Kelp along the California coast was found to be contaminated with radioactive material from a nuclear plant damaged in the March 201 earthquake and tsunami that struck Japan, according to a recent study.
The levels were also about the same as those measured in British Columbia and Washington state after the 1986 Chernobyl nuclear power plant explosion.
Oh well. I'm sure they will tell us it's below the harmful levels, the seals were just dying of old age, blah, blah.
Researchers at California State University, Long Beach found that the kelp contained radioactive iodine, cesium, xenon and other particles at levels unlikely to be detrimental to human health but much higher than the amounts measured before the disaster.
Medical experts, however, said the disaster's impact on U.S. public health was likely insignificant. Exposures of large numbers of people in past nuclear accidents, such as Chernobyl, have indicated that any radiation that reached the West Coast wouldn't have much of an effect.
Abstract
The Fukushima Daiichi Nuclear Plant, damaged by an earthquake and tsunami on March 11, 2011 released large amounts of 131I into the atmosphere, which was assimilated into canopy blades of Macrocystis pyrifera sampled from coastal California. The specific activity calculated to the estimated date of deposition/assimilation ranged from 0.6 to 2.5 Bq gdwt–1, levels greater than those measured from kelps from Japan and Canada prior to the release. These 131I levels represent a significant input into the kelp forest ecosystem. Canopy-forming kelps are a natural coastal dosimeter that can measure the exposure of the coastal environment to 131I and perhaps other radioisotopes released from nuclear accidents. An organizational mechanism should be in place to ensure that they are sampled immediately and continuously after such releases.

The claim that there are "safe levels" of radiation is bull#. Radiation is unsafe at any level. Any exposure to radiation increases your risk of some kind of medical consequences. Namely, cancer. There is no so-called safe level of radiation.edit on 12-4-2012 by Atzil321 because: (no reason given)
There is no so-called safe level of radiation.
I just happen to be one of the people that thinks ANY amount of man-made radiation is too high. (Had to add man-made because I can already see the people pointing out solar radiation )

Also the people on ATS tend to fearmonger a lot when they are not told the full story, and what they say in the article about the readings and the exposure to human health could be true(I don't know about the numbers of the readings at this moment), but people with no knowledge of radiation danger will allways think otherwise.

I supposed everyone just dies when they go out in sunlight then do they?
Don't be a smart-ass and that wouldn't happen.
During mining and milling of zircon, care must be taken to keep dust levels down. Then when zircon is fused in refractories or ceramics manufacture, silica dust and fumes must be collected. This may contain the more volatile radionuclides, Pb-210 and Po-210, and the collection of these gases means that pipeworks and filters become contaminated.
The main radiological issue is occupational exposure to these radionuclides in airborne dusts in the processing plant. Waste produced during zirconia/zirconium production can be high in Ra-226, which presents a gamma hazard, and waste must be stored in metal containers in special repositories. Powders from filters used during zirconia manufacture have been assayed as high as 200,000Bq/kg of Pb-210 and 600,000 Bq/kg Po-210.

It's kind of funny you mention that, because everytime i have been xrayed being tooth or bones, i have asked them what the risk is, they allways said "there is no risk", and i NEVER believed them.
So no i don't believe anything i am told, far from actually, but i do no my facts and judge from there.
My mom died from cancer, my father is dying from cancer, my sister have cancer, and i propably will die from cancer to, not to mention my freinds and cancer.
It's every freaking where, and is propably caused by pollution of air, water or food, what is causing al this cancer, nobody really know, but there is no need to fearmonger about it, because it's no secret that anything manmade could be the cause, including radioactivity of different kinds and amounts.
Don't take me for an idiot just because i trust some people and there mention, i'm just not paranoid like most people are today because they don't know who to believe, and i allways try to understand what i am told, and read up about it, untill my inteligens barrier is kicking in, and it's pretty high i can say without bragging.

And now you are inferring that I said all natural radiations were safe, which I most certainly did not.
We can play this game all morning, but being on a phone I don't feel like feeding your diatribe.

Naturally occurring radionuclides fall into three categories: primordial radionuclides, secondary radionuclides, and cosmogenic radionuclides. Primordial radionuclides, such as uranium and thorium, originate mainly from the interiors of stars and are still present as their half-lives are so long they have not yet completely decayed. Secondary radionuclides are radiogenic isotopes derived from the decay of primordial radionuclides. They have shorter half-lives than primordial radionuclides. Cosmogenic isotopes, such as carbon-14, are present because they are continually being formed in the atmosphere due to cosmic rays.[1]
Now Fukushima is not only manmade radiation, but it was done deliberately, as all the 9/11 earthquakes and diasters are, including yesterdays.

Sorry, some pages don't fully load on my phone.
That has been their generic response to radiation levels for the past year. No surprise that they are sticking with it... people seem to believe it anyways.

Damn, I was in the mood for some shrimp tonight too...
