“The God Particle”
CERN may have found exotic Higgs ‘impostor’ particle

CERN announced the discovery of a new particle last week, it was very, very careful to not explicitly call that particle the Higgs boson, instead citing “strong evidence”.

The God Particle is only a marketing term may have contributed to increased media interest, many scientists dislike it, since it overstates the particle’s importance, not least since its discovery would still leave unanswered questions about the unification of Quantum chromodynamics, the electroweak interaction and gravity, as well as the ultimate origin of the universe.

The HIGGS BOSON is a massive scalar elementary particle predicted to exist by the Standard Model in particle physics. At present there are no other known fundamental scalar particles in nature.

The Higgs boson is the only Standard Model particle that has not been observed. Experimental detection of the Higgs boson would help explain the origin of mass in the universe.

The Higgs boson would explain the difference between the massless photon, which mediates electromagnetism, and the massive W and Z bosons, which mediate the weak force. If the Higgs boson exists, it is an integral and pervasive component of the material world.

STANDARD MODEL OF PARTICLE PHYSICS:

http://www.youtube.com/user/Best0fScience#g/c/4A8C50311C9F7369

The Standard Model of particle physics is a theory of three of the four known fundamental interactions and the elementary particles that take part in these interactions. These particles make up all visible matter in the universe.

Every high energy physics experiment carried out since the mid-20th century has eventually yielded findings consistent with the Standard Model.

Still, the Standard Model falls short of being a complete theory of fundamental interactions because it does not include gravitation, dark matter, or dark energy. It is not quite a complete description of leptons either, because it does not describe nonzero neutrino masses, although simple natural extensions do.

Tokyo Electric Power (TEPCO), operator of the Fukushima Daiichi nuclear plant, said it would release more than 10,000 tons of contaminated water that was about 100 times more radioactive than legal limits.

The tiny creatures, eaten in shrimp rolls and shrimp salad, occupy a pivotal role in the oceanic food chain and may serve as early indicators.

IS IT 10 MILLION OR 100,000 TIMES NORMAL???


“TEPCO officials said Sunday that radiation in leaking water in Unit 2 was 10 million times above normal – a report that sent employees fleeing. But the day ended with officials saying that figure had been miscalculated and the level was actually 100,000 times above normal, still very high but far better than the earlier results.” Source: Read More>>>>

TEPCO retracts radioactivity test result
Tokyo Electric Power Company has retracted its announcement that 10 million times the normal density of radioactive materials had been detected in water at the Number 2 reactor of the Fukushima Daiichi nuclear plant.

The utility says it will conduct another test of the leaked water at the reactor’s turbine building.

The company said on Sunday evening that the data for iodine-134 announced earlier in the day was actually for another substance that has a longer half-life.

The plant operator said earlier on Sunday that 2.9 billion becquerels per cubic centimeter had been detected in the leaked water.

It said although the initial figure was wrong, the water still has a high level of radioactivity of 1,000 millisieverts per hour.

Workers were withdrawn from a reactor building, a major setback for the effort to avert a catastrophic meltdown, and radiation spreads to Boston, California, Washington, Pennsylvania and Las Vegas all reporting positive readings


“Radiation hits have been found in California, Washington and Pennsylvania, according to the DPH. All those positive readings are part of the nation’s RadNet radioactive monitoring system. The Las Vegas’ Atomic Testing Museum this week also reported detecting low levels of radiation, the Associated Press is reporting this afternoon. Positive readings have also been made in Colorado and Hawaii.” Source: Boston Herald News Paper Reports

The levels detected are far below levels of concern.

Daily Data Summary

Last updated on Sunday, March 27, 2011 at 17:41:02.

As the Nuclear Regulatory Commission has said, we do not expect to see radiation at harmful levels reaching the U.S. from damaged Japanese nuclear power plants. As part of the federal government’s continuing effort to make our activities and science transparent and available to the public, the Environmental Protection Agency (EPA) will continue to keep all RadNet data available in the current online database. EPA is working with its federal partners and has deployed additional monitors to Hawaii, Alaska, Guam and the Northern Mariana Islands.

EPA is utilizing this existing nationwide radiation monitoring system, RadNet, which continuously monitors the nation’s air and regularly monitors drinking water, milk and precipitation for environmental radiation. The RadNet online searchable database contains historical data of environmental radiation monitoring data from all fifty states and U.S. territories.

EPA will provide daily data summaries of our radiation air monitoring efforts. We will continue to keep all RadNet data available in the current online database.

March 27, 2011

As of 8:30am (EDT) EPA’s RadNet radiation air monitors across the U.S. show typical fluctuations in background radiation levels. The levels detected are far below levels of concern.

FAMILIES RUSH FOR WATER!

Tokyo’s tap water contains twice as much radioactive iodine than deemed safe for infants, officials said Wednesday, sparking food safety fears as plumes of smoke forced employees to evacuate the country’s damaged Fukushima nuclear plant yet again. Source of information provided by france24.com

“Engineers are trying to stabilise a six-reactor nuclear plant in Fukushima, 250 km (150 miles) north of the capital, nearly two weeks after an earthquake and tsunami battered the plant and devastated northeast Japan, leaving nearly 26,000 people dead or missing.

Tokyo’s 13 million residents were told not to give tap water to babies under 1 year old after contamination hit twice the safety level this week. But it dropped back to allowable amounts on Thursday.”

“The purpose of robots is to do those dull, dirty and dangerous missions — so dangerous is certainly what we’re talking about here,” says Tim Trainer, a vice president at iRobot, an American firm that has sent four of its robots to the company that owns the Fukushima Dai-ichi nuclear power plant.
