currents from Japan to the West Coast of the United States, should there be any U.S. public health advisories issued for at-risk cities, like Los Angeles ?

Even as David McIntyre, a spokesman for the Nuclear Regulatory Commission, said, "Right now it's quite possible that there could be some radiation floating over the United States," the NRC "downplayed the threat to Americans," however. Mr McIntyre told the AFP: "We don't think that it would be particularly harmful... even in a worst case scenario," according to The Daily Mail.

Japanese government authorities are issuing emergency orders, advising residents to follow safety procedures and take other precautions following the nuclear power plant explosion in Fukushima. Residents within the immediate Fukushima radius are being told to stay indoors, turn off air conditioners, and avoid drinking tap water.

In The Los Angeles Times, news so far has centered around any lessons to be learned from the Japan earthquake itself, not from the damage to energy infrastructure, like to nuclear power plants, for example.

Thus far, the Japanese government has not issued radiation risk warnings to other countries. As of Saturday evening Japanese local time, an evacuation perimeter of 20 kilometers around the Fukushima nuclear power plant. On the RT news channel, a correspondent has reminded viewers that the Soviet government suppressed for several days the truth about the dangerous radiation levels following the Chernobyl nuclear power plant meltdown.

No announcement have yet to be made about any emergency preparedness plans for residents in Los Angeles, or other major U.S. West Coast cities.

Risk of exposure to the U.S. West Coast by radiation from Japan nuclear power plant explosion

UPDATED : Breaking news :


CORRECTED ! Could a risk exist of nuclear radiation danger to the U.S. West Coast following the Japanese nuclear power plant explosion ?

In the latest news report, The Daily Mail reports that the "Nuclear Regulatory Commission admits it is 'quite possible' radiation could reach the U.S."

If the nuclear power plant explosion in Fukushima, Japan, generates large amounts of nuclear fallout, then people living in the West Coast of the United States could be exposed to nuclear radiation, if radiation enters the Pacific Ocean jet stream.

Indeed, "The wind direction for the time being seems to point the (nuclear) pollution towards the Pacific," Andre-Claude Lacoste, of the French Nuclear Safety Authority, told AFP, according to The Daily Mail.

Conceivably, some amount of radiation would reach islands in the Pacific Ocean, such as Hawaii, followed by the West Coasts of Canada and the United States. Large U.S. West Coast cities, such as Los Angeles, San Francisco, and Seattle, would be at risk.

It is not yet known if scientists with the Environmental Protection Agency and the Department of Homeland Security have issued any emergency advisories in the United States. Even as David McIntyre, a spokesman for the Nuclear Regulatory Commission, said, "Right now it's quite possible that there could be some radiation floating over the United States," the NRC "downplayed the threat to Americans," however. Mr McIntyre told the AFP: "We don't think that it would be particularly harmful... even in a worst case scenario," according to The Daily Mail.

People living along the West Coast of the United States seemed to have largely escaped mass damage from the tsunami following the 9.0 magnitude earthquake in Japan. Now, the dangerous new threat facing the U.S. West Coast is radiation exposure.

Japan nuclear fallout map -- it started out as a hoax, but could it turn out to be true ? At least, as it concerns the direction of any fallout ?

UPDATED : Breaking news :


UPDATED ! No official link-back can be found to the Japan fallout forecast map. (The graphic has been removed, but it can be seen by clicking on the preceding link.) Further research indicates that the graphic was a hoax. Nevertheless, the direction indicated on the map is consistent with the Pacific Ocean jet stream and with a forecast by an Austrian meteorological model. There is no way to confirm the rad level predictions. (A ''rad'' is a measured unit of absorbed radiation dose.) Furthermore, comments to this blog post suggest that the trade or prevailing winds, such as the westerlies, would carry any nuclear radiation particles, not the jet stream. No contradiction, though, suggests that the direction of the map was incorrect. In fact, nuclear radiation is already being detected by the U.S. Navy down wind from the site of the nuclear power plant explosions. In the latest news report, The Daily Mail reports that the "Nuclear Regulatory Commission admits it is 'quite possible' radiation could reach the U.S."

Early on Saturday morning (New York Time), a suspicious map circulated on the Internet. The map was exposed to be a hoax, because the rad levels were unrealistic, and there was no official link-back to the map. But with several explosions at the Fukushima nuclear power plant, could nuclear meltdown occur ? And could wind currents carry dangerous levels of radioactivity ?

The suspicious map, bearing the logo of Australian Radiation Services, indicated that exposure to radiation following a likely nuclear fallout from the nuclear power plant explosion in Fukushima, Japan, could reach the West Coast of the United States within 6 to 10 days time. While the map may appear suspicious, the direction of the spread is consistent with the Pacific Ocean jet stream and/or trade or prevailing winds. And if the rad levels were wrong, has a scientist issued any realistic levels of radiation that would be spread by wind currents in the event of a nuclear meltdown at Fukushima ? Confirmation that nuclear radioactivity is now in the wind currents comes from The New York Daily News : "The U.S. 7th Fleet, positioned about 100 miles northeast of the Fukushima Daiichi nuclear power plant to deliver aid to Japan's coastal region, moved its ships further away due to 'airborne radioactivity' and contamination found on its planes." Making the worst case scenario -- a nuclear meltdown -- all the more likely is the fact that employees at the Fukushima nuclear power plant have abandoned their posts and fled their responsibilities -- this comes after a third explosion at the doomed power plant.

Even as David McIntyre, a spokesman for the Nuclear Regulatory Commission, said, "Right now it's quite possible that there could be some radiation floating over the United States," the NRC "downplayed the threat to Americans," however. Mr McIntyre told the AFP: "We don't think that it would be particularly harmful... even in a worst case scenario," according to The Daily Mail.

Meanwhile, here is a YouTube video of the first nuclear power plant explosion at Fukushima from a Japanese news program. It shows what could be white smoke and/or steam rising from the building as a result of the nuclear power plant explosion. Video Credit : ProducerMatthew.


Separately, supplemental reports have come in that the Japanese government has imposed an evacuation area spreading 20 kilometers around the nuclear power plant in Fukushima. Prior to the explosion, energy scientists had been managing the nuclear emergency at the power plant by releasing steam, to relieve pressure in the cooling system. One risk from releasing steam is that critical water in the cooling system is lost ; if too much water is lost, there is a depletion in the cooling system, thereby leading to a risk of exposing the core, leading, in turn, to a nuclear meltdown.

Apparently, radiation would be carried across the Pacific Ocean by the wind currents, such as the jet stream. Scientists have not yet determined the amount of radiation that has been released by the nuclear power plant explosion. So far, the only information available is coming from nations nearer to Japan. United States government officials have yet to make any risk assessments in connection with radiation exposure.

Fukushima is approximately 150 miles north from Tokyo. Residents within the immediate Fukushima radius are being told to stay indoors, turn off air conditioners, and avoid drinking tap water. It is not yet known what nuclear emergency advisories are being made, or preparations being taken, at other large large cities in Japan. Later on Saturday, however, there was news that the company that operates the power plant planned to use sea water to cool down the reactor's core, and it was also reported that authorities were planning for the distribution of Iodine to residents. (Iodine can be taken to prevent the absorption of radiation by the thyroid, reported MSNBC.)

[Updated Monday, 14 March 2011 9:20 am EDT] : Whereas the original photograph that circulated last weekend was not an official map, the forecast direction where wind currents would carry airborne radioactivity is generally consistent with the jet stream and the westerly wind currents over the Pacific Ocean. Tom Costello, an NBC News correspondent for The Today Show, predicted that nuclear radiation would be carried by wind currents over the Pacific Ocean, but would ''dissipate'' over the ocean, presumably before any radioactivity would reach the U.S. West Coast. No scientific evidence was given to support that radioactivity would completely dissipate, however.
