Any health effects from the more abundant and diverse background radiation would completely swamp anything from reactors.
Feynman could have been as great as Einstein, Carver believes, but he operated in the background radiation of Bohr, the great intimidator.
The emergencies ministry urged calm, saying background radiation levels were normal after what it described as a "meteorite shower in the form of fireballs".
New figures on background radiation levels recorded 60km northwest of the Daiichi power plant have also been released this week by Japanese physicist Tsuneo Konayashi from Fukushima Medical University.
One of the main challenges for anyone attempting to ascertain the health effects of Chernobyl radiation is that there is so much background radiation in the atmosphere to begin with.
Dr. GERBER: It's approximately four times the natural radiation dose that we all receive annually in the Unites States, as a result from background radiation due to radon and other materials.
That low-flying helicopter crisscrossing the skies over the San Francisco Bay Area for the next three days is gathering data on background radiation levels, according to the National Nuclear Security Administration.
This new photogenic moment, released Thursday, comes courtesy of the European Space Agency's Planck space telescope, which detects cosmic microwave background radiation -- the light left over from the Big Bang.
One, called XENON100, which is also in Gran Sasso, ran for the course of a year, but only saw two "events" - not enough to rule out that this might have been some stray background radiation.

But notice, that extra tail of a line crosses the entire range of background radiation on Earth, what is considered normal, what humans and every other life form has lived with long before we split the atom.
But Dr Mousseau suggests a more likely explanation is that evolution has already been at work near Chernobyl, killing off individual birds that cannot cope with the background radiation and allowing the genes of those that have some tolerance to be passed on.
In specific reply to your assertion the author of this piece did not offer any evidence refuting the LNT hypothesis, I disagree, he specifically cited factual, observed experience of no increased cancer risk in areas where normal and persistent background radiation levels are well above levels the LNT hypothesis would assert must have statistically significant higher cancer risk.
In 1966 Kenneth Greisen, Vadim Kuzmin and Georgiy Zatsepin showed that high-energy charged particles (cosmic rays are mostly atomic nuclei, and thus positively charged) should be slowed by collisions with the photons of the cosmic microwave background (radiation left over from the Big Bang that permeates all space).
They have produced highly accurate maps of the Cosmic Microwave Background (CMB) radiation, which has its origins in the very early stages of the Universe.
According to LNT, any and all radiation doses, even background and below, are harmful and linear with dose.
The background is that chips that go into space need to be radiation hardened.

The new map is a smart byproduct of the European Space Agency (Esa) telescope's main mission which is to survey the Cosmic Microwave Background, or CMB - a pervasive but faint glow of long-wavelength radiation that comes to us from the very edge of the observable Universe.

As background you need to understand that Busby is insistent that even very low levels of radiation lead to high and extreme health effects.

The radiation doseage to biological organisms can be as much as several thousand times the background dosage.
