<br />Pretty graphic but what is an "arbitrary unit"? <img src='http://208.71.34.143/public/style_emoticons/default/rolleyes.gif' class='bbc_emoticon' alt=':rolleyes:' /><br />
<br /><br /><br />

This plume info came from the United Nations - go ask them. They probably didn't want to be the lightning rod for "data" since no one else is providing the specifics! Interesting that only National News is covering that news, not local news. I should go check out Sacramento as they've reported a slight bump in radiation levels. Measurements should be in milisieverts.<br /><br />

The sievert (symbol: Sv) is the SI derived unit of dose equivalent radiation. It attempts to quantitatively evaluate the biological effects of ionizing radiation as opposed to the physical aspects, which are characterised by the absorbed dose, measured in gray. It is named after Rolf Sievert, a Swedish medical physicist renowned for work on radiation dosage measurement and research into the biological effects of radiation.<br /><br />

I'm asking you since you posted it here as proof of something I guess. The graphic is worthless. It shows nothing.

Radiation From Japan Has Now Reached Northern California

http://www.krcrtv.com/news/27244244/detail.html

REDDING, Calif. -- Small levels of radiation from Japan were detected by a federal radiation monitor in Sacramento Friday morning - the first sign that radiation from the country's unstable Fukushima plant has reached the U.S.

The U.S. Government has an extensive network of radiation monitors around the county, including systems operated by the Environmental Protection Agency (EPA) and the Department of Energy.

One of these monitoring stations in Sacramento detected miniscule quantities of the radioactive isotope xenon-133. The origin was determined to be consistent with a release from the Fukushima reactors. The levels detected were approximately 0.1 disintegrations per second per cubic meter of air (0.1 Bq/m3), which is roughly about one-millionth the dose rate a person normally receives from rocks, bricks, sun and other natural background resources.

Xenon-133 is a radioactive noble gas produced during nuclear fission that poses no concern at the detected level.

Yes, we have known for quite some time that there would be a measurable increase in radiation levels here in the US.

As Nick (OSU) said earlier, the increase is of academic interest, but has no further implications.

Agencies: No harmful radiation has hit Arizona

Agencies: No harmful radiation has hit Arizona Tribune East Valley Tribune | 1 comment

Three state agencies are watching air currents coming toward the southwestern U.S. coast from Japan and have concluded that the amount of radiation in the plume is not much different than people experience on a cross-country flight.

The March 11 earthquake and tsunami set off the nuclear problems by knocking out power to cooling systems at the Fukushima Dai Ichi nuclear plant on the northeast coast of Japan. Since then, four of its six reactor units have seen fires, explosions or partial meltdowns.

The Arizona Radiation Regulatory Agency (ARRA), the Division of Emergency Management (ADEM) and the Department of Health Services (ADHS) say people in Arizona are safe from dangerous radiation and need to be aware of potential dangers of taking potassium iodide when there is no danger.

Potassium iodide can be dangerous to people with allergies to iodine, shellfish or who have thyroid problems. It can have major side effects, including abnormal heart rhythms, nausea, vomiting, electrolyte abnormalities and bleeding.

Federal officials say there is no risk expected to Arizona or its residents as a result of the situation in Japan.

"No harmful radiation has hit Arizona". Thats a play on words. That means that radiation has hit us in AZ.

Let's assume we have measured an increase of about 1 microsievert in California.

That's about 10 BED. In other words, that's the equivalent of 10 bananas raining down from the sky!

EDIT: That's also the equivalent of smoking about 1.4% of a cigarette!

I agree there is no need to worry if you are in the states. With that said, not all radiation is the same at the same dosage.

True, but if what I'm being told is correct, my compeletely-out-of-my-a** 1 microsievert was actually way too high... and it was closer to 1 nanosievert.

So, the equivalent of about 0.1% of a banana falling from the sky.

The USA stuff is just so inane and ignorant right now. Radiation detected in California at one millionth etc, just a silly press release. The press feeds the paranoia and dilutes stuff so much that when real disaster strikes it is almost like we do not believe it is as bad as it seems. It is about time for Litchfield Joe to post but the real disaster on the nuclear side is in Japan only right now. It is a regional disaster for now. Things could get worse or better but silly press reporting about the US today just dilutes the real story and gives fodder to guys like Litchfield. Right now the hope is this remains regional only and the prayer is it is isolated to one area. This is nowhere near solved, completely understood or any less of a real crisis than yesterday.

I realize this is slightly OT, but I'm slightly agitated by the coverage of the radiation hitting the US...in that in a lot of these stories...the fact that it's NOT going to be harmful is getting buried in stories. And some are being very vague about things (leaving the door open that it could have some health impacts), and I think that's very irresponsible. I was annoyed enough, so I blogged it: http://adiabat.wordpress.com/2011/03/18/following-up-on-japan-and-media-mismanagement/

Non-stories don't get ratings.

<br />Better than weenies which are thought to be highly radioactive to some.<br />
<br /><br /><br />

See how radiation causes mutations.....from particles, to bananas, to hot dogs falling from the sky. Geez, hope there isn't more on the way - can you imagine what will fall if higher amounts are detected...

<br />I've got radiation in my basement in the form of radon.<br /><br />It puts California to shame.  No doubt, the infinitesimal radiation in my basement <br /><br />is far greater that the stuff that just crossed the Pacific Ocean.<br />
<br /><br />

WINTERYMIX: You are comparing apples to oranges. They are entirely different products. Radon originates from decaying natural uranium in the ground, and the only reason it's toxic to humans and animals is that it's concentrated in basements, attics and buildings which are not well ventilated. Radon causes 10,000 cases of cancer each year, but that's because most people haven't tested their basements/attics - or have fixed the main causes: basement floor & wall cracks, open areas around pipes into the house, etc. So it's YOUR FAULT (or the homeowner/building owner). You/they have the ability to fix the problem.<br /><br />

With radionuclides, it's not a matter of choice - humans/animals/plant life are exposed from reactor releases, nuke disasters or weapons testing. You and your fellow brethren or pets don't have a say in the matter unless you flee. Most times you're at the mercy of the weather; which way the wind blows. Nasty substances which will effect you are Cesium - which can travel thousands of miles. Strontium - you MUST remember this one from the 1950s duck & cover/cold war stuff. Then radioactive Iodine, and the rest. This is the collection of elements that is of concern from Japan's early days of the disaster, in addition to noble gasses, which are now over the United States. As days progress and the danger increases..so too the radioactive emissions increase...with the potential of endangering populations. We don't know how much or when, we only know that as the radioactivity and danger increases, so does the effects elsewhere. <br /><br />
