Radioactive beef over cesium limit from cow raised far outside Fukushima… As Fukushima beef shipments to US resume this week

ENENews

Radioactive cesium levels above the government’s new limit have been found in beef from Miyagi Prefecture, the prefectural government said.

Meat from a cow shipped by a farmer in Tome was found to contain more than 150 becquerels of radioactive cesium per kilogram, the Miyagi Prefectural Government said Wednesday.

The stricter limit of 150 becquerels for beef and rice took effect Oct. 1. The previous limit was 500 becquerels per kilogram.


Miyagi Prefecture told the farmer not to ship any more cows until the investigation is completed, and asked nearby ranchers to suspend shipments voluntarily.

N. America’s West Coast to be most contaminated by Fukushima cesium of all regions in Pacific in 10 years — “An order-of-magnitude higher” than waters off Japan

ENE News

In the following years, the tracer cloud continuously expands laterally, with maximum concentrations in its central part heading east. While the northern portion is gradually invading the Bering Sea, the main tracer patch reaches the coastal waters of North America after 5–6 years, with maximum relative concentrations ( > 1 × 10−4) covering a broad swath of the eastern North Pacific between Vancouver Island and Baja California. Simultaneously some fraction of the southern rim of the tracer cloud becomes entrained in the North Equatorial Current (NEC), resulting in a westward extending wedge around 20°N that skirts the northern shores of the Hawaiian Archipelago. After 10 years the concentrations become nearly homogeneous over the whole Pacific, with higher values in the east, extending along the North American coast with a maximum (~1 × 10−4) off Baja California. The southern portion of the tracer cloud is carried westward by the NEC across the subtropical Pacific, leading to increasing concentrations in the Kuroshio regime again…

Financial Incentives: Radiation Exposure ‘Soaring’ As Medical Imaging Tests Overused

Natural Society

Just after it was released that CT scan radiation actually triples the risk of brain tumor development in children, new research is now ousting the fact that average radiation exposure from such medical imaging tests has skyrocketed over the past decade. And the result of this admittedly ‘excessive radiation’ is an increased risk of not only cancer, but other significant health conditions.

The University of California, San Francisco (UCSF) published the findings of the study in the Journal of the American Medical Association (JAMA), which reveals just how serious the issue of radiation exposure is. Researchers write not only how the rates in which patients are scanned by the radiation-emitting machines are much higher, but there is also some concern over how many patients receive repeat scanning — ultimately leading to higher and higher doses of radiation. For those suffering from chronic issues that need consistent ‘monitoring’ from such devices, this could mean heavy radiation levels on a highly routine basis.

High radiation that is undoubtedly spiking cancer rates, as doctors are openly admitting – the same radiation that has been coming from Fukushima in amounts far exceeding original estimations and causing an ‘unknown’ number of cancer deaths. Dr. Rebecca Smith-Bindman, a professor of radiology and biomedical imaging at UCSF, explains just how dangerous radiation exposure is when it comes to the development of cancer:

“The studies are pretty clear – high exposure to radiation causes cancer.”

Such is the case even for the common dental x-ray – the seemingly harmless imaging technique that is actually associated with a two-fold or higher increased risk of developing brain cancer. This particular research was very effective in measuring the true severity of repeat scans. While patients who received the bitewing x-rays (showing upper and lower back teeth) less than once per year were only 1.1 to 1.6 times more likely to develop brain cancer, more frequent runs proved to come with a hefty price. Those receiving frequent panorex dental x-rays (an x-ray showing all of the teeth) upped their risk by 2.7 or 3.0 times — much greater than those receiving bitewing tests less frequently. What’s more, the risk increased to 4.9 times if the patient was below the age of 10.

So why the increase in medical imaging tests? The study boldly set out to examine the incentives for the spike, even examining financial factors that could play a role. Even more boldly, they reached the conclusion that financial interests were indeed one main driving factor. A sad truth considering the fact that these financial incentives are contributing to the epidemic of cancer — particularly among young children. Smith-Bindman reports:

“One of the thoughts for the change in the rise of imaging is a change in the incentives… It suggests that financial factors may play a role, but there are other factors as well.”

Report Shows How Radiation Can Destroy DNA

Natural Society

The threat of radiation is constant and growing; too much radiation from medical testing and other sources is increasingly becoming a concern for many individuals around the world. The average child will receive more than seven radiation emitting scans for medical procedure by age 18, not to mention all of the background radiation emitted from cell phones, as well as other various electronic devices.

With the advent of the TSA body scanners, using deadly terahertz radiation only adds to the controversy. An array of DNA destroying and cancer causing devices pervade our natural lives.

A recent study conducted using THz radiation found that the radiation’s effects on genetic material are so devastating that they can actually destroy it. THz radiation effectively unzips the double helix strands, creating anomalies that would be detrimental to gene expression and replication. The report concludes by saying that TSA scanners are not only a gross invasion of privacy, but are also producing long term effects on human health that ultimately shorten the lifespan of those who are unfortunate enough to be affected by them.

Add this to the constant exposure from cell phones, cell phone towers, and other forms of radiation including x-rays from medical procedures, and you have a mega-radiation dose over time. Radiation is indeed harmful; there’s a reason why doctors leave the room after giving patients undergoing radiation a heavy lead coat.

The pervasive nature of this threat has even prompted the FDA to issue guidelines concerning radiation exposure and safety. This report notes of a proposal to create less dangerous scanners and technology in an attempt to mitigate the damage done, espically to younger individuals.

The fact that they would propose taking action shows that they know the effect of radiation is a real threat and causing damage daily. Taking this into account, you should also be aware of the dangers and necessity to protect yourself and others.

Photographer: X-ray-like image shows how radioactivity has spread throughout bodies of Fukushima wildlife

 This image was published on the photo blog of Takashi Morizumi. It appears Dr. Satoshi Mori was responsible for the x-ray-like view showing black dots spread throughout the body of a small bird from Iitate Village. The dots are said to be radioactive particles of Cs-137 internalized by eating contaminated insects.

“Takashi Morizumi is a photojournalist who covers topics in Japan and overseas such as the effects of US military bases and environmental problems. In particular, since the later half of the 90s, he has covered the damages caused by nuclear mining, testing, power plants, and the use of depleteted uranium and other nuclear weapons.” -Source

Radiation risks from Fukushima ‘no longer negligible’

Euractiv

The risks associated with iodine-131 contamination in Europe are no longer “negligible,” according to CRIIRAD, a French research body on radioactivity. The NGO is advising pregnant women and infants against “risky behaviour,” such as consuming fresh milk or vegetables with large leaves.

In response to thousands of inquiries from citizens concerned about fallout from the Fukushima nuclear disaster in Europe, CRIIRAD has compiled an information package on the risks of radioactive iodine-131 contamination in Europe.

The document, published on 7 April, advises against consuming rainwater and says vulnerable groups such as children and pregnant or breastfeeding women should avoid consuming vegetables with large leaves, fresh milk and creamy cheese.

The risks related to prolonged contamination among vulnerable groups of the population can no longer be considered “negligible” and it is now necessary to avoid “risky behaviour,” CRIIRAD claimed.

However, the institute underlines that there is absolutely no need to lock oneself indoors or take iodine tablets.

CRIIRAD says its information note is not limited to the situation in France and is applicable to other European countries, as the level of air contamination is currently the same in Belgium, Germany, Italy and Switzerland, for instance.

Data for the west coast of the United States, which received the Fukushima radioactive fallout 6-10 days before France, reveals that levels of radioactive iodine-131 concentration are 8-10 times higher there, the institute says.

Rain water and tap water

According to CRIIRAD, a huge proportion of the inquiries it has received concern the risks associated with rainwater and drinking tap water.

The institute stresses that there is no risk whatsoever, even for children, of standing in the rain without protection. But consumption of rainwater as a primary source of drinking water should be avoided, particularly among children, it said.

As for tap water, underground catchments or large rivers should not present any problem. But the institute suggests that the situation of water from reservoirs that collect rainwater from one or more watersheds, such as hillside lakes, should be examined more closely.

As for watering one’s garden with collected rainwater, CRIIRAD advises watering only the earth and not the leaves of vegetables, as absorption is faster and more significant on leaf surfaces than through roots.

Food chain

Spinach, salads, cabbage and other vegetables with large surface areas are among those food products that are particularly sensitive to iodine-131 contamination, if they are cultivated outside and exposed to rainwater. Washing vegetables does not help, as iodine-131 is quickly metabolised by the plants, CRIIRAD notes.

Fresh milk and creamy cheeses, as well as meat from cattle that have been outside eating grass, are categorised as foods that may have been indirectly contaminated and must also be monitored. Contamination of milk and cheese from goats and sheep may be of a greater magnitude than that of produce from cows.

Level of a risky dose

The Euratom Directive of 13 May 1996 establishes general principles and safety standards on radiation protection in Europe.

According to the directive, the impact of nuclear activity can be considered negligible if doses of radiation do not exceed ten micro sieverts (mSv) per year. Beyond this value, possible measures should be considered to reduce exposure, it says.

While radioactive iodine-131 is mostly present in the air in the form of gas, CRIIRAD notes that in the case of the Fukushima fallout, the main issue is to limit ingestion of iodine-131.

CRIIRAD notes that the amount of iodine-131 capable of delivering a dose of 10 mSv varies greatly depending on the age of consumers. Children up to two years old are the most vulnerable and ingestion of 50 becquerel (Bq) is enough to deliver to the body a dose of 10 mSv, according to the institute.

If the foods (leafy vegetables, milk etc.) contain between one and 10 Bq per kg or more, it is possible that the reference level of 10 mSv may be exceeded within two to three weeks, the institute added.

Radioactive iodine-131 values measured by the French Institute for Radiological Protection and Nuclear Safety (IRSN) in recent days show the following, varying levels of contamination: 0,08 Bq/kg in salad, spinach and leeks in Aix-en-Provence, 0,17 Bq per litre in milk in Lourdes and 2,1 Bq per litre in goats milk in Clansayes.

Contamination to continue over coming weeks

CRIIRAD notes that “huge amounts of radioactive material have been released by the Fukushima Daiichi plant since Saturday 12 March 2011. On Tuesday 5 April, 24 days after the accident, the releases continue. This means that the contaminated airborne masses in Europe will last just as long, with a delay linked to the movement of radioactive aerosol gases over some 15,000 km.”

It also cited a technical report from the operating company (TEPCO) and the Japanese nuclear safety authorities (NISA) which “fear releases over several more days, even weeks”.

If more fires are reported or if the operators are forced to release more steam in order to prevent hydrogen explosions, new massive waste releases will occur, the institute warned.
